In our study, considering each transcript separately, promising diagnostic potential to distinguish GDM patients from healthy controls in the time of GDM diagnosis was found for IL6 (AUC 0.844), IL8 (AUC 0.771) and IL18 (AUC 0.714), whereas IL10 does not appear to be a fully satisfactory biomarker on its own (AUC 0.658). The gene discussed is CXCL8; the disease is gestational diabetes.
