Artifactual shortening of prothrombin time in a semi-automated coagulometer because of lipaemic plasma.
Widespread use of coagulometers over the past few decades has improved the accuracy and precision of coagulation tests. However, test results even from sophisticated coagulometers are prone to errors due to both analytical and pre-analytical factors. Coagulometers utilizing absorbance variation for end point detection can generate erroneous results due to turbidity in the test plasma. We present a case with artifactual shortening of prothrombin time because of lipaemic plasma.
