Abstract
- INTRODUCTION In the developing world, point-of-care (POC) testing for international normalized ratio (INR) plays an important role in the monitoring of patients on long-term warfarin therapy with limited access to healthcare ensuring safe and effective anticoagulation. A newly developed POC device for INR measurement by healthcare workers is the handheld qLabs POC device® (Micropoint Biotechnologies Incorporated, Guangdong, China). METHODS The qLabs POC device® was evaluated in 262 patients attending an anticoagulation clinic with regards to accuracy and precision of the INR results. The results were compared to the results obtained on the Stago STA R Max® coagulation analyzer (Stago Diagnostica, Paris, France) on a wide range of normal and abnormal results of clinical relevance. RESULTS The mean laboratory INR (2.50 ± 1.08) was significantly higher than the qLabs POC device® INR (2.38 ± 1.07) (P 3.5). The imprecision was within acceptable limits (
