What's this test for?

This test is ideal if you're experiencing unexplained fatigue, joint pain, persistent inflammation, or mysterious symptoms that come and go. It helps identify autoimmune conditions where your immune system mistakenly attacks your own body tissues, such as lupus or other inflammatory disorders. Many people use this test when they have symptoms that don't have a clear cause and want to rule out or confirm autoimmune disease.

What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining what your immune system markers mean and whether they indicate autoimmune activity. These notes include personalized recommendations like dietary changes to reduce inflammation, lifestyle adjustments, or when to follow up with a rheumatologist. You'll also get the standard lab report and can track your immune markers over time using our trends feature to monitor disease activity or treatment effectiveness.

What's included in this test?

This panel measures Complement Component C3c, Anti-dsDNA (Double-Stranded) Antibodies, and ANA Screen IFA with Reflex to Titer and Pattern. This panel evaluates your immune system function and autoimmune activity through three key markers. Complement Component C3c measures part of your immune defense system that can be depleted during autoimmune flares. Anti-dsDNA antibodies are specific markers often elevated in lupus and other autoimmune conditions. The ANA screen identifies abnormal antibodies that attack your own tissues, helping pinpoint various autoimmune disorders. Together, these measurements provide crucial insights into whether your immune system is attacking your body.

How should I prepare for this test?

No special preparation is typically required for this autoimmune panel. You can take the test at any time of day and do not need to fast beforehand. Continue taking any prescribed medications unless your doctor specifically instructs otherwise, as stopping medications could affect your symptoms and health.

When will I get my results?

Most autoimmune blood test results are typically available within 1-3 business days after your sample reaches the laboratory. You'll receive an email notification as soon as your results are ready to view in your secure online account. Complex markers like ANA patterns may occasionally take slightly longer for detailed analysis.

Who should consider getting this test?

This test is important for anyone experiencing persistent fatigue, unexplained joint pain, recurring fevers, or skin rashes without a clear cause. It's especially valuable if you have a family history of autoimmune diseases like lupus, rheumatoid arthritis, or Sjogren's syndrome. People with symptoms that seem to come and go or worsen with stress should also consider this screening.

What symptoms indicate I may need this test?

Common symptoms include persistent fatigue that doesn't improve with rest, joint pain or swelling in multiple joints, unexplained fevers, skin rashes especially on sun-exposed areas, and sensitivity to sunlight. You may also experience hair loss, mouth sores, chest pain when breathing deeply, fingers turning white or blue in cold, or general malaise. If multiple symptoms appear together or fluctuate over time, autoimmune screening is warranted.

How can I naturally support my immune system with autoimmune issues?

Focus on an anti-inflammatory diet rich in omega-3 fatty acids from fish, colorful fruits and vegetables, and whole grains while limiting processed foods and sugar. Prioritize quality sleep, manage stress through meditation or gentle yoga, and avoid overexertion during flares. Getting adequate vitamin D through sunlight or supplements may help regulate immune function, and staying well-hydrated supports overall health.

What does a positive ANA test mean?

A positive ANA (antinuclear antibody) test means your immune system is producing antibodies that target components of your own cell nuclei, which is common in autoimmune diseases. However, a positive ANA alone doesn't diagnose a specific condition, as it can appear in healthy people or with infections. The pattern and titer level, along with other markers and symptoms, help your doctor determine if you have an autoimmune disorder like lupus or mixed connective tissue disease.

What causes low complement C3 levels?

Low C3 complement levels typically occur when your immune system is actively fighting inflammation or infection, depleting this important protein. In autoimmune diseases like lupus, immune complexes consume C3 as they form and deposit in tissues. Low C3 can also result from genetic complement deficiencies, chronic infections, or kidney disease that causes protein loss.

How often should I retest for autoimmune markers?

If you're newly diagnosed with an autoimmune condition or adjusting treatment, your doctor may recommend retesting every 2-3 months to monitor disease activity. Once your condition is stable, testing every 6-12 months helps track long-term management. If you experience a flare-up of symptoms or significant changes in how you feel, retest sooner to assess disease activity and adjust treatment accordingly.
