Laboratory findings on admission showed mild metabolic acidosis (pH capillary blood 7.21–7.26; 7.23 ± 0.02), low serum levels of albumin (18–24 (21.50 ± 2.81 g/L), sodium ((123–129; 126 ± 2.90 mmol/L), potassium (2.1–2.9; 2.45 ± 0.339 mmol/L), calcium (1.02–1.98; 1.59 ± 0.42 mmol/L), magnesium (0.61–0.68; 0.65 ± 0.026 mmol/L) and phosphorus (0.62–0.79 (0.69 ± 0.07 mmol/L), high serum creatinine (96–133; 107.33 ± 13.53 μmol/L) and anemia (Hb 71–98; 85.17 ± 9.67 g/L). This evidence concerns the gene GSTM1 and anemia (phenotype).
