Both tests may be helpful in the diagnosis of hereditary angioedema (HAE). The resultant over-stimulation of this system leads to the production of inflammatory anaphylatoxins, which affects the flow of body fluids between the vascular system and body tissues. 48494-9. Genetic and acquired forms of C1-INH are associated with the syndrome of hereditary angioneurotic edema, which consists of recurrent bouts of noninflammatory swelling involving the subcutaneous tissues, intestinal walls, airways, and lungs. This assay is very sensitive to sample handling and storage conditions. C1 esterase inhibitor deficiency results in hereditary angioedema. Another … The C1 Inhibitor, Functional test (test code 297) measures the relative functionality of an individual’s C1 esterase inhibitor protein using an enzyme immunoassay. Because 15% of C1 inhibitor deficiencies have nonfunctional protein, some patients will have abnormal functional results (FC1EQ / C1 Esterase Inhibitor, Functional Assay, Serum) in the presence of normal (or elevated) antigen levels. Diagnosing hereditary angioedema and for monitoring response to therapy. Patient serum is mixed with C1 inhibitor (C1-INH) reactant (biotinylated, activated C1s). FDA or Other Governmental Regulatory Approval U.S. Food and Drug Administration (FDA) Berinert is a C1 esterase inhibitor approved by the FDA in 2009. Acquired C1 inhibitor deficiency may occur with B-cell lymphomas and some autoimmune diseases. Test Name. View/Edit Mouse. C1-inhibitor (C1-inh, C1 esterase inhibitor) is a protease inhibitor belonging to the serpin superfamily. Its main function is the inhibition of the complement system to prevent spontaneous activation. This is a trend that has frequently been referred to as 'the epidemic of the 21st century'.
