About this test

The ACA IgA test detects IgA antibodies against cardiolipin, a phospholipid in cell membranes. These antibodies can increase the risk of abnormal blood clotting.

A normal result is negative, typically below 12–20 APL U/mL, varying by lab.

Positive ACA IgA may be associated with antiphospholipid syndrome (APS), causing blood clots (DVT, stroke), recurrent miscarriages, and pregnancy complications, especially in people with lupus (SLE).

IgA is not part of standard APS criteria but is useful when IgG and IgM tests are negative despite strong suspicion. Persistent positivity over 12 weeks is significant.

Questions about this test

When should I get the ACA IgA test?

You should get an ACA IgA test if you have unexplained blood clots, stroke at a young age, or recurrent miscarriages, especially when anticardiolipin IgG and IgM tests are negative but antiphospholipid syndrome is still suspected. It is also recommended for people with lupus (SLE) or other autoimmune diseases, and low platelets.

How should I prepare for the ACA IgA test?

No special preparation or fasting is required for an ACA IgA test. Inform your doctor about any blood thinners (don’t stop them without advice), recent infections, blood clots, or pregnancy, as infections can cause temporary positive results. A repeat test after 12 weeks may be needed to confirm a positive result.

Do I require fasting for the ACA IgA test?

No, fasting is not required for an ACA IgA test. You can eat and drink normally before giving your sample, and the test can be done at any time of day. Inform your doctor about any blood thinners, recent infections, or pregnancy, and don’t stop prescribed medicines without advice.
