Every driver involved has been trained in handling medical material, Amazon told CNBC. The tests revolve around the familiar swabs used at drive-through testing locations. If a recipient tests positive, healthcare workers will get in touch.

Amazon Care director Kristen Helton said in a statement that the company knows fighting COVID-19 will require help from “both the public and private sectors,” and was “eager to leverage” Care’s resources to back a local effort.

This isn’t a full-fledged testing system, and it’s not guaranteed to expand further. However, it could show how Amazon and other companies could improve access to testing at time when it’s critically low. Amazon also has a vested interest in accurately diagnosing and fighting the spread of COVID-19. Washington state has been particularly hard-hit by the virus, with over 1,000 cases and 75 deaths in King County (which includes Amazon’s Seattle home) as of this writing. Improved research and testing could help keep employees and the broader community safe.

At this stage, however, the service is intended only for Amazon’s own employees, and joins pilot program Amazon Care, which acts as a medical benefit for staff. If employees are unwell they can use the service to access virtual care through a video consultation, or obtain a home visit if necessary. PillPack, which provides prescription delivery, also falls under the Amazon Care umbrella.

With around a dozen employees, Health Navigator is considerably smaller than PillPack, for which Amazon paid $753 million last year. The exact details of the new acquisition haven’t yet been disclosed, although CNBC reports that Health Navigator does not plan on renewing its contracts with existing customers.

Although the move is primarily focused on internal benefit right now, it does provide another hint as to Amazon’s longer-term, more commercial aspirations within the healthcare field. Last year the company announced a partnership with Warren Buffet and JPMorgan Chase that aims to create healthcare solutions that benefit “potentially all Americans.” The acquisition of Health Navigator is likely a stepping stone in achieving that goal.
