About Complement (C3, C4) Test

Why is the Complement (C3, C4) test done?

The complement system or complement cascade is an essential part of the immune system. Complement proteins play a vital role in helping the immune system prepare antibodies that will counter the foreign antigen.

The complement (c3, c4) test is done to check if the person is suffering from any autoimmune disorders or inflammatory disorders. This test is also done to check if the complement system has any issues that restrict it from preventing infections. This test is collectively known as total complement activity (CH50, CH100). It is also used to detect lupus in a person.

Symptoms that prompt a doctor to prescribe the complement test are:

  • Recurrent infections, especially bacterial infections
  • Sudden inflammations
  • Edema
  • Fever
  • Inflammation of joints
  • Joint ache
  • Lymph nodes appear to be swollen
  • Pain in the chest, especially when taking in deeper breaths
  • Sore mouth
What does the Complement (C3, C4) test measure?

The complement (c3, c4) test, as the name mentions, measures the proteins C3 and C4. Both these complement proteins are associated with helping detect lupus. The complement proteins play a role in matching the specific antibodies for the antigens detected. C3 is the most abundant complement protein in the system. This protein plays a major role in helping the immunity pathways create proteins to counter the infection. In fact, the activation of this C3 protein initiates the pathways.

Abnormalities in the results can mean that the person is suffering from conditions that can be autoimmune or inflammatory in nature. This test is also used as a monitoring test to check the effectiveness of the treatment chosen.

Potential risks/side effects associated with the Complement (C3, C4) test

The complement protein blood test is done by checking the blood samples collected from the person. There are no known life-threatening risks or side effects associated with this test. Sample collection is done by experienced phlebotomists and the collected samples are immediately sealed in a vacutainer.

The process of drawing blood involves the insertion of the needle into the subdermal layer to reach the vein. This can cause some discomfort to the person. At times, this insertion and extraction causes bruising. These go away soon. People having a lower blood count can feel dizzy and nauseous. For such instances, taking rest and adequate vitamin supplements are suggested.

Ms Sujata arrived on time and was very polite and caring throughout the process. Actually there was a mistake on my part where I couldn't attend her calls because I was not well and i feel asleep bcoz of my medicines. I had scheduled an appointment for my mother but Ms Sujata somehow reached my address by asking my neighbours. Such a lovely girl, and also the collection process was really smooth. Would absolutely recommend everyone to check out their services
