PTH and anemia (phenotype): Three additional questions concerning screening and management of anemia and SHP were posed: (1) is it a complication of CKD;(2) at what stage of CKD do you screen for it; and (3) at what level of hemoglobin (Hgb) or parathyroid hormone (PTH), respectively, do you start therapy or ask for a consultation when faced with a patient whose creatinine clearance is 40 ml/min.
