Drone company Zipline delivers medical supplies and clinical laboratory specimens on four continents and is used in the US by several major healthcare networks and retail organizations
Unmanned aerial vehicles (UAVs), commonly referred to as drones, continue to demonstrate their value in the medical industry. In February, WellSpan Health announced it will soon begin using drones to deliver prescriptions to patients and to transport medical supplies and clinical laboratory specimens between its facilities located in Pennsylvania.
WellSpan Health, one of the leading healthcare systems in Southern Pennsylvania and Northern Maryland, is partnering with Zipline, a supplier of drone logistic services, in the endeavor.
“We’re making our [healthcare] system lower cost, faster, and more sustainable by bringing this exceptional technology to South Central Pennsylvania,” said Roxanna Gapstur, PhD, RN, President and CEO, WellSpan Health, in a news release. “We know the easier it is to access care the healthier people can be. With Zipline, we’re connecting healthcare straight to your front door.”
Zipline’s Platform 2 (P2 Zip) drone will be used for the venture. The drone is designed to fly in almost all weather conditions. If true, this would be a boon to the drone delivery service industry.
Previous attempts to implement drone delivery services have been hampered by a typical drone’s low performance in bad weather such as heavy rain and high winds. This seems to be what has held back wide adoption of drone delivery in the US.
“WellSpan continues to reimagine what healthcare can look like for our patients. With Zipline, we’re creating a future for our patients, where getting a prescription filled is as simple as pressing a button,” said Roxanna Gapstur, PhD, RN (above), President and CEO, WellSpan Health, in a news release.

Delivery of Medical Supplies Direct to Patients’ Front Door
ABC27 reported that “WellSpan will be the first health service in the state of Pennsylvania that will introduce this type of technology and delivery system.”
According to the drone company’s website, Zipline:
Serves more than 4,000 health centers worldwide and more than 45 million people.
Has completed more than one million deliveries.
Plans to operate more flights annually than almost all the major US airlines by next year.
Delivers 75% of Rwanda’s blood supply outside Kigali, the country’s capital city.
Additionally, Zipline’s all-electric, zero-emission drones reduce carbon emissions by an average of 97% when compared to gas-driven vehicles.
Each P2 Zip drone features Zipline’s autonomous airspace Detect and Avoid (DAA) deconfliction technology and contains fully redundant flight systems.
“This acoustic system is composed of a series of small, lightweight acoustic microphones and onboard processors used to navigate airspace and grant 360-degree awareness with a range of up to 2,000 meters,” DRONELIFE reported. “This innovative onboard system enables the aircraft to autonomously detect and maneuver around other aircraft and obstacles in real-time, making large scale autonomous commercial operations more feasible.”
According to a fact sheet, the P2 Zip drone can carry loads up to eight pounds and has a cruising speed of 70 miles/hour. It’s service range is either a 10-mile radius or a one-way trip of 24 miles. It only requires two feet of open space to execute a delivery and can hover at more than 300 feet above the ground while delivering a package.
“Zipline has been improving access to healthcare for eight years. Together with WellSpan Health we will bring prescriptions and medical products right to patients’ doorsteps with fast, sustainable, and convenient delivery,” stated Keller Rinaudo Cliffton, co-founder and CEO of Zipline, in the news release.
Other Healthcare Drone Delivery Services
Dark Daily has published many ebriefs about drones being used for medical supply and clinical laboratory specimen deliveries.
As drone delivery technology continues to improve, UAVs are more likely to be used in healthcare situations. If the issue of bad weather has been resolved, it’s reasonable to assume that within a short period of time clinical laboratories may begin receiving many more samples to test via drones.
Drone program will enable delivery of medical laboratory samples during the day, rather than just at night, allowing daytime sample processing that will increase efficiency and shorten time to results
Healthcare network clinical laboratories continue to explore the use of unmanned aerial vehicles (UAVs), commonly known as drones, to safely deliver medical supplies and clinical laboratory specimens between locations. Dark Daily has covered several similar pioneering drone programs taking place around the world in recent years.
The latest medical laboratory company to launch a drone delivery program is Interpath Laboratory, an independent full-service medical laboratory in the Pacific Northwest.
