LOINC long common name : Heparin unfractionated [Units/volume] in Blood by Heparin protamine titration;
LOINC short name : UFH Bld HPT-aCnc;
LOINC description : The heparin assay measures the patient's actual circulating concentration of unfractionated
heparin in a sample of fresh whole blood by using titration with known quantities
of protamine in individual assay channels. The channel whose quantity of protamine
neutralizes the heparin in the test sample will have the shortest clotting time, and
the concentration of heparin is calculated based on the known amount of protamine
in that channel. The heparin concentration is used along with the activated clotting
time in the cardiac OR to give a more complete picture of the patient's heparin anti-coagulation
status. Using this test, the clinician/perfusionist knows how much heparin is present,
and how much additional heparin is needed during the procedure, and the amount of
protamine sulfate that is required to reverse the remaining heparin in the patient
at the end of the procedure. This term was created for, but not limited in use to,
the submitter's Medtronic HMS Heparin Assay test kit.;
