Diagnose autoimmune disorders with the Anti-Cardiolipin Antibodies (IgG and IgM) Blood Test.
Anti-cardiolipin antibodies (ACA) IgM and IgG are used to help diagnose certain autoimmune disorders, particularly antiphospholipid syndrome (APS). These antibodies target a specific type of phospholipid called cardiolipin, which is a component of cell membranes. Antiphospholipid syndrome increases the risk of deep vein thrombosis, pulmonary embolism, heart attacks, strokes, and pregnancy complications including recurrent miscarriages. These antibodies are therefore often checked for when things occur, especially when they occur unexpectedly, repeatedly, or at an unusually young age. It is worth noting that a positive ACA test does not necessarily confirm the presence of APS, as these antibodies can also be present in other conditions or even in healthy individuals. Therefore, additional clinical assessments and follow-up investigations are necessary for accurate diagnosis.

Who Is This For?
People experiencing unexplained digestive issues, skin problems, or chronic fatigue that may be food-related. Anyone with known allergies who wants comprehensive mapping of their triggers. Parents investigating potential food sensitivities in children. People considering an elimination diet and wanting data to guide which foods to remove.
What's Included
Preparation Required
No fasting required. Continue eating your normal diet for at least 2–4 weeks before testing — avoiding suspected trigger foods can cause false negatives. Inform the clinic of any antihistamines or immunosuppressants you're taking, as these can affect results.
Biomarkers Tested
2Measures the level of IgM antibodies targeting cardiolipin, a phospholipid in cell membranes. Elevated levels may indicate autoimmune disorders.
Immunoglobulin G (IgG) is the most common type of antibody in the blood, important for fighting bacterial and viral infections.
