About this service

Complement C3 analysis (Complement C3, Serum) is a medical test used to evaluate the levels of C3 protein in the blood, which is an essential component of the immune complement system. C3 protein plays a vital role in enhancing the immune response by helping activate immune cells and eliminate pathogens and foreign substances. This test is used to diagnose and monitor a range of health conditions, such as inflammatory diseases, autoimmune disorders, and infections. Elevated or decreased C3 levels may indicate certain immune system disorders, assisting physicians in determining an appropriate treatment plan. It is important to perform this test as part of a comprehensive assessment of the patient’s condition, alongside other tests when needed.

Purpose Test

Immune system function: showing how the body responds to infections or inflammation.
Inflammatory diseases: such as systemic lupus erythematosus and rheumatoid arthritis.
Autoimmune diseases: low levels may indicate disease activity.
Infections: elevated levels can occur during the body’s response to infection.

Recommended groups

Individuals with inflammation symptoms: such as fever, pain, or unexplained fatigue.
Patients with autoimmune diseases: such as systemic lupus erythematosus or rheumatoid arthritis, to monitor disease activity.
Individuals with recurrent or severe infections: to assess the immune system’s response capability.
Patients with severe allergic conditions: to understand immune response.
Individuals diagnosed with kidney diseases: to evaluate their impact on the immune system.

Symptoms indicative

Unexplained fever: elevated temperature without a clear cause.
Joint or muscle pain: persistent pain or swelling in the joints.
Severe fatigue: continuous tiredness and inability to perform daily activities.
Skin rash: unexplained rash, especially if associated with other symptoms.
Recurrent infections: infections occurring unusually often or severe infections.
Immune-related symptoms: such as weight loss, loss of appetite, and mood changes.

Normal Levels

75 to 135 mg/dL.
