Factor X (Stuart-Prower) Clotting Activity Test

Vermont rates for HCPCS 85260

Measures how well clotting factor X, also called Stuart-Prower factor, is working in a blood sample. Factor X sits at the point where the two arms of the clotting cascade meet, so a shortage lengthens standard clotting times and shows up as easy bruising and bleeding. It is checked when clotting screens come back abnormal and the specific protein at fault needs pinning down, or to follow a known factor X deficiency.
