Summary

This study tested whether a quick fingerstick blood test for D-Dimer (clot marker) and CRP (inflammation marker) gives the same results as standard lab tests using blood from a vein. Researchers enrolled 111 adults and compared results from fingerstick, venous whole blood, and plasma samples. The goal is to see if these point-of-care tests can reliably help doctors diagnose conditions like blood clots or infections faster.
