What's this test for?
This test is ideal if you're experiencing unexplained symptoms that suggest immune system or inflammatory issues, such as persistent swelling, joint pain, or kidney-related problems. It helps identify conditions like lupus, certain types of kidney inflammation, or other autoimmune processes that may be affecting your overall health. Many people use this test when doctors suspect an immune-related disorder but need concrete lab evidence to guide diagnosis and treatment.
How should I prepare for this test?
No special preparation is typically required for this test. You can take your regular medications and eat normally before your blood draw. However, if you're having other tests done at the same time, your healthcare provider may give you specific instructions. Always inform the lab staff about any medications or supplements you're taking, as some may affect test interpretation.
What's included in this test?
This test measures Complement Component C3c, a crucial protein in your immune system that helps fight infections and clear damaged cells. C3c levels provide important insights into autoimmune conditions like lupus, kidney inflammation disorders, and other immune complex diseases that can cause unexplained symptoms. Abnormal levels help doctors understand whether your immune system is overactive, underactive, or being consumed by ongoing inflammation, guiding appropriate treatment decisions.
What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your Complement C3c levels mean for your immune system function and overall health. These notes include personalized recommendations like lifestyle modifications, when to follow up with a rheumatologist or nephrologist, or whether additional immune testing is needed. You'll also get the standard lab report and can track your C3c levels over time using our trends feature, which is especially helpful for monitoring autoimmune conditions or treatment effectiveness.
When will I get my results?
Most Complement C3c test results are available within 1-3 business days after your blood sample reaches the laboratory. You'll receive an email notification when your results are ready to view in your secure online account. If your doctor has ordered this as part of a larger panel, all results will be available together once the longest test is completed.
Who should consider getting this test?
This test is important for people experiencing symptoms that suggest autoimmune or inflammatory conditions, such as unexplained swelling, persistent joint pain, kidney problems, or recurrent infections. It's also valuable for those with a family history of lupus or other autoimmune diseases, anyone being monitored for known autoimmune conditions, or people whose doctors suspect immune complex disorders based on other symptoms or test results.
What symptoms indicate I may need this test?
Common symptoms that may indicate the need for this test include unexplained swelling or fluid retention, persistent joint pain or inflammation, unusual fatigue, recurring infections, protein or blood in your urine, or kidney problems. Other signs include skin rashes that don't respond to treatment, unexplained fevers, or symptoms consistent with lupus or other autoimmune conditions. If you have multiple vague symptoms that doctors haven't been able to explain, this test may provide important clues.
How can I naturally support my immune system health?
Supporting healthy immune function starts with getting adequate sleep, managing stress through relaxation techniques, and eating a balanced diet rich in fruits, vegetables, and omega-3 fatty acids. Regular moderate exercise can help regulate immune responses, while avoiding smoking and excessive alcohol supports overall immune health. For autoimmune conditions specifically, identifying and managing triggers, maintaining a healthy weight, and working closely with your healthcare provider on appropriate treatment plans is essential.
What does low Complement C3c mean?
Low C3c levels often indicate that your immune system is actively fighting something and consuming complement proteins faster than they're being produced. This is commonly seen in conditions like lupus, certain types of kidney inflammation, immune complex diseases, or during active autoimmune flares. Low levels help doctors confirm autoimmune diagnoses and monitor disease activity, though additional testing is usually needed to determine the specific cause and appropriate treatment.
How often should I retest my Complement C3c levels?
If you've been diagnosed with an autoimmune condition like lupus, your doctor may retest every 3-6 months or during symptom flares to monitor disease activity. For initial diagnosis purposes with normal results but ongoing symptoms, retesting in 2-3 months may be recommended. If you're on treatment for an autoimmune condition, more frequent testing every 6-12 weeks helps assess treatment effectiveness and adjust medications as needed.

What this means
Your Complement C3c level is below the optimal range, which may indicate that your immune system is actively consuming complement proteins. This can occur during autoimmune flares, active lupus, or kidney inflammation, and suggests your immune system may be working harder than normal to address an underlying condition.
Recommended actions

Keep a symptom diary tracking joint pain, swelling, fatigue, or other changes
Focus on anti-inflammatory foods like fatty fish, leafy greens, and berries
