Functional Testing

Functional testing is used to determine whether or not a specific substance is properly performing its biological role in the body and to what extent. This testing can determine how well a specific coagulation factor is performing its role in the coagulation cascade; for example, normal amounts of fibrinogen can be present, but if not working properly, abnormal coagulation results. Functional testing can also determine the correct level of activity of other substances such as hormones and enzymes.