In partnership with Arizona-based Spright—the drone division of Air Methods, a patient transport company with 300 bases in 48 states—Interpath recently announced the launch of its drone delivery pilot program for delivering lab testing specimens from Yellowhawk Tribal Health Center to Interpath’s medical laboratory in Pendleton, Oregon.
The two organizations hope the initiative will expedite the turnaround time needed for test results, thus allowing for timelier diagnoses and improving patient care and outcomes.
“Many communities located in remote or rural areas lack timely and convenient access to essential medical supplies and service,” said Joe Resnik (above), president of Spright in a press release. “We look forward to this proof-of-concept, showcasing drone delivery’s ability to solve many of healthcare’s existing access and efficiency challenges, while also improving patient care and experience.” (Photo copyright: KVS Technologies.)
Replacing Automobile-based Medical Laboratory Specimen Delivery
“If this pilot program is successful and we are able to utilize this service, our patients have the opportunity to benefit from more rapid test results and access follow-up medical procedures and services,” stated Aaron Hines, CEO of Yellowhawk Tribal Health Center in a press release. “This project could help us further our mission of providing high-quality, primary healthcare for the Confederated Tribes of the Umatilla Indian Reservation (CTUIR).”
Currently, patient samples taken throughout the day at various Yellowhawk facilities are picked up and delivered to Interpath’s clinical laboratory in the evening via gasoline-powered vehicles. A successful drone service would allow lab test specimens to be repeatedly picked up and delivered to the lab for analysis throughout the day.
“Medical laboratory services in rural areas frequently must invest intensive time and resources into sample pick-up,” said Tom Kennedy, president of Interpath Laboratory, in the press release. “We anticipate Spright’s drone delivery service will alleviate many of the drawbacks and costs associated with automobile-based delivery. This initiative represents an example of our embrace of innovative solutions that provide more efficient and effective services to our clients.”
In February, Spright held test flights that transported clinical laboratory specimens from Yellowhawk Tribal Health Center to Interpath’s main medical laboratory in Pendleton, Ore. The 15-mile flight used a Wingcopter 198 drone (above) which employs beyond-visual-line-of-sight (BVLOS) technology. Manufactured in Germany, the Wingcopter 198 has a wingspan of five feet ten inches and can carry up to 13 pounds. It has a range of 46 to 68 miles, and a maximum speed of approximately 62 to 90 miles per hour, depending on the weight of its load. (Photo copyright: sUAS News.)
Other Clinical Laboratory Drone Deliver Programs Worldwide
Innovative approaches, such as the utilization of drones to make clinical laboratory specimen deliveries, can help circumvent many of the challenges in delivering healthcare to rural areas. But UAV delivery networks work equally well for faster specimen transferals in urban environments as well, leading to timelier diagnoses of diseases and ultimately to better patient outcomes.
Goal of university’s yearlong CHURP test was to validate the use of unmanned aircraft systems (UAS), commonly known as drones, in the delivery of medical supplies across SUNY’s campus
Just as hospital systems worldwide are exploring the feasibility of using drone technology to deliver clinical laboratory specimens and medical supplies between healthcare settings and medical laboratories, SUNY Upstate Medical University also has joined the growing list of healthcare providers that have added unmanned aerial vehicles (UAVs), or drones, to their specimen/supplies delivery services.
Traditional delivery of similar items normally takes about seven minutes. The drone delivered the same test kit in just two minutes, according to Government Technology(GT).
Then, “To prove that drone deliveries can be scaled up, the team conducted more medical deliveries in three locations throughout Syracuse two weeks ago, sending supplies from the hospital to a medical laboratory, from the hospital to a surgery center, and from a pharmacy to a second hospital,” GT reported.
Tony Basile, Chief Operations Officer at NUAIR, told GT the flight was a “proof of concept demonstration to show that medical deliveries can be made by drone when speed is essential, such as when tissue samples taken from a surgery patient must be delivered rapidly to a laboratory in a different building.”
Special FAA Waiver Allows Drone Flights Over Certain People
The FAA’s 107.39 waiver allows a drone operator to fly over people who are not participating in the operation and over those who are not covered under a structure or within a stationary vehicle. The January flight marked the first time the FAA’s 107.39 waiver was used for such a drone operation, a DroneUp press release notes.
