How Soon Can You DNA Test a Baby After Birth?

The answer to how soon you can DNA test a baby after birth is: whenever you feel comfortable obtaining a DNA sample from your baby.

All you need to do is obtain a DNA test from a testing company that uses a cheek swab. This is the safest and most practical method for collecting DNA from a newborn.

Types of DNA Samples: Which One Is Best for Baby?

There are several ways to obtain a DNA sample:

• Blood
• Saliva
• Cheek swab

While you could get a DNA test with a blood sample, you can get the same results from less invasive methods. A newborn does not produce enough saliva to fill a standard test tube, and some DNA collection methods that rely on liquid saliva are not well-suited for infants.

DNA testing companies that use a stick with a cotton swab on the end (similar to a Q-tip) are the best choice for a baby DNA test. This method is simple, painless, and can be done at home.

How to Obtain a DNA Sample from a Baby

All you have to do to obtain a DNA sample from a baby is to swab the inside of the cheek with the cotton part of the swab included in the kit. This removes enough cells from the inside of the cheek to extract DNA for analysis. The process is quick, gentle, and completely safe for newborns.

Doing a DNA test on your baby is a wise choice. It can uncover important information about your baby's genetic makeup so you can look into preventive measures, if necessary, as early as possible.

Baby DNA Tests for Paternity Information

Many people want to know how soon they can DNA test a baby after birth to confirm paternity. While this is certainly important, there is so much more that can be derived from DNA data. Basic paternity DNA tests only analyze a very small portion of DNA, which means the results cannot be used for anything else, including identifying the risk for diseases, genetic conditions, and many other predispositions that could develop over the course of the baby's life.

The good news is that DNA tests that analyze more of the genome can be used for paternity confirmation and health information at the same time. Sequencing's whole genome sequencing reads 100% of your baby's DNA across over 30,000 genes. The data from it can be used to confirm paternity and also discover many possible genetic predispositions your baby has inherited.
