C4 (Complement Level 4)
Over the last 5 Years we made an impact that is strong & we have long way to go.
The C4 (complement component 4) test measures the level of C4 protein in the blood. C4 is another key component of the complement system, a group of proteins in the blood that plays an essential role in the immune system by promoting inflammation, defending against infections, and clearing damaged cells. C4 works along with other complement proteins, such as C3, to help destroy pathogens and modulate immune responses.
