The Complement Component C4a Plasma Test test contains 1 test with 1 biomarker .

Complement Component C4a, Plasma - During activation of the classical or lectin pathway of complement, C4 is cleaved into C4a and C4b. C4a is rapidly cleaved to the more stable form C4a-des-arg. Even if total C3 and C4 levels are not low (because of increased production by the liver during acute inflammation), elevated levels of C4a-des-arg indicate recent complement pathway activation
