The primary goal of our study was to determine the ability of each of the analyzed parameters (TAS, FRAP, albumin, total bilirubin, uric acid, iron, SIRT3, SIRT5, SIRT6, telomerase and AOPP) to differentiate patients with advanced endometriosis from the group of healthy women and the group of women without endometriosis (non-endometriosis), but with other benign gynecological disorders. The gene discussed is SIRT3; the disease is endometriosis.
