What's this test for?

This test is ideal if you've experienced unexplained blood clots, recurrent miscarriages, or have been diagnosed with an autoimmune disorder like lupus. It helps identify if your immune system is producing antibodies that increase your risk for dangerous clotting in veins and arteries, stroke, or pregnancy complications. Many people use this test when they have unexplained thrombosis, multiple pregnancy losses, or autoimmune symptoms that suggest antiphospholipid syndrome.

What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining what your cardiolipin antibody levels mean for your clotting risk, autoimmune health, and pregnancy safety if applicable. These notes include personalized recommendations such as lifestyle modifications, when to consider anticoagulation therapy, or whether you should consult a rheumatologist or hematologist. You'll also get the standard lab report and can track your antibody levels over time using our trends feature, which is especially helpful for monitoring autoimmune disease activity or treatment effectiveness.

What's included in this test?

This panel measures Cardiolipin Antibodies IgA, Cardiolipin Antibodies IgG, and Cardiolipin Antibodies IgM. Testing all three antibody classes provides a complete picture of your immune response and clotting risk, since each type can independently increase your risk for thrombosis, stroke, and pregnancy complications. Together, these measurements help diagnose antiphospholipid syndrome and guide treatment decisions for autoimmune-related clotting disorders.

How should I prepare for this test?

No special preparation is typically required for this test. You can take your regular medications and eat normally before your blood draw. However, if your doctor has ordered this test as part of diagnosing antiphospholipid syndrome, they may want to retest in 12 weeks to confirm positive results, as a single positive test isn't enough for diagnosis.

When will I get my results?

Most patients receive their cardiolipin antibody test results within 3-5 business days after the lab receives your sample. More complex cases or confirmation testing may take slightly longer. You'll be notified as soon as your results are available in your secure online portal.

Who should consider getting this test?

This test is important for anyone who has had unexplained blood clots, stroke at a young age, or recurrent pregnancy losses (especially in the second or third trimester). It's also recommended for people diagnosed with lupus or other autoimmune conditions, those with unexplained low platelet counts, or anyone with a family history of antiphospholipid syndrome. If you're planning pregnancy and have a history of complications, this test can provide crucial information.

What symptoms indicate I may need this test?

Consider this test if you've experienced blood clots in your legs or lungs without obvious cause, multiple miscarriages, or stroke at a relatively young age. Other signs include unexplained bruising or low platelet counts, livedo reticularis (a lacy purple discoloration of the skin), or symptoms of autoimmune disease like joint pain, fatigue, and rashes. If you have lupus or related conditions, this test helps assess your clotting risk.

What do positive cardiolipin antibodies mean?

Positive cardiolipin antibodies mean your immune system is producing antibodies that attack phospholipids in cell membranes, which can make your blood more likely to clot inappropriately. This increases your risk for deep vein thrombosis, pulmonary embolism, stroke, and pregnancy complications like miscarriage or preeclampsia. A single positive test needs to be confirmed with repeat testing 12 weeks later before making a diagnosis of antiphospholipid syndrome.

What causes elevated cardiolipin antibodies?

Elevated cardiolipin antibodies are most commonly associated with antiphospholipid syndrome, which can occur alone or alongside lupus and other autoimmune diseases. Temporary elevations can also occur with certain infections, medications, or other inflammatory conditions. The antibodies develop when the immune system mistakenly targets phospholipids, leading to increased clotting risk and inflammation in blood vessels.

How often should I retest my cardiolipin antibodies?

If your first test is positive, you'll need retesting in 12 weeks to confirm the diagnosis, as antiphospholipid syndrome requires persistent antibodies over time. Once diagnosed and on treatment, your doctor may monitor levels every 6-12 months to assess disease activity and treatment response. If you're negative but have ongoing symptoms or pregnancy complications, your doctor may recommend periodic retesting based on your individual situation.
