Serum or Plasma Immunoassay for Anti-Cardiolipin Antibodies (IgG)
This test measures the presence of antibodies in your blood that target cardiolipin, a fatty substance found in cell membranes. These antibodies may be linked to certain autoimmune conditions.

What This Test Measures
Anti-cardiolipin antibodies are proteins your immune system produces in response to cardiolipin, a phospholipid commonly found in cell membranes. This test detects IgG antibodies against cardiolipin, which may indicate an autoimmune response.
Why It’s Ordered
Doctors may order this test if you have symptoms suggestive of autoimmune diseases (e.g., lupus, antiphospholipid syndrome) or if you’ve had unexplained blood clots, recurrent miscarriages, or other unexplained health issues.
Common Uses
Results are often used alongside other tests (like lupus anticoagulant or ANA) to diagnose or monitor autoimmune conditions. It’s not a standalone diagnostic tool but supports broader evaluations.
What to Expect Before the Test
No special preparation is needed. A blood sample is drawn from a vein, usually in your arm. You may feel slight discomfort, but it lasts only a few minutes.
Reference range
Negative (blaVIM-2 gene not detected)N/A
No fasting or special preparation required. Sample should be collected prior to initiation of antimicrobial therapy whenever possible to maximize detection yield
