Our Tests

The following questions are specific to PGx and NGx testing.

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.

What is an adverse drug reaction (ADR)?

ADR is the term used to describe an unexpected, negative response to medication. There are many different ways to experience an ADR, from mildly uncomfortable side effects to severe complications that could lead to long-term health problems. Research indicates that many ADRs may be preventable with proper precautions.

What medications are covered by the Precision Medication Test?

The Precision Medication Test encompasses over 100+ approved prescription and OTC medications.

Why isn't my medication listed in your medication directory?

PlexusDx provides one of the most comprehensive reports in the field. If your medication isn't included, there's insufficient clinical evidence supporting the identification of genetic variants. Our reports incorporate the latest clinical guidance from reputable organizations, including the Clinical Pharmacogenetics Implementation Consortium (CPIC) and the Federal Drug Administration (FDA).

Please note that it is important to consult with your provider before making any changes to your medications. This is a clinical test intended to be shared with your provider.

What is Nutrigenomics (NGx)?

Nutrigenomic (NGx) testing investigates the influence of genetic makeup on nutrient needs. The generic advice to “eat right and exercise” means different things depending on your genetics. This test can help you outline what changes you can make to your daily habits that can impact your weight, energy, and overall health.

Is nutrigenomics (NGx) right for me?

Everyone can benefit from knowing how your genetics influence your body’s response to nutrition, providing you with a lifetime of guidance.
