ACE and Hypercalcemia: g/dl: gram per deciliter; mg/dl: milligram per deciliter; mmol/L: millimole per liter; pg/ml: picogram per milliliter; ng/dl: nanogram per deciliter; U/L: unit per liter; pmol/L: picomole per liter; PTH: parathyroid hormone; ACE: angiotensin-converting enzyme The laboratory findings were consistent with severe hypercalcemia (calcium 15.3 mg/dL) and elevated 1,25-dihydroxy vitamin D (193 pg/mL), both of which are commonly associated with conditions such as sarcoidosis or lymphoma.
