Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective is to demonstrate the performances of STA® - Apixaban Calibrator \& STA® - Apixaban Control used in combination with STA® - Liquid Anti-Xa to measure apixaban concentration in plasma. Anti-Xa results will be compared to LCMS (liquid chromatography - mass spectrometry) for validation of the assay. For this study, the anti-Xa assay will be performed on fresh samples only.

The results will be used to complete results obtained previously on frozen samples.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

About 60 samples from patients on apixaban meeting inclusion/exclusion criteria will be included in this study. Two sites will be in charge of sample recruitment and anti-Xa testing. A third site will be in charge of LCMS testing.
