What's this test for?

This test is ideal if you're experiencing unexplained blood clots, repeated miscarriages, or have been told you might have an autoimmune condition like lupus. It checks for antibodies that attack a substance in your cells, which can raise your risk for clotting problems, low platelet counts, and pregnancy loss. It's also useful if you already have an autoimmune diagnosis and your provider wants to understand your clotting risk better.

What's included in this test?

This test measures two types of cardiolipin antibodies. Each type reflects a different pattern of immune activity, and looking at both together gives a fuller picture of your clotting and autoimmune risk than checking just one alone.

What happens after I get my results?

Your results will be available in your account, with each value explained alongside its normal range so you know exactly where you stand. If your levels come back elevated, next steps often include retesting to confirm the result, since antibody levels can fluctuate, and discussing symptoms like unusual bruising, swelling, or pregnancy complications with a specialist. The standard lab report can be downloaded directly from your account for your records. You can also track your results over time using the trends feature to see how your levels change.

When will I get my results?

Results are typically ready within about 7 days of your sample being collected. Once processed, they'll be uploaded to your secure online account where you can view and download them anytime.

Who should consider this test?

People with a history of unexplained blood clots, multiple miscarriages, or unusually low platelet counts should consider this test. It's also worth considering if you've been diagnosed with lupus, rheumatoid arthritis, psoriatic arthritis, or Sjögren's syndrome, since these conditions carry a higher chance of having these antibodies present.

What symptoms indicate I may need this test?

Watch for symptoms like swelling or pain in a leg (which can signal a clot), sudden vision changes, repeated pregnancy losses, easy bruising, or unexplained fatigue and joint pain. If you've had a stroke or heart attack at a younger age without a clear cause, this test may also be worth considering. These signs don't confirm a problem on their own, but they're reasons to get checked.

What does high cardiolipin antibody level mean?

A high result means your immune system is producing antibodies that can make your blood more likely to clot abnormally. This doesn't guarantee you'll develop a clot, but it does mean your risk is elevated, especially if you also have symptoms or another autoimmune condition. Simple steps like staying active, staying hydrated, avoiding long periods of immobility, and not smoking can help lower overall clotting risk while you look into next steps.

What causes high cardiolipin antibody levels?

Elevated levels are most often linked to autoimmune conditions like lupus, antiphospholipid syndrome, rheumatoid arthritis, or Sjögren's syndrome. Sometimes infections or certain medications can also temporarily raise antibody levels. Because levels can fluctuate, a single high result is usually confirmed with a repeat test weeks later.

How often should I retest?

If your first result is elevated, retesting after about 12 weeks is common practice to confirm whether the antibodies are persistent, since temporary spikes can happen. If you have an ongoing autoimmune condition, periodic retesting can help track changes in your risk over time. Your trends dashboard makes it easy to compare results side by side.

What should I do if my results are abnormal?

If your results come back outside the normal range, don't panic — start by reviewing the explanation provided with your report to understand what it means for you specifically. Consider scheduling a confirmatory retest in a few months, and pay attention to any new symptoms like leg swelling, chest pain, or vision changes, which need urgent attention. Sharing your full result history with a specialist who manages autoimmune or clotting conditions can help guide any additional steps.
