The correlation between pentosidine (both corrected for albumin and not corrected for albumin) and albuminuria in 250 patients in whom albuminuria was analyzed: 38 patients with CKD 3–4 and 212 CKD 5-ND patients had albuminuria of 1542.5 (145.3–6094.6) and 352.5 (4.0–2001.7) mg/L per 24h respectively. Here, ALB is linked to chronic kidney disease.
