Heparin unfractionated [Units/volume] in Blood by Heparin protamine titration
Active
Term 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.

Part Descriptions
LP16002-5 Heparin.unfractionated
Heparin is a highly sulfated glycosaminoglycan widely used as an injectable anticoagulant. It is also used to form an inner anticoagulant surface on various experimental and medical devices such as test tubes and renal dialysis machines. Pharmaceutical grade heparin is commonly derived from mucosal tissues of slaughtered meat animals such as porcine intestine or bovine lung.

LP16002-5 Heparin.unfractionated
A highly acidic mucopolysaccharide formed of equal parts of sulfated D-glucosamine and D-glucuronic acid with sulfaminic bridges. The molecular weight ranges from six to twenty thousand. Heparin occurs in and is obtained from liver, lung, mast cells, etc., of vertebrates. Its function is unknown, but it is used to prevent blood clotting in vivo and vitro, in the form of many different salts.
