Clotting-regulation Protein Blood Test

Connecticut rates for HCPCS 85303

This is a blood test that checks one of the body's natural proteins that help keep blood clotting in balance. It's typically ordered as part of a work-up for someone who has had an unexplained or recurrent blood clot, to see whether a deficiency in this protein might be contributing. It's usually run alongside related tests looking at other clot-regulating proteins.
