Factor X Inhibitor Profile, Technical Interpretation
Use
This test provides a technical interpretation of inhibitor to coagulation factor X testing. Coagulation factor inhibitors can arise in patients congenitally deficient in a specific factor in response to replacement therapy, spontaneously, or in response to conditions such as postpartum state, immunologic disorders, certain antibiotics, malignancies, and advanced age. It evaluates the presence or absence of a factor X inhibitor through interpretive comments based on factor activity results.
