Laboratory test results revealed severe hypercalcemia (Ca = 24.3 mg/dl, reference range (rr): 8.5–10.2), hyperphosphatemia (P = 5.1 mg/dl, rr: 2.5–4.5), mild hypomagnesemia (Mg = 1.5 mg/dl, rr: 1.6–2.3), elevated serum creatinine (Cr = 1.53 mg/dl), elevated C-reactive protein (CRP = 31 μg/ml, rr: 0–5), increased white blood count (WBC = 22.700/μL), and low TSH level (TSH = 0.271 μU/ml, rr: 0.4-4). Here, CRP is linked to hypercalcemia disease.
