Lab tests to evaluate hypocalcemia
What laboratory tests are helpful in the evaluation of hypocalcemia?
Ionized calcium will confirm true hypocalcemia.
Serum PTH is the most helpful test in evaluating hypocalcemia and should assist in differentiating between conditions associated with low or elevated PTH levels.
Further, serum magnesium, phosphorus, and creatinine, 25D, and 1,25D can be obtained, as suggested by the patient’s clinical and medication history.
