NCT ID NCT04822363

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tested a new blood test (pDrp1 assay) to measure platelet activity in 112 healthy and severely obese volunteers taking aspirin or clopidogrel. The goal was to see if the new test is as accurate as the current standard test (light transmission aggregometry). Researchers also looked at how the drugs work over time. The study is complete, but results are not yet reported.

What this could lead to

If successful, this could provide a simpler, faster blood test to measure how well antiplatelet drugs work, helping doctors tailor treatments.
