A member asked:
What would having low complement levels indicate?
A doctor has provided 1 answer
Low complement: Low levels of complement are seen in persons with complement deficiency who are prone to recurrent infections as well as in certain autoimmune conditions, inherited angioedema conditions, and hives associated with vasculitis (inflammed blood vessels). These can all be serious. Collection of blood to measure complement is tricky and needs to be done right or low level could occur.
