ANTI CARDIOLIPIN ANTIBODY IGG

Anti-cardiolipin IgG is a blood test that detects IgG antibodies against cardiolipin (a phospholipid). It’s mainly used to evaluate for Antiphospholipid syndrome (APS).

🔬 What It Means

• IgG = longer-lasting antibody.

• Persistent moderate/high IgG levels are more strongly associated with clotting risk than IgM.

• Can also be seen with autoimmune diseases like Systemic lupus erythematosus.

🧪 Why Doctors Order It

• Unexplained blood clots (DVT, stroke in young patients)

• Recurrent pregnancy complications (in older patients)

• Suspected antiphospholipid syndrome

• Part of an autoimmune evaluation

📊 Interpretation (General Guide)

For APS diagnosis, the antibody should be positive on two tests at least 12 weeks apart and associated with clinical findings (like clots).

📝 Key Points

• IgG is generally more clinically significant than IgM.

• One positive test alone does not confirm APS.

• Results must be interpreted with symptoms and other labs (e.g., lupus anticoagulant, anti-β2 glycoprotein I).
