What's this test for?

This test is ideal if you're experiencing recurrent blood clots or have had multiple unexplained miscarriages, since these can be signs of an autoimmune condition called antiphospholipid syndrome (APS). It's also useful if a prior blood test already showed beta-2-glycoprotein I antibodies and more detail is needed about which part of the protein your immune system is targeting. Pinpointing this helps clarify your risk level for future clotting events.

What's included in this test?

This test measures one specific type of antibody that targets a particular region (called Domain 1) of a protein called beta-2-glycoprotein I. This particular antibody matters because, unlike antibodies to other parts of the same protein, it's specifically linked to a higher risk of dangerous blood clots forming in your veins.

What happens after I get my results?

Your results will show up in your account along with an explanation of what a normal versus a positive result looks like. If your result is positive, a common next step is retesting at least 12 weeks later to confirm the finding, since a single positive result isn't enough to make a lasting diagnosis. You can download a standard lab report from your account at any time, and if you test again in the future, you'll be able to track how your results change over time using the trends feature.

How can I naturally support healthy circulation?

While you can't change antibody levels through lifestyle alone, you can lower your overall clotting risk by staying active, avoiding long periods of sitting or immobility, and staying well hydrated. Not smoking and maintaining a healthy weight also reduce clot risk. If you're on long flights or car rides, moving your legs periodically and wearing compression socks can help.

When will I get my results?

Results for this test are typically ready within about 7 days of your sample being collected at the lab. You'll get a notification once they're available to view in your account.

Who should consider this test?

This test is a good fit for people who've had a blood clot in a vein (like a deep vein thrombosis or pulmonary embolism) without a clear cause, or who've experienced repeated pregnancy losses. It's also relevant if you've already tested positive for general beta-2-glycoprotein I antibodies and want more specific information about your clotting risk.

What symptoms indicate I may need this test?

Symptoms like leg swelling, pain, or warmth from a possible blood clot, sudden shortness of breath, or a history of multiple miscarriages (especially after 10 weeks of pregnancy) are reasons to consider this test. Recurrent early pregnancy loss can also be a signal worth investigating.

What does a positive result mean?

A positive result means your immune system is producing antibodies against Domain 1 of beta-2-glycoprotein I, which research links to a higher chance of developing blood clots in your veins. It doesn't mean a clot will definitely happen, but it's an important piece of information for understanding your overall clotting risk, especially when combined with your symptom history.

How often should I retest?

If your first result is positive, it's recommended to retest at least 12 weeks later to confirm the antibody is persistently present rather than a temporary finding. Repeated confirmation over time gives a much clearer picture than a single test.

What should I do if my results are abnormal?

If your result comes back positive, watch closely for symptoms like leg swelling, chest pain, or shortness of breath, and seek emergency medical care right away if these occur since they can signal a serious clot. Otherwise, plan to retest in 12 weeks as recommended, and in the meantime focus on lowering other clot risk factors like smoking, inactivity, and dehydration.
