C4 Test - More Information
The C4 blood test, also known as a C4 lab test and a complement component C4c test, measures the C4 blood level.
Complement C4 is a part of a portion of the immune system known as the complement system. Abnormal levels of C4 can be associated with autoimmune conditions like glomerulonephritis, systemic lupus erythematosis (SLE), cryoglobulinemia, or another autoimmune condition. To get a C4 blood test near you, just order online and get your blood drawn at the selected Quest Diagnostics location. Once your C4 lab report is ready, it will be available for download. As can be seen on the sample C4 lab report above, the C4 blood levels are reported as a number and can be compared against the reference ranges provided by the lab.
The complement C4 lab test is part of the lupus test panel.
