ALB and acute kidney injury: Yu et al. reported a higher incidence of AKI in patients with hypoalbuminemia (serum albumin level <3.4 mg/dL) (10.7%) than that in those with normal albumin levels (4.1%) [34], and the results from a meta-analysis of 68,000 participants across a diverse range of settings confirmed that hypoalbuminemia was an independent predictor for the development of AKI [34, 35].
