Internal Test Code:- OVAR


Indication:Autoimmune Premature ovarian failure.

Background: Cytochrome P450 enzymes involved in steroid biosynthesis are the targets of autoimmune attack against steroid producing cells. Antibodies that react with more than one of the 3 tissues tested (adrenal, ovarian and testicular) react with enzymes common to the hormonal synthetic pathways and are generally termed “steroid cell antibodies”. Ovarian antibodies are directed against P450scc enzyme. These antibodies may be cross-reactive with other steroid cell antigens. Several rare autoimmune endocrinopathy syndromes (PGA1, PGA2) are associated with these antibodies along with idiopathic Addison’s disease, premature ovarian failure, premature testicular failure and rare autoimmune pituitary failure. Absence of antibody does not rule out an autoimmune endocrinopathy, Results should be used with clinical symptoms, clinical history and other available data.
