This system consists of a group of proteins that work with the immune system to identify and fight pathogens such as germs and bacteria.
There are nine important complement proteins. They are called C1 through C9. Complementary proteins may be measured individually or together. Proteins C3 and C4 are considered the most tested individual proteins. complement The CH50 test (sometimes called CH100) determines the abundance and output of all important proteins. complement proteins.
