To the Editor: Regarding the case of tetany presented by Drs. Shaheen and Merugu in the June 2013 issue of Cleveland Clinic Journal of Medicine (pages 360–362), their clinical discussion was right on, but they did not mention the clinical use of and need for ionized calcium levels in a case like this and the follow-up to confirm this was not a patient with latent hypoparathyroidism.
There is often a major discrepancy between the total calcium (no matter how it is “corrected”) and the free (ionized) calcium value, and the need to follow it during the correction phase of both hypercalcemia and hypocalcemia is critical.
