Researchers Double-Check drug measurement methods
NCT ID NCT02283112
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study checks whether lab tests that measure drug levels in body fluids are accurate and reliable. Researchers will collect blood, urine, and other samples from 100 adults who are taking certain medicines (like antibiotics, antivirals, birth control, or erectile dysfunction drugs) and from people not taking those medicines. The goal is to improve the quality of future drug studies, not to treat any condition.
