In this study, we aimed to determine the correlations between coagulation parameters (TT, PT, APTT, and PLT), inflammatory biomarkers [C-reactive protein (CRP), NLR and PLR], compare the differences between patients with endometriomas and patients with non-ovarian endometriosis cysts and without ovarian cysts, and to explore how these parameters can be used as auxiliary biomarkers for diagnosis. The gene discussed is CRP; the disease is Ovarian cyst.
