The Accuracy Performance of the Point of Care Test (POCT) Boditech I-CHROMA™ Testosterone Method using External Quality Assessment Schemes: RIQAS and UKNEQAS | Biomedgrid

The estimation of testosterone levels in the blood is an important part of urological practice. This study evaluated and compared the performance of the quantitative Boditech point of care test Boditech i-CHROMA™ testosterone method with other laboratory testosterone methods enrolled in the external quality assurance services, RIQAS and UKNEQAS. Samples 1-12 of Cycle 41 from the RIQAS scheme and forty-six distributions of the UKNEQAS Testosterone scheme were analyzed using the Boditech i-CHROMA™ testosterone method. The Boditech i-CHROMA™ testosterone method compared well with the laboratory methods registered in both schemes. The best correlation was with the Diasorin Liaison method (r2=0.96851) in the RIQAS and the TOSOH AIA method (r2=0.767) in the UKNEQAS. The method with the least bias from the RIQAS was the Diasorin Liaison (-2 ng/ mL) and from the UKNEQAS was the Tandem Mass Spectroscopy (0.049 ng/mL). In conclusion, the Boditech i-CHROMA™ POCT Testosterone method compared well with other laboratory methods and can be considered a reliable method for testosterone estimation within its limitations.
