(i) Once CKD is diagnosed, it is recommended to monitor eGFR and albuminuria at least once a year; (ii) high-risk patients: monitor these measures at least twice a year; (iii) extremely high-risk patients should be monitored at least three times a year (laboratory screening includes measurement of complete blood count, basic metabolic panel, serum albumin, phosphate, parathyroid hormone, 25-hydroxyvitamin D and lipid panel). Here, PTH is linked to chronic kidney disease.
