Episode 2 - In the Lab: PT and aPTT

Bloody Minded

It is a truth universally acknowledged that a JMO in possession of a coagulation tube will underfill it. But why should it matter?! In this episode, we review the principles behind the two most important coagulation screening tests (The PT and the aPTT) as well as follow the journey of that precious citrated sample through the lab. By the end, you’ll know enough to at least feel guilty when you still send that half filled tube down the chute at 3am
