C3 Protein Test

Three reasons the Complement C3 test is right for you

• This test measures the level of complement component C3, an important protein in your immune system
• It helps identify immune system activity and can detect conditions such as autoimmune disorders, infections, or inflammatory diseases
• Results guide your healthcare provider in monitoring disease activity and planning appropriate treatment

What is the Complement C3 test?

The Complement C3 test measures the amount of C3 protein in your blood. C3 plays a central role in the complement system, which helps your body fight infections and remove damaged cells. Abnormal levels of C3 can indicate immune system overactivity or deficiency, and can help in diagnosing autoimmune or inflammatory conditions.

This test is often recommended for:

• Individuals with suspected autoimmune conditions, such as lupus or vasculitis
• Patients experiencing unexplained inflammation or frequent infections
• People monitoring immune system function during treatment for autoimmune or inflammatory diseases
• Assessment of complement system activity in certain kidney or liver disorders

What are the symptoms of abnormal C3 levels?

Abnormal C3 levels may not cause noticeable symptoms directly, but they can be associated with underlying conditions, including:

• Fatigue, weakness, or malaise
• Recurrent infections
• Inflammatory symptoms such as joint pain, rashes, or swelling
• Kidney-related issues such as proteinuria or haematuria
• Flare-ups in autoimmune diseases

How does the Complement C3 test work?

A blood sample is taken and analysed to measure the concentration of C3 protein. Low levels may suggest consumption due to autoimmune activity or deficiency, while high levels can indicate inflammation or infection. The results provide valuable insight into immune system function and help guide further investigations or treatment plans.

What can I expect at my appointment?

Your appointment involves a standard blood draw performed by a trained healthcare professional. The procedure is quick and minimally invasive.

Results are typically available within 1-2 days. You will receive a report showing your C3 levels along with guidance from your healthcare provider regarding any follow-up or further testing if necessary.
