Phospholipid IgG Antibody Test | Antiphospholipid Screen

The Phospholipid IgG Antibody Test is a focused blood test that detects IgG-class antibodies directed against phospholipids, the fatty molecules that form the outer layer of cells and play a key role in normal blood clotting. It is used as part of the antiphospholipid screen to help investigate an increased tendency to thrombosis (blood clots) or recurrent pregnancy loss, and to support the assessment of antiphospholipid syndrome (APS). It may be requested for people with unexplained venous or arterial thrombosis, recurrent miscarriage, or certain autoimmune conditions such as lupus, and it can be used alongside other antiphospholipid markers to build a fuller picture.

What it screens for

• Phospholipid IgG antibodies (Anti-Phospholipid IgG): Detects and, where relevant, quantifies IgG antibodies that bind to phospholipids. The presence of these antibodies can be associated with an increased risk of abnormal blood clotting and with pregnancy complications. Results are interpreted alongside the patient's clinical history and other antiphospholipid tests.

Why it matters

Phospholipid IgG antibodies are one of the key markers in the antiphospholipid screen. Identifying them can help explain otherwise unexplained clotting events or recurrent pregnancy loss, guide further investigation, and inform discussions about monitoring and risk management with the patient's doctor. Because these antibodies can also be found in people without symptoms, results are always considered together with the clinical picture and, where appropriate, repeat testing.

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.
