Key takeaways
- Nutrigenomic testing works best as a provider led service, not a product on a shelf.
- A licensed provider decides who's a candidate, orders the test, reviews the report and talks it through.
- Reports describe genetic tendencies. They are not diagnoses.
- Nutrigenomics and pharmacogenomics are different, so choose a testing company on lab credentials, validation, report writing, privacy and support.
- Consent and privacy need to be settled before the first test is ordered.
This guide covers the structure: what nutrigenomics is, how it differs from pharmacogenomics, how to choose a testing company, how to build the workflow and how to explain results without overpromising. It uses RevMed's NGX panels as the working example, because that's the line we introduce clinics to. Every clinical decision stays with your provider.
How do clinics add nutrigenomic DNA testing, and what can it tell clients?
Nutrigenomic testing fits best when a clinic treats it as part of a conversation, not as a product on a shelf. The test gives the provider a set of genetic insights. The provider decides what, if anything, those insights mean for the client in front of them, alongside history, lifestyle, labs and goals.
What can a report tell a client?
A good report gives three things:
- Which genes were looked at. Each report names the genes in its panel and what each gene is generally associated with.
- The client's variants and an impact rating. The report shows which versions of each gene the client carries and how much the lab thinks that variant may matter.
- Plain language context. A short explanation the provider can use to start the conversation.
What it can't tell a client is just as important. A nutrigenomic report doesn't say a person has a condition. It doesn't say a person will develop one. It doesn't replace a medical evaluation, and it doesn't prescribe anything. Genes are one factor among many, and the provider puts them in context.
RevMed's own NGX materials say this directly. As RevMed puts it: "Genes are one factor alongside diet, lifestyle and environment." And: "Reports show predisposition, not diagnosis." And: "Results are designed to be reviewed with a practitioner."
The steps to add it
Most clinics follow roughly the same order:
- Name a clinical owner. One licensed provider owns the testing service, decides who's a candidate and reviews every report.
- Choose the lab and panels. Pick a testing company using the criteria later in this guide, then choose a small number of panels that match the clients you already see.
- Write the consent and the script. A consent form that explains what the test is and isn't, how data is handled and who sees results. A short front desk script that describes the service without describing outcomes.
- Set up ordering, collection and results. Decide how kits are ordered and stored, who collects the sample, how it ships and where reports land in your EMR.
- Build the results visit. A scheduled visit where the provider reviews the report with the client. This is the core of the service.
- Post a cash fee. Testing is offered as a cash pay service with a clear posted fee and a signed financial policy.
- Open small and review. Offer it to a limited group first, then look at what took too long, what confused clients and what the team needs.
None of this needs new space. It needs an owner, a clear script and a results visit that the provider is comfortable running.
What is nutrigenomics?
Nutrigenomics is the study of how genes and nutrition interact. Researchers look at how variations in a person's genes may influence how their body handles nutrients, and how nutrients and diet may in turn influence how genes are expressed.
You'll also see the word nutrigenetics. It's often used for the narrower question of how a person's genetic variants relate to their response to diet. In everyday clinic use, the two terms are often blended, and many testing companies use "nutrigenomic testing" for both. The important point for staff is the same either way: these tests look for genetic tendencies, not diseases.
What does a nutrigenomic test actually look at?
Most tests look at single letter differences in DNA, called variants, in genes that research has linked to things like nutrient handling, metabolism or response to activity. The lab reads the client's variants from a sample, often a cheek swab, and compares them with published research.
That last part is why the field needs care. The research behind individual gene and nutrient links varies a lot in strength. Some associations are well studied. Others rest on a small number of studies. A careful report says how confident it is, and a careful provider explains that to the client.
How NGX frames it
NGX is RevMed's nutrigenomic testing line. RevMed puts it this way: "Six DNA tests. One sample."
RevMed's materials describe six panels run from that one sample:
- DNA Health: RevMed calls it the foundation panel, covering whole body wellness areas.
- DNA Diet: diet and activity related genes.
- DNA Sport: performance and recovery related genes.
- DNA Skin: skin related genes.
