In contrast, the pre-ESRD CKD disease management program performs follow-up for hemoglobin (Hgb), blood urea nitrogen (BUN), serum Cr, and ALB every 3 months; serum total calcium (Ca), phosphate (P), fasting glucose, and HbA1c every 6 months; and serum LDL, uric acid, sodium (Na), potassium (K), triglyceride (TG), and urine PCR every 12 months. Here, ALB is linked to chronic kidney disease.
