The TEG (Thromboelastogram)

Editor’s Note: Recently we began employing the TEG routinely for all of our open-heart procedures.  Now I am relatively familiar with the concept, having discussed and written about it before.  However there is an array of numbers and categories that come with the TEG analysis that I wasn’t certain about, so to clear it up […]

Hemostasis Assays [v.1]

Partial Thromboplastin Time (Activated) The activated partial thromboplastin time (aPTT) is test that overlaps the prothrombin time (both evaluate the common pathway), and is designed to isolate the intrinsic pathway.  While these tests are similar, the aPTT utilizes kaolin or cellite and cephaloplastin to stimulate the intrinsic pathway.  This pathway is the longer of the […]
