What's this test for?

This test is ideal if you're experiencing unexplained symptoms like joint pain, persistent sinus or lung issues, blood in your urine, chronic digestive problems, or unusual fatigue that hasn't gone away. These can sometimes point to autoimmune conditions where the body's immune system mistakenly attacks its own tissues, including blood vessels or the gut lining. This screen helps identify antibodies linked to these conditions so you can understand what might be causing your symptoms.

What's included in this test?

This screen looks for two main types of antibodies, P-ANCA and C-ANCA, along with specific markers called MPO and PR3 that help pinpoint what type of autoimmune activity might be happening. If the initial screen comes back positive, the test automatically runs a follow-up titer to measure how much antibody is present, giving a clearer picture of disease activity. Together, these markers help identify autoimmune conditions affecting blood vessels, the gut, or other organs.

What happens after I get my results?

Your results will show up in your account with each value's normal range clearly explained so you know exactly where you stand. If your results come back positive or unclear, next steps typically involve additional testing or monitoring symptoms closely, and if you have severe symptoms like difficulty breathing or major swelling, you should seek medical care right away. You can download the standard lab report directly from your account at any time, and if you retest in the future, the trends feature lets you track changes over time.

How can I naturally support immune system balance?

While autoimmune antibody levels aren't something you can directly control through lifestyle alone, supporting your immune system with a balanced diet rich in anti-inflammatory foods like leafy greens, fatty fish, and berries can help. Getting consistent sleep, managing stress through activities like walking or meditation, and avoiding smoking can also reduce overall inflammation in your body. These habits won't replace testing but can support your overall health while you monitor your results.

When will I get my results?

Results are typically ready within about 7 days after your sample is collected at the lab. If the initial screen is positive, the added titer test may take a bit longer since it runs as a reflex test to measure antibody levels more precisely. You'll get a notification as soon as your results are ready to view in your account.

Who should consider this test?

This test is a good fit for people with symptoms like unexplained joint or muscle pain, chronic sinus problems, blood in the urine, persistent digestive issues, or ongoing fatigue that hasn't been explained by other causes. It's also useful for anyone who has been told they might have an autoimmune condition affecting blood vessels or organs and wants clarity before pursuing further evaluation. People with a family history of autoimmune diseases may also want to consider this screening.

What symptoms indicate I may need this test?

Common symptoms linked to the conditions this test screens for include joint pain, skin rashes, numbness or tingling, blood in urine, chronic sinus or lung problems, and unexplained weight loss. Digestive symptoms like ongoing diarrhea, abdominal pain, or blood in stool can also be signs worth investigating. If you're dealing with several of these symptoms at once without a clear cause, this screening can help narrow down what's going on.

What does a positive ANCA result mean?

A positive result means antibodies were detected that are associated with autoimmune conditions affecting blood vessels or organs like the kidneys and lungs. This doesn't automatically mean you have a specific disease, but it's a signal that further evaluation is worthwhile, especially if paired with symptoms. The titer level that follows a positive screen shows how much antibody is present, which can help gauge how active the condition may be.

How often should I retest?

If your first result comes back negative and you're not experiencing symptoms, you likely don't need to retest unless new symptoms develop. If you've had a positive result or are being monitored for a known condition, retesting every few months can help track whether antibody levels are rising, falling, or staying stable. Your results being tracked over time can help you and anyone reviewing your case spot meaningful trends.

What should I do if my results are abnormal?

If your results are outside the normal range, start by reviewing the detailed explanation included with your report to understand what the specific antibodies mean. Keep track of any symptoms you're having and consider retesting in a few months to see if levels change. If you experience severe or worsening symptoms like difficulty breathing, significant swelling, or blood in urine, seek medical care right away rather than waiting for a scheduled retest.
