Do Hospitals Offer Dna Testing After Birth

Summary: DNA testing after birth is a popular practice that can help identify potential risks and genetic disorders. Hospitals often offer this service, and it has become an integral part of newborn screening programs. This article will explore the different aspects of DNA testing that are available after birth.

1. Purpose of DNA Testing After Birth

DNA testing after birth is conducted for multiple reasons. The primary reason is to screen for genetic disorders, which may be inherited or arise spontaneously from a genetic mutation. Newborn screening tests aim to identify infants who may have genetic disorders, so treatment can begin early and prevent complications from arising. The test can also determine if a newborn has predispositions to certain health conditions, such as heart disease or diabetes, and allow parents to prepare accordingly.

DNA testing after birth can also help to establish paternity. If a father is uncertain about his biological relationship with a child, he can request a DNA test to confirm or deny paternity. This can be an important step in establishing legal rights and financial responsibility.

2. Types of DNA Testing

There are two types of DNA testing available after birth: diagnostic testing and predictive testing. Diagnostic testing is used when a medical professional suspects that a child may have a specific genetic disorder based on symptoms and family history. The testing process involves analyzing a sample of the child’s DNA to determine if the disorder is present.

Predictive testing is used when there is a known genetic risk in the family, and parents want to know if their child inherited the risk. This type of testing is typically not done on newborns but can be done any time after birth. Predictive DNA testing does not diagnose a disorder, but rather informs parents about their child’s risk level and helps them make informed decisions.

3. Hospital DNA Testing Protocols

Hospitals have established protocols for newborn screening and DNA testing. In most cases, parents are provided with information about the testing process and given the option to decline. If a test comes back positive for a genetic disorder, the hospital will work with the family to develop a plan for treatment and monitoring.

In cases of paternity testing, hospitals may require a court order before conducting the test. This is to protect the privacy rights of the mother and child and to ensure that testing is done with the consent of all parties.


DNA testing after birth is a valuable tool for identifying genetic disorders and mitigating potential health risks. Hospitals offer this service as part of their newborn screening program, and parents can choose whether to opt-in or decline testing. There are two types of DNA testing available – diagnostic and predictive – each with its own purpose. Hospital protocols govern the testing process to ensure that all parties are informed and have given consent. Ultimately, DNA testing after birth offers peace of mind for parents, sets a foundation for early intervention, and informs critical medical decisions.
