Test ID: CH8    
Chromogenic Factor VIII Activity Assay, Plasma

Useful For Suggests clinical disorders or settings where the test may be helpful

Monitoring coagulation factor replacement therapy of selected extended half-life coagulation factor replacements

 

Aiding in the diagnosis of hemophilia A using a 2-stage assay, especially when the 1-stage assay was normal

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

This assay is indicated in situations where there is a clinical suspicion of hemophilia A diagnosis, but the 1-stage FVIII assay is normal. However, recent guidelines also recommend this assay be performed in addition to the 1-stage assay in the initial workup of hemophilia A.

 

Coagulation testing is highly complex, often requiring the performance of multiple assays and correlation with clinical information. For that reason, we recommend requesting a coagulation consultation.
