Phosphatidylserine IgM Test | Antiphospholipid Screen
Uncover a hidden antibody linked to abnormal clotting.
The Phosphatidylserine IgM Test is a focused blood test that detects IgM-class antibodies directed against phosphatidylserine, a phospholipid normally found on the inner surface of cell membranes. These antibodies belong to the broader family of antiphospholipid antibodies and are associated with an increased tendency to form blood clots (thrombosis) or to experience pregnancy complications. This test is typically requested for patients with unexplained arterial or venous thrombosis, recurrent miscarriage, or other features suggestive of antiphospholipid syndrome (APS). It may also be used as part of a thrombophilia screen or in the investigation of autoimmune conditions such as systemic lupus erythematosus (SLE).
Marker included
- Phosphatidylserine IgM antibody (Anti-PS IgM): Detects and measures IgM antibodies that bind to phosphatidylserine. The presence of these antibodies can indicate an antiphospholipid antibody profile and may support the diagnosis of antiphospholipid syndrome when considered alongside clinical findings and other antiphospholipid tests.
Why it matters
Identifying phosphatidylserine IgM antibodies can help clinicians assess the risk of thrombosis and pregnancy loss, guide further investigation, and inform management decisions for patients with suspected antiphospholipid syndrome. Early detection supports timely and appropriate care.

No special preparation required.
For blood tests, we recommend drinking plenty of water beforehand to ensure smooth sample collection. If you are taking any regular medication, continue to do so unless advised otherwise by your doctor.
Important Clinical Information:
This test is a screening tool to monitor and support your overall health. It does not replace your GP or consultant.
Always discuss your test results, especially any abnormal results, with your GP, who can interpret them in the context of your medical history and overall health.
