What's this test for?

This test is ideal if you're experiencing unexplained blood clots, recurrent miscarriages, or pregnancy complications that haven't been explained by other causes. It looks for antibodies that can make your blood clot more easily than it should. Many people with these antibodies have no obvious symptoms until a clotting event or pregnancy loss occurs, which is why testing can help identify a hidden risk factor.

What's included in this test?

This test measures a single, specific antibody category rather than a broad panel, so it's a focused check rather than a general screen. It's often ordered alongside other clotting antibody tests because looking at multiple markers together gives a fuller picture of clotting risk than any one result alone.

What happens after I get my results?

Your results will show up in your account with a clear explanation of what's considered a normal versus elevated antibody level. If your level comes back high, next steps often include repeat testing after 12 weeks to confirm the result, since antibody levels can fluctuate, along with paying closer attention to symptoms like leg swelling, chest pain, or unusual bleeding that would warrant urgent care. You can download the full lab report from your account at any time, and use the trends feature to track this and other markers over future testing.

How can I naturally support healthy blood clotting balance?
Staying well hydrated, moving regularly, and avoiding long periods of sitting can all help support healthy circulation. Not smoking and maintaining a healthy weight are also linked to lower clotting risk. These habits don't replace testing or medical care for a diagnosed clotting disorder, but they're supportive everyday steps.
When will I get my results?
Results are typically ready within about 7 days of your sample being collected at the lab. You'll get a notification as soon as your report is available in your account, so there's no need to call and check.
Who should consider this test?
This test is a good fit for anyone who has had an unexplained blood clot, especially at a younger age, or someone with a history of repeated pregnancy losses or late pregnancy complications. It's also relevant if you've already tested positive for other clotting-related antibodies and want a fuller picture. People with a family history of clotting disorders may also want to consider it.
What symptoms indicate I may need this test?
Signs to watch for include swelling, pain, or warmth in one leg, sudden shortness of breath or chest pain, or a stroke or mini-stroke at a young age. Recurrent early miscarriages, a stillbirth, or severe pregnancy complications like preeclampsia are also reasons this test may be relevant. If you're having any severe or sudden symptoms like chest pain or difficulty breathing, seek emergency medical care right away rather than waiting for test results.
What does a high antibody result mean?
A high result means these antibodies were found in your blood at a level associated with increased clotting risk, which is linked to conditions like antiphospholipid syndrome. It doesn't mean a clot will definitely happen, but it flags a higher chance and usually calls for confirmation with a repeat test after about 12 weeks. Lifestyle steps like staying active, not smoking, and staying hydrated become especially important with a high result.
What causes high PS/PT antibody levels?
These antibodies are produced by the immune system mistakenly targeting your own proteins involved in blood clotting, a process seen in autoimmune conditions like lupus and antiphospholipid syndrome. Sometimes they show up temporarily after infections or with certain medications, which is part of why a confirming retest matters. In other cases, no clear trigger is ever identified.
How often should I retest?
If your first result is positive or high, retesting after about 12 weeks is the standard approach to confirm whether the antibody is persistent or was a temporary finding. If your result is normal and you have no new symptoms, there's usually no need to retest unless your health situation changes. Anyone with an ongoing clotting condition being monitored may retest more regularly as advised by their care plan.

What this means

A negative result means no significant levels of this clotting-related antibody were detected in your blood. This lowers the likelihood that PS/PT antibodies are contributing to unexplained clotting or pregnancy loss. A negative result doesn't rule out other causes of clotting risk, especially if symptoms continue.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
