Other possible diagnostic markers for endometriosis include CA-125 (Hirsch et al., 2017), VEGF, microRNAs, immunologic markers, and soluble ICAM levels (Acimovic et al., 2016; Vodolazkaia et al., 2016; Gagné et al., 2003; Matalliotakis et al., 2001; Kuessel et al., 2017; Mosbah et al., 2016; Bohler et al., 2007; Drosdzol-Cop et al., 2012; Wu et al., 2015); however, none of these can identify endometriosis patients with both high sensitivity and specificity. Here, VEGFA is linked to endometriosis.
