Clot Dissolving Time Test

Maryland rates for HCPCS 85175

A laboratory test in which a clot is formed from a diluted whole blood sample and timed to see how long it takes to break apart. A clot that dissolves unusually fast points to an overactive clot-breakdown system, which can explain bleeding that has no other obvious cause. It is a timed observation rather than a measurement of any single clotting factor.
