What laboratory test is done to check for infection prior to transferring a neonate?

The laboratory test used to check for infection prior to transferring a neonate is a blood culture. Blood cultures are essential in detecting the presence of bacteria or other pathogens in the bloodstream, which is crucial, especially in neonates who can rapidly develop severe infections. Since their immune systems are immature, timely identification of an infection can lead to early intervention, improving outcomes and reducing the risk of complications.

In the context of the patient transfer process, ensuring that a neonate does not have an active infection is critical for the safety of both the patient and the receiving facility. This is why obtaining a blood culture is a standard practice in such scenarios, as it provides vital information about potential sepsis or other systemic infections that could affect the neonate.

The other tests mentioned do not specifically assess for infection risks. Blood glucose tests and renal function tests evaluate different health aspects, such as metabolic and kidney function, while a CT scan is primarily used for imaging and would not be an appropriate initial assessment for infection.
