The serum levels of γ-glutamyl transpeptidase (GGT) (P = 0.026), albumin (ALB) (P = 0.018), and A/G (albumin/globulin) (P = 0.022) levels and blood urea nitrogen (BUN) (P = 0.021) were significantly different between hypertension patients and non-hypertension patients (Table 2). This evidence concerns the gene ALB and hypertensive disorder.
