Question

Quizplus · Accepted Answer

Heparin contamination can interfere with coagulation testing, so care must be taken when drawing blood from catheters or other devices that may have been flushed with heparin. The tube for coagulation testing should be the second or third tube drawn, after the tubes for other tests to minimize the risk of contamination. It is also important to fill the sodium citrate tube to the proper fill line and not underfill, as this can affect the test results. Butterfly needles can be used for coagulation testing as long as they are the appropriate size and the healthcare provider is properly trained in their use.
