In a neonate suspected of DiGeorge Syndrome, which two tests are indicated to be ordered immediately?

In cases of suspected DiGeorge Syndrome, it is crucial to assess for abnormalities associated with this condition, particularly concerning the parathyroid glands and cardiac anomalies. The correct tests to be ordered immediately include a serum calcium level and an echocardiogram.

Measuring the serum calcium level is essential because individuals with DiGeorge Syndrome frequently exhibit hypoparathyroidism, which can lead to hypocalcemia. This electrolyte imbalance can pose significant risks, including seizures and cardiac complications, necessitating prompt intervention.

An echocardiogram is also critical in this context since DiGeorge Syndrome is associated with a variety of congenital heart defects, such as conotruncal defects, including tetralogy of Fallot and truncus arteriosus. Early identification of these cardiac anomalies is vital for management and surgical planning.

Thus, performing these two tests provides a comprehensive evaluation to identify potential life-threatening conditions that can arise due to the syndrome's implications on calcium metabolism and heart structure.