The SUNY and the NUAIR alliance began formulating the concept of using drones to make medical deliveries more than a year and ago. At that time, there were concerns that a nearby highway project would disrupt normal clinical laboratory specimen delivery operations. The highway separates the hospital from a surgery center and finding a way to expedite deliveries despite slow traffic was essential, GT reported.
“They’re not going to want to wait 20 minutes for a tissue sample to get to the lab because the highway is coming down,” Basile told GT.
Challenges Encountered with Drone Delivery of Clinical Specimens and Supplies
In late spring, the team conducted additional deliveries to further prove the efficacy of using drones to transport medical supplies. They successfully transported supplies via UAV from the SUNY hospital to a clinical laboratory, from the hospital to a separate surgery center, and from a pharmacy to another hospital in the area.
“We conducted 52 successful deliveries throughout the week and were able to streamline the process, getting to about five deliveries an hour,” Basile wrote in a NUAIR article he penned, titled, “Making Drone Deliveries Scalable and Economically Viable.”
The drone used during the NUAIR test flights was equipped with a parachute in case of a mechanical failure and was only flown late at night. Basile believes the FAA will likely require medical delivery drones to have six to eight motors (shown above) as a security measure in case one or two motors fail. A common type of drone, known as a quadcopter, has only four motors and it is unable to fly if even one motor fails. (Photo copyright: NUAIR.)
Although the unmanned delivery flights were successful, SUNY experienced challenges with using drones to make medical deliveries. Those challenges included:
Economics: The NUAIR test flights required five people to conduct the flights, which is more costly than paying one driver to deliver the supplies.
FAA restrictions: The FAA currently does not allow biohazardous materials or controlled substances to be transported by drones due to the risk of public exposure if a crash occurs.
Device approval: The FAA is still in the process of evaluating which drone models will be permitted to carry medical supplies.
Weather: Drones cannot fly in inclement weather conditions.
“[Drones] are susceptible to strong winds and icing,” Basile told GT.
However, Basile believes that with more research and test flights the challenges will be resolved, and that drones will be used for medical deliveries in the future.
“I think they’re certainly going to be used,” he told GT. “Whether it’s soon depends on what you mean by soon.”
Drones Deliver Clinical Laboratory Specimens and Medical Supplies Worldwide
Other countries are increasingly using drones to deliver COVID-19 test kits and samples to and from remote areas.
In 2018, Dark Daily reported on automated logistics company Zipline’s use of fixed-wing drones called “Zips” to provide on-demand access to vital blood supplies in Rwanda and Tanzania. The Silicon Valley company transported more than 5,500 units of blood in 2017 to 12 regional hospitals from a base in the east of Rwanda, reported The Guardian. Zipline began operating in the African nation in 2016 and quickly cut blood delivery time from four hours to an average of about 30 minutes.
And in “Swiss Post Medical Drone Carrying Clinical Laboratory Specimens Crashes in Switzerland,” we reported that the medical drone revolution experienced a setback when drone-pioneer Swiss Post (Switzerland’s postal service) saw one of its American-made Matternet drones crash into Lake Zurich, Switzerland. According to a Swiss Post news release, the drone went down carrying a “non-vital” blood sample (one that had been previously analyzed). The flight was part of a recently launched pilot program transporting blood samples between Zurich’s central laboratory and the Hirslanden Klinik Im Park, a private clinic on the opposite side of Lake Zurich.
Although not all drone delivery flights end in success, these projects clearly demonstrate how safe and reliable drone delivery of medical supplies and clinical laboratory specimens could one day be beneficial to medical communities.
Such drone deliveries will likely help medical professionals expedite diagnoses and treatment options for patients, especially in remote areas where land transportation would be much less timely.
Boston-based American Robotics is approved to operate its Scout unmanned aircraft in rural areas and below a certain altitude, achieving a milestone that may allow the industry to ‘truly take off’
Routine drone delivery of clinical laboratory specimens and medical supplies moved a step closer to reality with the Federal Aviation Administration’s (FAA) green light to American Robotics (AR) to operate its fully automated drones without on-site pilots or on-the-ground spotters.
The Massachusetts-based company becomes the first drone operator to receive an FAA Certificate of Waiver, allowing it to operate its unmanned aircraft “beyond the visual line of sight (BVLOS) of the remote pilot in command.”
