title: Measurements of some blood clotting factors using a centrifugal analyser (Multistat III).
abstract: Three coagulation tests are performed on a centrifugal analyser (Multistat III) and the results are compared with results from an ordinary coagulometer (Fibromat). The three tests are Quick's prothrombin time, prothrombin and proconvertin method (Owren's P & P) and activated partial thromboplastin time test (aPTT). The coefficients of correlation for the three methods between the two analysing systems are better than 0.90. The standard deviations of the three analyses are better than 0.60 sec on the centrifugal analyser compared to 1-2 sec on the coagulometer. The centrifugal analyser can perform up to 120 samples per hour.
