ALB and Hypokalemia: It should be noted, however, that in our cohort the prevalence of hypokalemia (potassium ≤ 3.5 mmol/L) and hypocalcemia (albumin-corrected calcium ≤ 2.20 mmol/L) was relatively low (4.8% and 7%, respectively), and no severe cases (potassium ≤ 3.0 mmol/L; albumin-corrected calcium ≤ 2.0 mmol/L) were observed.
