This test checks for problems similar to lupus and rheumatoid arthritis or other similar immunological diseases which are associated with pregnancy losses or infertility. This test becomes weakly positive in women with infertility and in women with recurrent pregnancy losses. This antibody causes inflammation in the body or in the uterus when a baby attaches. It is usually reported as ANA positive with at titer of 1:40 or higher with a speckled pattern. This pattern is not typical of lupus or rheumatoid arthritis or other immunological disorders.
A blood test that is used in the evaluation of possible lupus or other connective tissue disorders. When the ANA is positive, it indicates that someone may have an autoimmune disorder, but by itself it cannot make the diagnosis for sure.
Anti-nuclear Antibody - Autoantibodies against various cell nuclear components. See "How is Lupus Diagnosed?", "I've Heard of the Lupus Criteria - What's That?", "I Have a Positive ANA but I'm Told I Don't Have Lupus", "Can a Lupus Patient have a negative ANA titer?"
Association of National Advertisers.
