PATHFAST hsCRP is a chemiluminescent enzyme immunoassay (CLEIA) for in-vitro diagnostic use with the in vitro diagnostic system PATHFAST for the quantitative measurement of C-reactive protein (CRP) in human serum, heparinized or EDTA whole blood and plasma, also at low concentrations. By loading PATHFAST hsCRP into the in vitro diagnostic system PATHFAST, CRP can be accurately quantified within 17 minutes, enabling safe diagnosis on-site for patients with acute coronary syndrome, suspected coronary heart insufficiency, venous thromboembolism, inflammation and myocardial injury.
