What is a necessary condition before performing a Urine Glucose Test on an infant?

Before performing a Urine Glucose Test on an infant, it is essential to have verbal consent from a guardian. This is because infants cannot provide consent themselves, and guardians, usually parents, are legally responsible for medical decisions regarding their child's health. Verbal consent allows healthcare providers to communicate with guardians about the test and its purpose, ensuring informed consent is obtained even if it’s not always documented in writing.

The other options, while they address different aspects of patient care, do not reflect the necessary condition for proceeding with the Urine Glucose Test specifically in the case of an infant. Written consent could certainly be sought in some situations, but verbal consent is typically sufficient for routine tests. Fasting requirements are not standard for a Urine Glucose Test, so ensuring the infant is fasting or confirming fluid intake may not be applicable or necessary based on the specific guidelines for this test.
