Antithrombin III

Antithrombin III is a blood test that measures the amount of antithrombin III (AT III), a protein that helps control blood clotting.

Antithrombin III is a protein in the blood that naturally blocks blood clots from forming. Congenital antithrombin III deficiency is an inherited disease. It occurs when a person receives one abnormal copy of a gene from a parent with the disease.

A complete blood count (CBC) accompanied by coagulation tests such as prothrombin time (PT), partial thromboplastin time (PTT), and antithrombin III, are done to evaluate hematologic diseases and risk for thromboembolism.

Other blood tests may be normal, but levels of Antithrombin III (measures risk for clot formation) may provide valuable information.

There are a number of conditions that make clots in the veins more likely, for example deficiencies of proteins C, S, antithrombin III, Factor V Leiden mutation and antiphospholipid antibodies.

Mutated genes (such as factor V Leiden, factor II).
Decreased amounts of certain proteins (protein C, protein S, and antithrombin III).
Increased levels of other substances (antiphospholipid or lupus anticoagulant).

Common mutations include Factor V Leiden and Prothrombin G20210A mutations. Fairly rare genetic mutations include proteins C and S deficiencies and antithrombin III deficiency.
