What is Pharmacogenomics (PGx)?

Pharmacogenomics explores how individual genetic makeup influences drug responses, addressing questions like medication efficacy, understanding drug effects before consumption, and why certain drugs might cause adverse reactions.

Is PGx testing right for me?

Everyone can benefit from the information gleaned from a PGx test. For individuals who are currently taking medications that are ineffective or come with unwelcome reactions, PGx testing can provide data to inform medication decisions and dosing, so you can focus on feeling your best.

Even if you're not currently on any medication, we advise undergoing a PGx test, a one-time requirement. This proves beneficial for future medication needs, allowing you to share your results with your healthcare provider. Tailored treatment based on your DNA ensures personalized care when necessary.

How does PlexusDx handle my DNA sample?

Your genetic data is utilized solely for report processing, with no storage or use beyond this requirement. Rest assured, we promptly discard your sample after processing is complete.