According to a news release, “Prior waivers and certifications awarded by the FAA required visual observers (VOs) stationed along the flight path to keep eyes on the airspace at all times, or required other burdensome restrictions such as infrastructure masking. … With this approval, American Robotics’ Scout System is now the first drone technology allowed to continuously operate without this costly human requirement.”
The FAA is restricting American Robotics’ operations to specific rural areas and at altitudes below 400 feet, with a maximum takeoff weight of 20 pounds, The Hill reported. Nevertheless, should AR’s automated Scout System prove safe, pilotless drones may soon be delivering clinical laboratory specimens and supplies to remote areas as well as to more densely populated hospital systems.
The FAA’s Certificate of Waiver is effective until January 31, 2023.
A New Era of Drone Delivery for Hospitals and Clinical Laboratories
Even with the restrictions, the FAA’s decision moves the commercial drone industry ever closer to routine transport of medical laboratory specimens and medical supplies by unmanned aerial vehicles (UAV).
“With these approvals, American Robotics is ushering in a new era of widespread automated drone operations,” Reese Mozer, CEO and co-founder of American Robotics, said in the news release. “Decades’ worth of promise and projection are finally coming to fruition. We are proud to be the first company to meet the FAA’s comprehensive safety requirements, which had previously restricted the viability of drone use in the commercial sector.”
The Wall Street Journal (WSJ) reported that the FAA’s decision signals the agency’s “broader effort to authorize widespread flights by shifting away from case-by-case exemptions for specific vehicles performing specific tasks.” According to the WSJ, the FAA’s approval documents state that American Robotics’ proposed operations will provide the agency with “critical data for use in evaluating BVLOS [beyond the visual line of sight] operations from offsite locations.”
Each American Robotics Scout drone (above) is stored within a weatherproof base station that enables autonomous charging, data processing, analysis, and data transmission. According to the news release, “Once installed in the field, all facets of Scout’s operation are automated, allowing this technology to gather and analyze ultra-high-resolution data multiple times per day for years without expensive human labor.” Clinical laboratory managers will want to watch for progress in using drones to deliver medical supplies.

FAA Approval a ‘Game Changer’
In its quest to receive FAA approval, American Robotics completed a four-year testing program around its Scout line of UAV products. According to the company, Scout systems flew as many as 10 automated missions per day in 2020 for industrial and agricultural customers in multiple states capturing a variety of advanced data.
The Scout system addresses safety concerns by using acoustic detect-and-avoid technology to maintain a safe distance from other aircraft while also avoiding birds or other potential obstacles.
“The commercial drone industry is growing quickly and providing significant benefits to the American public, but enabling expanded operations beyond visual line of sight is critical for the industry to truly take off,” Lisa Ellman, JD, Partner at Hogan Lovells and Executive Director of the Commercial Drone Alliance, said in the news release.
“Automated beyond visual line of site operations are particularly important to opening the commercial sectors to the drone economy, including the agriculture and industrial verticals. Key to these operations is the use and FAA acceptance of new and innovative safety technologies, such as detect and avoid sensors and software-enabled automation.”
The agricultural and energy industries are seen as key beneficiaries of this latest FAA action. Lance Ruppert, Director of Agronomy Marketing and Technology at Growmark Inc., a leading US grower cooperative, calls the American Robotics’ approval a “game changer.”
“Our interest in American Robotics’ technology started with the desire to have a drone imagery solution that was reliable, scalable, and executed with minimal human resources,” Ruppert said in the news release. “This technology, along with the FAA approvals to operate it without humans on the ground, is key to making drones a widespread reality in our industry.”
Drone Delivery of Clinical Laboratory Specimens Worldwide
And past Dark Daily ebriefings reported on drone delivery of medical supplies being conducted in Virginia, North Carolina, Australia, Switzerland, and Rwanda. With potentially fully automated systems just around the corner, there’s no question the use of drones to transport critical medical supplies and biological specimens is poised for an amazing breakthrough.
While the FAA’s approval of the first fully automated commercial drone flights may not have an immediate impact on clinical laboratories, the increasing use of commercial drones brings drone transportation of lab specimens and other medical supplies one step closer to reality.
