C4 levels are just one of the complement measures that are looked at. Like any routine blood test, a vein in the arm is selected, the skin overlying it is cleaned with antiseptic and the required amount of blood is taken out using a syringe. C4, another protein of the complement system, showed a similar correlation with disease activity and prognostic scores. The complement system is a group of proteins that move freely through your bloodstream.

C 3 comprises 70% of total complement protein and also has alternative pathways. C3 medical blood test is used for the quantitative determination of serum complement C3. Correlation coefficients between C3 and C4 concentrations and metabolic variables. This blood test measures component 3 (C3) of the complement system. Complement C3 is a blood test that measures the activity of a certain protein that is part of the complement system. The complement system comprises of more than 30 proteins in the blood, that play a significant role in the body's immune system.
