What's this test for?

This test is ideal if you're experiencing unexplained joint pain, fatigue, skin rashes, or muscle aches that won't go away. These kinds of symptoms can sometimes point to your immune system mistakenly attacking your own body, which is called an autoimmune reaction. This screen helps check whether that's happening so you can get clearer answers about what's behind your symptoms.

How should I prepare for this test?

How can I naturally support my immune system? Getting enough sleep, eating a balanced diet rich in fruits and vegetables, managing stress, and staying active can all help keep your immune system functioning well. Reducing processed foods and added sugar may also help lower inflammation in the body. These habits won't replace testing, but they support your overall immune health alongside monitoring your results.

What's included in this test?

This screen checks for antinuclear antibodies, which are markers your immune system produces when it starts targeting your own tissues by mistake. If the initial screen is positive, the lab automatically runs a titer, which measures how much antibody is present and gives a better sense of how active the reaction is. Together these results help identify signs of autoimmune activity without needing a separate follow-up order.

What happens after I get my results?

Your results will show up in your account with each value explained alongside its normal range, so you know exactly what's typical and what isn't. If your screen comes back positive, the report includes a reflex titer that shows how strong the reaction is, which helps put the result into context. Depending on what you see, next steps might include lifestyle changes like better sleep and stress management, or retesting down the road to track changes. You can download the full lab report anytime and use the trends feature to watch your results over time.

When will I get my results?

Results are typically ready within about 7 days of your sample being collected. If your initial screen is positive, the automatic reflex titer may add a small amount of time since it's run as a follow-up step at the lab. You'll get a notification as soon as your results are posted to your account.

Who should consider this test?

This test is a good fit for anyone dealing with ongoing, unexplained symptoms like joint pain, fatigue, rashes, or muscle weakness that haven't been traced to another cause. It's also useful if autoimmune conditions run in your family and you want to check your own status. People who've had unusual lab findings in the past, like inflammation markers, may also want this screen for more clarity.

What symptoms indicate I may need this test?

Common signs include joint pain or swelling, persistent fatigue that doesn't improve with rest, unexplained skin rashes, hair loss, muscle aches, or low-grade fevers that come and go. Some people also notice sensitivity to sunlight or dry eyes and mouth. If you've had several of these symptoms for weeks or months without a clear reason, this screen can help you understand what's going on.

What does a positive result mean?

A positive antinuclear antibody result means your immune system is producing antibodies that target your own cells, which can happen with various autoimmune conditions. The titer number that follows shows how strong this reaction is — higher titers generally suggest a more active immune response. It's worth noting that some healthy people can have a mildly positive result without having any disease, so the number is just one piece of the picture.

What causes a positive autoantibody result?

Autoimmune conditions are the most common reason, but infections, certain medications, and even normal aging can sometimes cause a positive result. Family history plays a role too, since autoimmune tendencies can run in families. Chronic stress and inflammation may also contribute to immune system changes that show up on this screen.

How often should I retest?

If your first result is negative and you're not having symptoms, you likely don't need to retest unless new symptoms appear. If your result is positive or borderline, retesting every 6 to 12 months can help you track whether the titer is rising, falling, or staying stable over time. Tracking your results through the trends feature makes it easy to spot patterns between tests.
