PTH and Hypercalcemia: The blood testing revealed normochromic normocytic anemia of 10.7g/dL (N 12.5-16.0g/dL) and a worsened renal function, with urea of 54.2mg/dL (N 8-23mg/dL) and creatinine level of 2.1mg/dL - baseline value of 1.6mg/dL (N 0.5-0.9mg/dL), in addition to multiple electrolyte disorders - hyponatremia, hypokalemia, hypochloremia, hypophosphatemia, with hypercalcemia being the most relevant of them all, with a corrected calcium of 16.5mg/dL (N 8.4-9.7mg/dL), along with a very high PTH value of 1240 pg/mL (N 15-65pg/mL).
