Core Lab - Coagulation

The routine and Special Coagulation Laboratories at the Children’s Hospital of Philadelphia provide comprehensive diagnostic testing for patients with bleeding and thrombotic disorders with a full menu of specialized and routine evaluations. We were among the first in the nation to offer chromogenic Factor VIII inhibitor assays for patients on emicizumab. We have a dedicated and skilled staff with specialized concentration in coagulation testing and many of our assays are available with turn-around times of 72 hours or less (STAT testing can also be arranged by calling the special coagulation laboratory at 215-590-1778). In addition to our routine coagulation assays such as PT/INR, PTT, Fibrinogen, D-Dimer, unfractionated and low molecular weight heparin Anti-Xa, and VerifyNow, which are offered on a 24 x 7 basis, we offer a variety of special coagulation assays listed below:
