Phosphatidylinositol IgG Antibody Blood Test | Antiphospholipid Screen
Uncover hidden antibody drivers of clotting and pregnancy loss.
The Phosphatidylinositol IgG Antibody Blood Test is a specialised component of the antiphospholipid screen, used to detect IgG antibodies directed against phosphatidylinositol, a phospholipid found in cell membranes. This test is typically requested when there is clinical suspicion of antiphospholipid syndrome (APS), a condition associated with an increased risk of venous or arterial thrombosis, recurrent pregnancy loss, and certain pregnancy complications. It may be particularly useful in patients with unexplained clotting events, recurrent miscarriage, or autoimmune conditions such as lupus, where standard antiphospholipid antibodies (lupus anticoagulant, anticardiolipin, and anti-beta-2-glycoprotein I) are negative but clinical suspicion remains high.
Marker included
- Phosphatidylinositol IgG antibody: detects and quantifies IgG class antibodies against phosphatidylinositol, helping to identify a prothrombotic autoimmune profile.
Why it matters
Identifying phosphatidylinositol IgG antibodies can provide valuable diagnostic information in patients with unexplained thrombosis or pregnancy morbidity, guiding further clinical assessment and management. Early detection supports informed decisions about anticoagulation and pregnancy care, and helps clarify the risk of recurrent events in individuals with autoimmune backgrounds.

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.
