Calcium disturbances may be mirrored by magnesium, as seen in hypocalcemia with hypomagnesemia or hypercalcemia with hypermagnesemia. Infants of diabetic mothers and infants with fetal growth restriction may present with hypocalcemia, hypomagnesemia, or both. Abnormalities in serum values for Ca2+ and Mg2+ are of concern in any infant and warrant further investigation.
