Intended use

The C1-Inhibitor assay measures the amount of functional C1 inhibitor protein (C1-INH) in human plasma or serum. This protease inhibitor has enzyme regulating functions. A deficiency of functionally active C1-INH may lead to life-threatening angioedema. Two major forms of C1-INH deficiency have been reported: the congenital form, termed hereditary angioedema (HAE), and the acquired form, which is associated with a variety of diseases including lymphoid malignancies. Hereditary angioedema is characterized by transient but recurrent attacks of nonpruritic swelling of various tissues throughout the body.
