ALB and hyperlipidemia: Laboratory investigations revealed a normal serum creatinine of 1.0 mg/dl (corresponding to 88 μmol/l), a serum albumin of 24 g/l, hyperlipidemia with a cholesterol level of 514 mg/dl (corresponding to 13.3 mmol/l), and nephrotic proteinuria with a urinary albumin-to-creatinine ratio of 5.4 g/g (corresponding to 610 mg/mmol) (Figure 2c).
