Term Description

Functional C1 esterase inhibitor is reported as % means "percent of functional over mean normal" by many commonly used kits. This is reported by LOINC code 48494-9. Many sites have incorrectly mapped to [LOINC: 10634-4] (functional /Total) which is not the component reported by the commonly used methods.

Part Description

LP14796-4   Complement C1 esterase inhibitor.functional
The C1 esterase inhibitor assay is used to diagnose hereditary angioneurotic edema. Exhaustion of C1 esterase inhibitor allows spontaneous auto-catalytic C1 activation and the break down of C2 and C components. The disease can be caused by low concentrations or the abnormal structure of the protein. The disease is inherited as an autosomal dominant trait and has been successfully treated with prednisolone and transfusion of fresh frozen plasma. Source: Regenstrief Institute
