What is the normal range for APTT?

The activated partial thromboplastin time (APTT) is a crucial laboratory test that evaluates the intrinsic and common pathways of coagulation, helping to assess the efficacy of the blood coagulation process. The normal range for APTT is typically between 24 and 32 seconds, which indicates how well the blood can clot.

When the APTT is within this range, it suggests that the patient has a normal coagulation profile for the factors assessed by this test, making it an essential component of preoperative evaluations and monitoring patients on anticoagulant therapies. Values that fall outside of this range may indicate either a bleeding disorder or an increased risk of thrombosis, thus making it imperative for healthcare providers to understand and interpret these results accurately in the context of patient care.