Onboard cooling system ensures samples remain viable for medical laboratory analysis after three-hour flight across Arizona desert
Clinical laboratories and anatomic pathology groups could soon be receiving blood samples and tissue specimens through the air by medical drone. The technology has been tested successfully in Europe, which Dark Daily reported in July. Now, Johns Hopkins University Medicine (JHUM) has set a record in America for the longest distance drone delivery of viable medical specimens.
In a project to demonstrate the viability of using drones to transport medical laboratory specimens, the Johns Hopkins University team flew a drone with specimens more than 161 miles across the Arizona desert. The goal is to bring autonomous medical delivery drones a step closer to transforming how specimens get transported across long distances, according to a Johns Hopkins press release.
A previous Johns Hopkins study in 2015 proved common and routine blood tests were not affected when medical laboratory specimens were transported in up to 40-minute flights on hobby-sized drones. This latest research provides evidence that unmanned aircraft may be able to successfully and quickly shuttle medical specimens even longer distances between remote hospitals and medical laboratories.
Transporting Clinical Laboratory Samples by Air Can Save Lives
In conducting its most recent study, Johns Hopkins researchers obtained paired chemistry and hematology samples from 21 adults (84 samples in total). One sample from each pair was held at a drone test range in a car with active cooling. Remaining samples were flown for three hours in a drone with a Johns Hopkins-designed onboard payload-cooling system to maintain temperature control in the hot desert environment.

After the 161-mile flight, all samples were transported 62 miles by car to the Mayo Clinic in Scottsdale, Ariz., for testing. Flown and not-flown paired samples showed similar results for red blood cell, white blood cell and platelet counts, and sodium levels, among other results. Only glucose and potassium levels revealed minor but statistically significant differences in results.
Pathologist Timothy Amukele, MD, PhD (above), led a team of researchers at Johns Hopkins University School of Medicine that set a new distance delivery record for medical drones after successfully transporting human blood samples 161 miles across the Arizona desert. The test flight adds to the growing evidence that unmanned aircraft may be the most effective way to quickly transport blood and other medical samples to clinical laboratories. (Photo copyright: Johns Hopkins Medicine.)
In a report of the findings published in the American Journal of Clinical Pathology (AJCP), the research team concludes that long drone flights at high temperature “do not appear to affect the accuracy of 17 of the 19 test types in this study.” However, they note, “Time- and temperature-sensitive analytes such as glucose and potassium will require good pre-planning and stringent environmental controls to ensure reliable results.”
The John Hopkins team believes their achievement adds to mounting evidence that drone transportation can transform the delivery of clinical laboratory specimens.
“We expect that in many cases, drone transport will be the quickest, safest, and most efficient option to deliver some biological samples to a laboratory from rural or urban settings,” stated Timothy Kien Amukele, MD, PhD, Assistant Professor of Pathology at Johns Hopkins University School of Medicine and the paper’s senior author, in a Johns Hopkins Magazine article.
“Getting diagnostic results far more quickly under difficult conditions will almost certainly improve care and save more lives,” Amukele added.
Full Drone Delivery Network Operating Over Switzerland
Medical drones are rapidly moving from demonstration projects to active use. As Dark Daily previously reported, Switzerland is establishing a delivery network of medical drones in the city of Lugano. In March 2017, drone logistics system developer Matternet, based in Menlo Park, Calif., received authorization from the Swiss Federal Office for Civil Aviation (FOCO) for full operation of drone logistics networks over densely populated areas in Switzerland. Working in partnership with Swiss Post (Switzerland’s postal service) and the Ticino EOC hospital group, Matternet successfully completed roughly 100 drone transport test flights between two of Ticino EOC’s hospitals in Lugano.
Another major player in medical drone delivery is Zipline, a Silicon Valley-based drone delivery company that since October 2016 has flown more than 14,000 flights in Rwanda, delivering 2,600 units of blood. The company’s foothold in Africa expanded in August when Tanzania announced it was partnering with Zipline to launch the “world’s largest drone delivery service to provide emergency on-demand access to critical and life-saving medicines.” Tanzania will establish four distribution centers that will use more than 100 drones to make up to 2,000 flights a day.
The emergence of medical drones not only could speed up diagnoses for patients in remote regions of the world and rural communities, but also could revolutionize anatomic pathology specimen deliveries to clinical laboratories in urban areas by providing a faster, more reliable and lower-cost delivery option than third-party couriers using ground transportation.
