Frequent contributor Dave McGlasson called from the American Society for Clinical Laboratory Science annual meeting venue in San Diego. He has just heard this question from a colleague. "Can you use the chromogenic anti-Xa heparin assay when the specimen is hemolyzed or icteric?" Her concern arose from cases in which patients had been treated with Alteplase (TPA ), causing hemolysis, and now there was an immediate need to measure the unfractionated heparin level to guide reversal.
