Does newborn infection require a skin test for penicillin?

Patient's question:

Patient Age: Newborn
Main Symptoms: Fever, Rash
Onset Time: Not Specified
Laboratory Test Results: Streptococcal Infection
Previous Treatment and Effect: None

Doctor's answer:

Penicillin is the safest, most effective, and most ideal first-line drug for treating neonatal infectious diseases. Streptococcus is sensitive to penicillin and can be used as a first-line drug. A skin test for penicillin has little reference value for neonatal medication. The reason is that among penicillin allergic reactions, anaphylactic shock of the rapid type is the most severe, and neonates lack antibodies that can trigger allergic reactions. Furthermore, neonates rarely come into contact with penicillin, and their bodies will never produce additional antibodies or autoimmune active substances.
