I was told that even though my cardiolipin igm has been high 3 times over a 100 each time since nov. i should not worry because my igg is normal.true?

Depends....: The anti-cardiolopin ab is a screening test; if (+) it does not necessarily mean you have a clinical disease. In addition, there are other tests that are thought to be more sensitive and specific for the diagnosis of antiphospholipid syndrome. Have you had the beta 2 glycoprotein test? Have you ever had 2 documented episodes of blood clots? If no clots and beta 2 (-), then "not to worry".
