Cardiolipin - IgA Antibody, Serum

Cardiolipin - IgA Antibody, Serum

Cardiolipin - IgA Antibody, Serum Test is a specialized blood test used to detect IgA antibodies against cardiolipin, a type of phospholipid found in cell membranes. This test helps in the diagnosis and monitoring of Autoimmune Disorders, especially Antiphospholipid Syndrome (APS) and certain clotting-related conditions.

Why This Test is Done

Doctors may recommend this test if a patient has:

• Recurrent blood clots (thrombosis)
• Unexplained miscarriages or pregnancy complications
• Autoimmune disorders like lupus
• Stroke at a young age
• Suspected antiphospholipid antibody syndrome

What the Test Detects

The test measures:

• Cardiolipin IgA Antibodies present in serum

Elevated levels may indicate:

• Antiphospholipid Syndrome (APS)
• Autoimmune connective tissue disorders
• Increased tendency for abnormal blood clotting

Specimen Required

• Sample Type: Serum
• Method: Immunoassay / ELISA

Preparation

• Usually no fasting is required
• Inform your doctor about ongoing medications or anticoagulant therapy

Benefits of the Test

• Helps identify autoimmune clotting disorders
• Assists in recurrent miscarriage evaluation
• Supports early diagnosis of APS
• Useful for monitoring autoimmune disease activity

Interpretation

• Negative Result: No significant IgA cardiolipin antibodies detected
• Positive Result: May suggest autoimmune-mediated clotting tendency and requires clinical correlation

Recommended For

• Individuals with unexplained clotting disorders
• Patients with recurrent pregnancy loss
• People with autoimmune disease symptoms
• Lupus or APS evaluation

Reporting Time

• Typically: 3–7 Working Days (may vary by laboratory)

Note

Test results should always be interpreted along with clinical findings and other antiphospholipid antibody tests such as:

• Lupus Anticoagulant
• Beta-2 Glycoprotein Antibodies
• Cardiolipin IgG & IgM Antibodies
