Agnirva Space Premier League - Expedition #31788: Diagnosing Health in Orbit: Testing an Onboard Diagnostic Kit on the ISS

Imagine being a doctor, but your patient is 400 kilometers above Earth aboard the International Space Station (ISS). You can't perform a house call, and there’s no hospital nearby—only the onboard equipment and the astronaut’s training to keep them safe. This scenario underscores the importance of a reliable onboard diagnostic kit, and that’s exactly what the experiment 'Evaluation of Onboard Diagnostic Kit' set out to test.

Led by Yoshinori Yoshimura from Tsukuba Space Center and backed by the Japan Aerospace Exploration Agency (JAXA), this project evaluated a compact, easy-to-use diagnostic tool onboard the ISS. The goal was to determine whether such a kit could function in microgravity, providing astronauts with rapid assessments of their health.

The key challenge in space healthcare is autonomy. With communication delays and limited medical support, astronauts must often handle medical issues on their own. This kit, designed for microgravity, offers a way to run essential diagnostic tests, potentially including blood analysis, infection detection, and more.

During Expeditions 27/28, 31/32, and 33/34, astronauts tested this diagnostic device under real space conditions. The findings informed not only space missions but also influenced telemedicine and healthcare technologies on Earth—particularly in remote or inaccessible areas where medical professionals are scarce.

Ultimately, the success of such diagnostic tools paves the way for longer missions, including lunar bases and Mars expeditions, where medical independence will be paramount.
