Question

Quizplus · Accepted Answer

Heparin can interfere with certain tests, such as heparin-induced platelet aggregation and heparin assay. If the test cannot be run promptly, the heparin in the sample may continue to interfere with the test. Additionally, if the heparin salt that was used to collect the sample contains the substance being measured, it can also interfere with the test. Therefore, samples collected with heparin anticoagulant are unsuitable for analysis when either of these situations occur, as stated in choices A and C.
