When Should Infants Get Blood Tests for Syphilis? - Urology

When it comes to testing infants for syphilis, the timing and necessity of such tests can vary based on several factors, including maternal health and risk factors during pregnancy. In general, the Centers for Disease Control and Prevention (CDC) recommends that all pregnant women be screened for syphilis at the first prenatal visit. If a mother is diagnosed with syphilis during pregnancy, her infant should be tested for the infection.

For infants, the recommended time to conduct a blood test for syphilis is typically at birth or shortly thereafter, especially if there are concerns about maternal syphilis infection. If the mother was not screened during pregnancy or if there are any signs of congenital syphilis (such as rash, fever, or other symptoms), the infant should be tested as soon as possible. The blood test can be performed using a sample from the infant's heel (heel prick), which is a common method for newborn screenings.

If the infant is born to a mother who is known to be infected with syphilis, the infant should be tested at birth and again at 3 to 6 months of age, as congenital syphilis can manifest later. The testing is crucial because untreated syphilis in infants can lead to severe complications, including developmental delays, bone deformities, and other serious health issues.

In cases where the mother did not receive prenatal care or syphilis screening, it is advisable to consult with a pediatrician or healthcare provider as soon as possible. They can assess the infant's risk factors and determine the appropriate timing for testing. It is also important to note that if the infant shows any signs of infection, immediate testing and treatment should be initiated.

In summary, infants should ideally be tested for syphilis at birth, especially if there are any risk factors or maternal history of syphilis. If the initial test is negative but there are ongoing concerns, follow-up testing at 3 to 6 months may be warranted. Early detection and treatment are key to preventing the serious consequences of congenital syphilis.
