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. This evidence concerns the gene SIRT5 and endometriosis.
