APA (Anti Phospholipid Antibody) IgG Antibody, Serum
Overview
The APA (Anti Phospholipid Antibody) IgG Antibody, Serum test is used to detect IgG class antiphospholipid antibodies present in the blood. These antibodies may mistakenly attack healthy phospholipids and proteins associated with cell membranes, increasing the risk of abnormal blood clot formation and certain autoimmune conditions.
This test is commonly recommended in the evaluation of:
- Recurrent miscarriages
- Unexplained blood clots
- Autoimmune disorders
- Suspected Antiphospholipid Syndrome (APS)
- Lupus-related complications
Why This Test is Done
Doctors may advise this test if a patient experiences:
- Repeated pregnancy loss
- Deep vein thrombosis (DVT)
- Stroke at a young age
- Autoimmune disease symptoms
- Prolonged clotting abnormalities
- Unexplained vascular complications
What Does the Test Measure?
This test measures the level of:
- Anti Phospholipid Antibody (APA) – IgG
Elevated IgG antibody levels may indicate:
- Antiphospholipid Syndrome (APS)
- Systemic Lupus Erythematosus (SLE)
- Increased tendency for blood clot formation
- Autoimmune activity
Sample Type
Preparation Required
- No fasting is usually required
- Inform your doctor about ongoing medications, anticoagulants, or autoimmune treatments
Who Should Consider This Test?
- Individuals with recurrent miscarriages
- Patients with unexplained clotting disorders
- People with autoimmune disease symptoms
- Patients with lupus or suspected APS
- Individuals with unexplained prolonged clotting times
Benefits of the Test
✔ Helps diagnose Antiphospholipid Syndrome
✔ Assists in evaluating clotting risk
✔ Supports autoimmune disease diagnosis
✔ Useful in recurrent pregnancy loss evaluation
✔ Helps guide treatment and monitoring
Interpretation of Results
-
Negative/Normal: Antibody levels are within normal range
-
Positive/Elevated: May suggest autoimmune activity or increased clotting risk
Results should always be interpreted along with:
- Clinical symptoms
- Medical history
- Other autoimmune and coagulation tests
Additional Information
- This test may be performed along with:
- Cardiolipin Antibodies
- Lupus Anticoagulant
- Beta-2 Glycoprotein Antibodies
- Repeat testing after 12 weeks may be recommended for confirmation
What You Receive

No, fasting is generally not required.
Why is this test important in pregnancy?
It helps evaluate recurrent miscarriages and clotting-related pregnancy complications.
Can this test diagnose APS?
It supports APS diagnosis when combined with symptoms and other laboratory findings.
What happens if the result is positive?
Your doctor may recommend additional tests, repeat testing, or treatment based on your condition.
