Answer

Newborns with ambiguous genitalia should be closely observed for symptoms and signs of salt wasting while a diagnosis is being established. Clinical clues include abnormal weight loss or lack of expected weight gain. Electrolyte abnormalities generally take from a few days to 3 weeks to appear, but in mild forms of salt-wasting adrenal hyperplasia, salt wasting may not become apparent until an illness stresses the child.
