Common questions
Get answers to questions about genetic testing, its benefits, and more.
Clinicians can prepare by identifying appropriate patients based on clinical presentation, reviewing current testing guidelines, and partnering with a laboratory experienced in rare and complex conditions. Understanding test selection, insurance considerations, and follow-up care pathways can help integrate genetic testing smoothly into routine practice. Learn more.
GeneDx provides genetic testing and genomic sequencing to help diagnose rare and complex conditions. Our testing supports patients with developmental delay, intellectual disability, epilepsy, autism spectrum disorder, congenital anomalies, and other inherited conditions across pediatric and adult populations.
Many conditions can have similar symptoms but different causes, some of which could be genetic. Exome and genome testing look at over 20,000 genes at once, which could improve the chances of finding an answer. Learn more.
When discussing genetic testing, clinicians can explain how testing may help uncover the cause of symptoms and inform care decisions. Setting clear expectations about possible results, timelines, and next steps can help patients and families feel informed and supported throughout the process. Learn more.
