What's this test for?

This test is ideal if you're experiencing unexplained blood clots, repeated miscarriages, or symptoms that suggest an autoimmune condition like lupus. It checks for cardiolipin antibodies, which are proteins your immune system makes by mistake that can raise your risk of clotting problems. Many people take this test after a doctor visit history of unusual clotting events or pregnancy loss to understand what might be going on.

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 where you stand. If your antibody levels are elevated, next steps often include retesting in about 12 weeks to confirm the finding, since temporary elevations can happen after infections. You can download a standard lab report directly from your account at any time, and if you test again in the future, the trends feature lets you track changes over time.

What symptoms indicate I may need this test?

Common signs include unexplained blood clots in your legs or lungs, multiple miscarriages or pregnancy complications, unusual bruising, or low platelet counts. Some people also notice skin discoloration, headaches, or symptoms linked to autoimmune conditions like joint pain and fatigue. If you've had a stroke or clot at a younger age without a clear cause, this test can help explain why.

How can I naturally support healthy blood flow and immune balance?

Staying active with regular movement helps keep your blood circulating and lowers clotting risk. Eating an anti-inflammatory diet rich in fruits, vegetables, and omega-3 fats can support overall immune balance. Staying hydrated, avoiding smoking, and managing stress also help reduce strain on your circulatory and immune systems, though these habits work alongside, not instead of, appropriate medical care for confirmed antibody issues.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. Once ready, you'll get a notification and can log into your account to view the full report. The report breaks down your result and what it means in plain language.

Who should consider this test?

This test is a good fit for anyone with a history of unexplained blood clots, recurrent miscarriages, or a diagnosed autoimmune condition like lupus or rheumatoid arthritis. It's also useful if you've had a stroke or heart attack at a young age with no obvious cause. People with a family history of autoimmune clotting disorders may also want to check their levels.

What is Cardiolipin Antibody (IgM) and why does it matter?

Cardiolipin antibodies are proteins your immune system sometimes produces against a substance found in cell membranes called cardiolipin. When these antibodies are present in higher amounts, they're linked to a higher risk of blood clots, low platelet counts, and pregnancy complications. Measuring the IgM type specifically helps identify one piece of a broader autoimmune clotting risk picture.

What does high Cardiolipin Antibody (IgM) mean?

A high result suggests your immune system is producing antibodies that may increase your risk of blood clots or pregnancy-related complications. This doesn't automatically mean you have a clotting disorder, since levels can rise temporarily from infections or certain medications. A high result is usually followed by a repeat test in a few months to see if the elevation persists.

What causes high Cardiolipin Antibody (IgM) levels?

Elevated levels are most often linked to autoimmune conditions like lupus, rheumatoid arthritis, or Sjögren's syndrome. They can also show up temporarily after infections, certain medications, or in some cases without any clear underlying condition. Persistent high levels over multiple tests are what typically point toward an ongoing autoimmune process.

How often should I retest?

If your first result is elevated, retesting after about 12 weeks is a common approach to see if the antibody level is persistent or was just a temporary spike. If you have an ongoing autoimmune condition, periodic retesting every several months to a year can help you and track changes over time. Anyone with a personal history of clotting events may benefit from more frequent monitoring.
