The Complement Level C3 test is an important blood test used to evaluate the health of your immune system. Complement proteins play a crucial role in defending the body against infections, regulating inflammation, and enhancing immune responses. Among these proteins, Complement C3 is one of the most crucial and commonly measured components. Abnormal C3 levels can indicate autoimmune disorders, chronic inflammation, kidney disease, or recurrent infections.
In Pakistan, the Complement Level C3 test at Ibn-E-Sina Clinical Laboratory is widely trusted due to the lab’s reputation for accuracy, standardized procedures, and patient-friendly services. Ibn-E-Sina Clinical Laboratory operates multiple branches across major cities and is known for delivering reliable diagnostic results that doctors can confidently rely on.
This article provides complete and easy-to-understand details about the Complement Level C3 test price, preparation, procedure, report interpretation, and booking options in Pakistan. Whether your doctor has recommended this test for diagnosis, monitoring, or follow-up, this guide will help you understand every aspect before booking your test.
What is the Complement Level C3 Test?
The Complement Level C3 test measures the amount of Complement Component 3 (C3) in your blood. C3 is a protein produced by the liver and is a key part of the complement system, which works alongside antibodies to fight infections and remove damaged cells.
This test is also known as:
- Total Complement C3
- C3 Complement Test
- CH50 / CH100 (related complement activity tests)
Doctors commonly recommend the Complement Level C3 test to assess immune system function, especially when autoimmune or inflammatory diseases are suspected. It helps identify whether the immune system is overactive, underactive, or being consumed due to ongoing disease processes.
Why is the Complement Level C3 Test Important?
The Complement Level C3 test is important because it provides valuable insight into how well your immune system is functioning. Low or high C3 levels can signal serious underlying health conditions that require medical attention.
This test helps doctors:
- Detect autoimmune disorders like Systemic Lupus Erythematosus (SLE)
- Monitor disease activity and treatment response
- Identify immune deficiencies
- Assess kidney-related immune conditions such as glomerulonephritis
- Investigate recurrent or severe infections
Since complement proteins are consumed during inflammation, persistently low C3 levels often suggest active immune-related disease. This makes the test especially useful for long-term monitoring of chronic conditions.
When Should You Get a Complement Level C3 Test?
Your doctor may recommend a Complement Level C3 test at Ibn-E-Sina Clinical Laboratory if you experience or are being evaluated for:
- Suspected autoimmune diseases
- Unexplained fatigue, joint pain, or rashes
- Recurrent bacterial infections
- Kidney problems, such as swelling or protein in urine
- Monitoring known conditions like lupus or vasculitis
- Follow-up testing to assess treatment effectiveness
This test may also be ordered along with Complement C4, ANA tests, or other immune markers to provide a complete immune profile.
How to Prepare for the Complement Level C3 Test?
The Complement Level C3 test is simple and patient-friendly. In most cases, no special preparation is required.
General preparation guidelines include:
- Fasting: Not required unless combined with other tests
- Medications: Inform your doctor about ongoing medicines, especially immunosuppressants or steroids
- Hydration: Drink enough water before sample collection
- Rest: Avoid intense physical activity before the test
Always follow your doctor’s advice if specific instructions are provided.

The entire blood collection process takes only a few minutes and is performed with strict attention to hygiene, privacy, and patient comfort.
Complement Level C3 Report & Normal Values
The Complement Level C3 report shows whether your C3 levels fall within the normal reference range.
Normal Reference Values for Complement C3
| Test | Normal Range |
| Complement C3 | 90 – 180 mg/dL |
(Reference ranges may vary slightly depending on laboratory standards.)
Report Interpretation
- Normal C3 levels: Suggest balanced immune activity
- Low C3 levels: May indicate autoimmune disease, active inflammation, or immune consumption
- High C3 levels: Often linked to acute inflammation or infection
Only a qualified doctor can interpret your results accurately in combination with symptoms and other tests.
Understanding Abnormal Complement Level C3 Results
Low Complement C3 Levels May Be Seen In:
- Systemic Lupus Erythematosus (SLE)
- Rheumatoid arthritis
- Chronic kidney disease
- Severe infections
- Liver disease
High Complement C3 Levels May Be Seen In:
- Acute infections
- Inflammatory conditions
- Obesity-related inflammation
Abnormal results do not confirm a diagnosis on their own. Follow-up tests and clinical evaluation are essential for accurate diagnosis and treatment planning.
How to Support Immune Health Naturally (Optional)
