For current space flight missions, NASA has the ability to return blood and urine samples to the ground for testing and evaluation. For long-duration space missions, it will not be possible for ground testing of these flight samples. There is a need to evaluate if Commercial-Off-the-Shelf (COTS) medical devices capable of assaying biologic fluids will function correctly in microgravity.

The rHealth ONE platform will be certified for flight using the International Space Station (ISS) COTS process. The vendor will perform minor modifications to the device to conform to flight certification requirements and to ensure ease of use for the crew (simpler fluid capture/containment and minimal user interaction). The flight device will demonstrate detection of a variety of relevant particulate matter in a control solution that is representative of blood cells and rHEALTH’s proprietary nanostrips for soluble analytes. Those flight measurements will be compared to ground measurements taken of the same batched control solution. It is expected that the on-orbit demonstration will show that the rHealth ONE operates nominally in the microgravity environment.
This study is in progress. Results will be available at a later date.
