Abstract
Automated coagulation analyzers have replaced manual methods to meet the everincreasing test load in many laboratories Of the different methods two distinct methods exist based on optical and mechanical clot detection magnetic steel ball method In optical method the detection of clot formation is measured by a change in optical density OD of a test sample Mechanical clot detection technology involves monitoring the movement of a steel ball within the test solution using a magnetic sensor There are limited studies comparing both these methods and they have conflicting results regarding the effect of plasma turbidity on the final result We report a case where a plasma factor lipemia caused prolongation of both PT and APTT as measured by the photo optical method
