Find the right path to genetic testing for your family

Testing a person's DNA and then comparing it to two biologically related family members is called trio testing.

‍

Trio testing is valuable because it:

• increases the chance of finding the gene change causing the symptoms
• decreases the chance of unclear or uncertain findings

‍

That's because everyone has changes in their genes. Comparing the DNA of relatives makes it easier to figure out which genetic changes are causing your symptoms (and which are not).

‍

Samples from biological parents can provide the most information. However other blood-related family members may also be considered if both biological parents are unable to provide a sample.

Genetic testing looks at our genes which are the instructions that tell our bodies how to develop and function. Sometimes changes in our genes (also called genetic variants) cause our bodies to grow or develop differently than expected. Genetic testing may be able to find these gene changes. That knowledge can help determine:

‍

• how to best manage or treat a condition or prevent complications related to a genetic diagnosis
• what to expect for the future
• which additional resources and support may help

Only licensed healthcare providers can order testing directly through GeneDx.
