Anticardiolipin Antibodies (IgG) in Jamshedpur

Know More About This Test

The Anti-Cardiolipin Antibody IgG test detects IgG antibodies against cardiolipin, which are associated with antiphospholipid syndrome (APS). This condition causes abnormal blood clotting and is important in recurrent pregnancy loss. It serves as an autoimmune diagnostic marker.

Why Is This Test Recommended?

This test is recommended for:

• Recurrent miscarriages
• Unexplained thrombosis
• Autoimmune disease evaluation
• Stroke in young individuals
• Lupus assessment

Understanding Anti-Cardiolipin IgG

Persistent positivity indicates APS. Transient rise may occur during infection. High titers increase clot risk. Results must be confirmed after 12 weeks and are often combined with lupus anticoagulant testing.

Symptoms or Conditions That May Require This Test

• Recurrent pregnancy loss
• Deep vein thrombosis
• Stroke at young age
• Autoimmune symptoms
• Unexplained clotting episodes

How Do I Prepare for the Test?

No fasting required. Blood is drawn from a vein. Inform your doctor about autoimmune history. Repeat testing is required for confirmation.

How Is the Test Performed?

A blood sample is collected from a vein in your arm. The procedure is safe and quick.

What Happens After the Test?

A positive test requires confirmation with repeat testing after 12 weeks. Results guide long-term anticoagulation therapy. Pregnancy monitoring is essential for affected women. Combined marker interpretation is needed, and specialist consultation is advised. What Do the Results Mean?

Results are typically reported in GPL units (where 1 GPL unit equals the binding activity of 1 microgram of IgG antibody).

• Negative (< 15 GPL): This is considered a normal result, indicating that significant levels of IgG antibodies were not detected at the time of the test.
• Weakly Positive (15 – 40 GPL): Low levels may be present due to age, recent infections, or certain medications and may not be clinically significant.
• Positive (> 40 GPL): Moderate to high levels suggest a strong association with Antiphospholipid Syndrome or an underlying autoimmune condition.

Important Clinical Rule: A diagnosis of APS is never made based on a single positive result. Because these antibodies can appear temporarily, international guidelines require a repeat test 12 weeks later. If the second test is also positive, the antibodies are considered "persistent," and a diagnosis can be confirmed.

Frequently Asked Questions (FAQs)

1. Is one positive test enough? No, a single positive result must be confirmed with repeat testing after at least 12 weeks to diagnose antiphospholipid syndrome.
2. Can infection cause positivity? Yes, transient elevations can occur during infections or acute illness, which is why confirmation testing is essential.
3. Is it treatable? Manageable; while not curable, APS is manageable with anticoagulant therapy and close monitoring to prevent complications.
4. Is it hereditary? Not directly; APS is an acquired autoimmune condition, though there may be genetic predisposition to autoimmune disorders in families.
5. Is repeat testing needed? Yes, repeat testing after 12 weeks is mandatory for diagnosis, and periodic monitoring may be needed during treatment.
