No significant differences were found in the concentrations of serum albumin, total bilirubin, uric acid and iron between the endometriosis (median values: 4.48 g/dL, 0.47 mg/dL, 4.72 mg/dL and 82.00 μg/dL, respectively), non-endometriosis (median values: 4.18 g/dL, 0.54 mg/dL, 4.53 mg/dL, and 124.00 μg/dL, respectively) and control (median values: 4.22 g/dL, 0.52 mg/dL, 4.50 mg/dL and 91.00 μg/dL, respectively) groups. The gene discussed is ALB; the disease is endometriosis.
