5 M Urea for Factor XIII

From Pam Owens: Hi George, good to see you at THSNA! (Thrombosis and Hemostasis Summit of North America). I am hearing more about how ineffective the 5M urea test is for factor XIII screening and am thinking we just need to stop doing the assay in our lab. I’ll need to convince our lab director. Are there any articles or published […]

TEG for LMWH?

While attending the American Society for Clinical Laboratory Science (ASCLS)-Michigan annual meeting in Kalamazoo, I met Beth Friedt, MSA, MT (ASCP), Administrative Director of the Clinical Laboratory at Hurley Medical Center, Flint, Michigan. She asked if thromboelastography (TEG) or thromboelastometry (TEM) has been used to measure low molecular weight heparin (LMWH) therapy. I knew of no instance where it was […]

Here is a note from the American Society for Clinical Laboratory Science Consumer Web Forum: What is the normal value of D-dimer in pleural or peritoneal fluids. I know the normal range of D-dimer in the blood is less than 250 ng/mL D-Dimer Units but what about other body fluids? Thank you. I have found no reference to […]

Anti-Xa to Replace PTT

From frequent contributor, Kim Kinney: Hi George, our Indiana University Health Pathology Laboratory is thinking of making the push again to use the Anti-Xa to monitor unfractionated (UFH) heparin therapy in place of the activated partial thromboplastin time (aPTT). I would like to hear from institutions that have made the transition successfully even in light of […]

Mixing Studies on Minimally Prolonged PTs and PTTs

I pose this question to see what others are doing in this scenario and what literature there is to support your practice. We commonly get mixing study requests in which the PT or PTT are just minimally out of our normal range, such as 0.1 seconds outside for PT. Is this 0.1 second enough to […]

Using the PTT After Cardiac Catheterization

This question was forwarded by an American Society for Clinical Laboratory Science Consumer Web Forum volunteer: Our hospital currently uses activated clotting time (ACT) results during heart catheterizations to monitor heparin dosage. The ACT is also used as a guide for pulling the sheath. The nurse confirms that the ACT is less than a certain […]
