Understanding Low Molecular Weight Heparin and its Impact on Anticoagulation Testing

 “Have you not done tormenting me with your accursed time?“ Senior scientists Vladimir and Estragon are waiting quite a while for a clot to form in their tube. How should you react to prolonged clotting times? We cover an approach to prolonged PT and aPTT, as well as discuss the mechanism of common anticoagulants and their impact on these basic tests.
