ANTI PHOSPHOLIPID ANTIBODY IGG, SERUM

Anti-Phospholipid Antibody IgG, Serum

What it is

The Anti-Phospholipid Antibody IgG test measures IgG autoantibodies that target phospholipids, essential components of cell membranes. The presence of these antibodies is associated with Antiphospholipid Syndrome (APS), an autoimmune disorder that increases the risk of blood clots, recurrent miscarriages, and pregnancy complications.

Uses

This test helps in diagnosing Antiphospholipid Syndrome, especially in patients with unexplained clotting issues or recurrent pregnancy loss. It is also used to monitor patients with autoimmune conditions such as systemic lupus erythematosus (SLE), where APS may develop as a secondary complication.

Symptoms That May Lead to the Test

Doctors may recommend this test if a patient has a history of deep vein thrombosis (DVT), pulmonary embolism, stroke at a young age, multiple miscarriages, stillbirths, or autoimmune diseases with vascular involvement.

Abnormal Results

Positive Anti-Phospholipid Antibody IgG: Suggests a higher risk of Antiphospholipid Syndrome, blood clots, and pregnancy-related complications. Positive results are often confirmed with repeat testing and by evaluating IgM antibodies or lupus anticoagulant.

Negative Anti-Phospholipid Antibody IgG: Suggests a lower likelihood of APS, though repeat testing may be required if clinical suspicion is strong.

Risks

The Anti-Phospholipid Antibody IgG test is a routine blood test with minimal risks. Possible side effects include mild pain, bruising, or bleeding at the puncture site, and rarely dizziness or infection.
