Laboratory assessment (Table 1) showed normocytic normochromic anemia (Hb: 8.7 g/dL), elevated parathyroid hormone (PTH: 885.0 pg/mL), hyperphosphatemia (6.6 mg/dL), total serum calcium of 9.0 mg/dL (corrected calcium: 10.2 mg/dL), hyperuricemia (9.6 mg/dL), hypoalbuminemia (2.5 g/dL), hypoproteinemia (5.3 g/dL), and hypokalemia (3.0 mEq/L). Here, PTH is linked to anemia (phenotype).
