What this trial studies

This study focuses on validating the accuracy and precision of drug assays that measure drug concentrations in various biological matrices using high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). It involves collecting samples from different bodily fluids to quantify levels of antimicrobials, antivirals, oral contraceptives, and erectile dysfunction agents. Additionally, samples will be collected from individuals not on these medications to ensure quality control of the assays.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals over 18 years of age who are either receiving or not receiving specific medications.

Not a fit: Patients who are unable to give informed consent will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the reliability of drug concentration measurements, leading to better patient management and treatment outcomes.

How similar studies have performed: While this approach is essential for ensuring assay accuracy, similar studies have shown varying degrees of success in validating drug measurement methods.
