On biochemical examinations sodium was 143 mmol/L, glucose 4.1 mmol/L, urea 5.7 mmol/L, total serum proteins 43 g/L, albumin 22 g/L, alanine aminotransferase 227 IU/L, aspartate aminotransferase 181 IU/L, γ-glutamyl transferase 397 IU/L, C-reactive protein 89.3 nmol/L, erythrocyte sedimentation rate 80 mm/hour and creatinine 31.8 µmol/L.
