The levels of a specific type of protein in your blood, C3 proteins, are measured by a C3 test. C3 proteins, a part of your immune system, kill germs (microbes) that can make you sick. Occasionally, C3 proteins erroneously launch an attack on healthy cells. Your healthcare provider will receive information regarding the functioning of your immune system based on the results of this blood test. Your doctor can diagnose infection, immune deficiency, disease, and other health conditions by measuring the amount of C3 proteins in your system. Additionally, this test assists your healthcare provider in monitoring your autoimmune disease treatment.
The complementary immune system includes C3. Based on whether C3 values are high or low, the C3 test provides information about the state of your immune system. The complementary immune system is a component of the larger innate immune system, which acts as the body’s primary line of defense against disease. It can reveal whether you have an autoimmune disease that causes the body to attack its cells or tissues or a specific immune deficiency that puts you at risk of infection. C3 proteins can also rise or fall in response to certain infections and diseases, such as liver and kidney disease. Additionally, the test can determine whether an autoimmune disorder treatment is effective. The purpose of a C3 complement test and the reasons your healthcare provider might order one are discussed in this article. If you need to take the test, it also explains what to expect and what the results mean.

When do you need to take a C3 test?
A C3 complement test may be ordered if you show any signs or symptoms of certain infections or diseases. It may include the following reasons:
- Your healthcare provider may order a test if you have recurring bacterial infections.
- In addition, you are exhibiting symptoms of lupus-like autoimmune disease.
- You have unexplained swelling or inflammation, and your doctor wants to see if you respond to autoimmune disease treatments.
Although it cannot make a medical diagnosis, the C3 complement test can be used with other tests to narrow or confirm the possible causes.
What does the C3 test include?
A straightforward blood draw is required for the C3 complement test. No special preparation is needed for this test. You can have it done at a lab, a hospital, or a clinic. The average cost of this test is between Rs. 350 and Rs. 1000.
Waiting times for the test may vary at the clinic. The actual blood draw only takes a few minutes. You can also inquire about an anticipated wait time in advance by calling the clinic or lab. There are no food, drink, or drug limitations associated with a C3 supplement test. If you are having other tests at the same time, ask your doctor if you need to fast or change your medication.
What to expect during a C3 test?
You will be directed to a room where your blood will be drawn after signing a consent form and checking in with the receptionist. A phlebotomist, a nurse, or a technician with special training in blood draws will collect the blood sample. Once you’re seated, you’ll be prompted to select the arm from which you want your blood drawn. The next set of steps includes —
- Your forearm is bandaged with a tourniquet, a tight elastic band. To select the best vein, the nurse will touch the crook of your arm.
- Using an alcohol swab, the skin will be cleaned. Then, to obtain blood, a special tube or syringe with a needle will be inserted into the vein.
- Although there may be a slight sting, there is typically no severe pain.
- The tourniquet is removed, and the needle is removed once sufficient blood has been obtained.
A protein called C3, a component of the body’s immune response, is measured with a C3 test. Infections, autoimmune diseases, immune disorders, chronic kidney or liver disease, and values that are high or low may all be signs of medical issues. The test is a straightforward blood draw combined with other tests to narrow down the possible causes. Additional tests may be ordered by the doctor if an abnormal result is returned.
