Webto APTT ratio (derived from mean normal APTT): COVID-19 1.65 and VITT 1.48. The plasma drug concentration quanti fied by dTT had a mean of 0.64 µg/ml in COVID-19 and 0.53 µg/ml in VITT. Poor correlations were seen in both methodsfor deriving APTT ratio when compared to dTT COVID-19 baseline APTT ratio r2=0.1526 p <0.0001, mean … WebReduced procoagulant concentrations result in prolongation of baseline coagulation variables, particularly the activated partial thromboplastin time (APTT), and it is therefore very important that results are interpreted in conjunction with age adjusted normal ranges.
