Complement Component Activity Test

Georgia rates for HCPCS 86161

This blood test measures the functional activity of one specific protein within the complement system, a group of immune proteins that normally work together to fight infection and clear damaged cells. It is used to help investigate certain autoimmune diseases, recurrent infections, or unexplained inflammation. A low result can indicate that this particular protein is being used up faster than it can be replaced, or that a person was born with a shortage of it.
