I recently received a message from a local colleague who has received complaints from the nursing department when rejecting clotted coagulation specimens. The problem occurs with both citrated blue-closure and EDTA lavender-closure tubes. A few of the nurses are convinced the laboratory is storing the specimens too long before testing them, thus allowing them to become clotted. My colleague has provided in-services explaining the need for gentle specimen mixing immediately after collection, but has been only partially successful in convincing them that they control specimen integrity at the time of collection. I’d like to get responses from participants who face inter-departmental communication issues like this. How do you convince nurses and phlebotomists of the need to prevent hemolysis, short draws, and clotted specimens? Further, do you have any additional advice about managing pediatric specimens?
