Can genetics predict how much weight I'll lose on a GLP-1 medication?

No. Weight loss outcomes depend on many factors including dose, diet, activity, and adherence. PGx testing does not predict weight loss results — it provides genetic context to discuss with your prescriber.

Will a genetic test tell me which GLP-1 medication to take?

No. Medication selection is a clinical decision made by your prescriber based on your full health history. PGx results are one additional data point in that conversation.

Is GLP-1 genetic testing covered by insurance?

Coverage varies. NextGen PGx offers direct-to-consumer testing at a transparent price so you don't need to wait on insurance approval.

GLP-1 Genetic Testing: Genetic Context for Weight Management Medications

GLP-1 receptor agonists are widely prescribed for weight management and blood sugar control. NextGen PGx pharmacogenomic testing reports genetic variants that have been studied for possible relevance to how the body processes certain medications in this category.

Why genetics may matter with GLP-1 medications

Response to GLP-1 medications varies from person to person. While diet, activity, dose, and consistency all play a major role, researchers continue to study whether certain genetic variants are associated with differences in medication metabolism.

A PGx test does not predict weight loss outcomes or determine the right dose — it provides additional genetic context that you can discuss with your prescriber alongside your full health history.
