Important Information Regarding GeneDx Test Menu Changes 

In March, selected tests will be retired from the GeneDx catalog. These changes to our test menu are an important step toward achieving our mission: delivering personalized and actionable health insights to inform diagnosis for all patients who can benefit. We remain steadfastly focused on this goal and believe the best way to achieve it is through exome and genome sequencing. 

Below you will find a detailed list of the tests impacted and key dates for last order and sample acceptance.

Why the focus on exome and genome sequencing?

At GeneDx, we believe the most efficient way to find a diagnosis is through exome and genome sequencing. With their more comprehensive scope, exome and genome sequencing are more likely to deliver a genetic diagnosis than multigene panels.1-4 What’s more, they report fewer variants of uncertain significance than panels4 and the data can be reanalyzed. For many indications, ordering an exome or genome test leads to more answers for more patients—unlocking new treatments and ultimately reducing healthcare expenses.5
