Summary

This trial tests a new way to measure how well blood-thinning medication is working in people who are obese.

Who is the study for?
This trial is for adults over 18 who are healthy or severely obese (BMI <30 or ≥35 kg/m2), with normal kidney function, blood platelet count, and hematocrit levels. It's not for pregnant women, those with recent drug use that affects blood clotting, major illness/surgery history, gastrointestinal bleeds/ulcers, hemorrhagic stroke history, or bleeding disorders.
What is being tested?
The study tests a new platelet activity assay against the standard test by measuring responses to aspirin and clopidogrel in volunteers. It aims to determine the accuracy of this novel assay and refine its parameters compared to traditional methods.
What are the potential side effects?
Aspirin and Clopidogrel can cause side effects like increased risk of bleeding, bruising easily, upset stomachs or heartburn. Serious but rare side effects include severe bleeding or allergic reactions.
