Abstract
BACKGROUND: Platelet function analysis is crucial in assessing the hemostatic status to evaluate congenital and acquired platelet function defects. The Anysis-200 analyzer is a new automated lab-on-a-chip-based platelet function analyzer. OBJECTIVE: We aimed to evaluate a new platelet function analyzing system, the Anysis-200 in comparison to the Platelet Function Analyzer (PFA)-200 in cardiac patients. METHODS: Citrated blood was collected from 174 patients who visited the Department of Cardiology. The Anysis-200 consists of two kits, the microchips with collagen and epinephrine-coated membrane (C/EPI) or adenosine diphosphate-coated membrane (C/ADP). Platelet clogging in the Anysis-200 is measured by the blood migration distance obtained by a camera, which is compatible with the closure time in the PFA-200. We performed Anysis-200 and PFA-200 analyzers simultaneously and compared the results. RESULTS: The sensitivity and specificity of the Anysis-200 C/EPI kit in comparison to the PFA-200 C/EPI kit were 63.41% and 91.43%, respectively. Regarding the C/ADP kit, the sensitivity and specificity of the Anysis-200 were 58.97% and 74.29%, respectively. The agreement rate between the Anysis-200 and PFA-200 for C/EPI was 83.35% and 70.14% for C/ADP. CONCLUSIONS: The Anysis-200, which applies a novel method to detect platelet clogging, has shown moderate to fair agreement with the PFA-200. This test is potentially useful for screening cardiac patients with an abnormal platelet function.