- DNA Oestrogen: genes involved in how the body builds, uses and clears estrogen, for women and men.
- DNA Mind: genes RevMed describes as relating to cognition and stress response.
RevMed also lists what every report includes. As RevMed puts it, each report includes: "Each gene rated No, Low, Moderate or High impact; Plain-language explanations of what each gene does; Diet, supplement and lifestyle recommendations; Practitioner notes for building the care plan."
Those recommendations are the lab's general suggestions, written for the provider to review. They are not a prescription and they are not a plan on their own. Your provider decides what applies to each client.
RevMed also offers an NGX Genetic Summary. RevMed puts it this way: "The full lab reports run to more than 100 pages. The NGX Genetic Summary turns them into a short, plain-language plan." In practice, treat the summary as a starting point for the provider conversation, reviewed and edited by your provider before anything goes to the client.
Nutrigenomics vs pharmacogenomics: what's the difference?
These two get mixed up, and the difference matters for how you describe your service.
Pharmacogenomics is the study of how genes affect a person's response to medications. The National Human Genome Research Institute describes it as the study of how a person's genes affect their response to drugs. The FDA keeps a public table of pharmacogenomic biomarkers that appear in drug labeling. So pharmacogenomics sits close to prescribing decisions.
Nutrigenomics looks at genes and nutrition, activity and lifestyle. It's about tendencies that may influence how a person responds to food and environment, not about medication choices.
Here's a simple way to keep them apart:
| Nutrigenomics | Pharmacogenomics | |
|---|---|---|
| Main question | How might genes influence response to nutrition, activity and lifestyle? | How might genes influence response to specific medications? |
| Typical use | Wellness and lifestyle conversations led by a provider | Medication selection and dosing decisions by a prescriber |
| What NGX covers | Yes, this is NGX's area | Not described in RevMed's NGX materials |
The practical rule for your team: don't describe a nutrigenomic panel as a medication test, and don't suggest a nutrigenomic result tells anyone which drug to take. If your providers want pharmacogenomic testing, that's a separate decision with its own lab, consent and clinical workflow.
How do you choose a nutrigenomics testing company?
The right lab is the one whose reports your providers trust and can explain. We don't rank labs, and we'd be cautious of anyone who does. Instead, ask every company the same questions.
Lab credentials
Ask where the testing is performed and what certification the lab holds. In the United States, the Clinical Laboratory Improvement Amendments (CLIA) set quality standards for laboratory testing performed on human specimens, and CMS runs the CLIA program. Ask for the lab's CLIA certificate number and any accreditation, and check it yourself.
Validation and method
Ask how the lab reads the DNA, how it checks its own quality, and whether it has validated its testing method. Ask what happens when a sample fails or a result is unclear. A lab that answers these plainly is easier to work with.
How reports are written
This is where labs differ most. Read a sample report before you sign up. Ask:
- Does each gene finding say how strong the research behind it is?
- Is the language about tendencies, or does it read like a diagnosis?
- Are recommendations framed for a provider to review, or written as instructions to the client?
- Would your provider be comfortable handing this to a client?
Data and privacy
Ask how genetic data is stored, who can access it, how long it's kept and whether it's ever shared or sold. Ask how a client can request deletion. Your consent form should match the answers.
Ordering and support
Ask who can order, how kits ship, how long reports take and how results are delivered. Ask whether there's clinical support for your providers when a report raises questions.
Our cluster article, How to choose a nutrigenomics testing company for your clinic, turns these into a checklist.
Are nutrigenomic tests accurate?
Accuracy depends on the lab and the method. There are really two questions inside this one. First, does the lab read the DNA correctly? That's about lab quality, certification and validation. Second, does a given variant mean what the report says it means? That's about the strength of the research behind each gene finding, which varies.
We don't quote accuracy figures, because they depend on the lab, the method and the gene. Ask each company for its credentials and validation, read how reports are written and let your provider judge.
How do you explain results to clients?
The results visit is where this service succeeds or fails. A client who leaves understanding that a report shows tendencies, and that their provider has put those in context, has been served well. A client who leaves thinking they've been diagnosed has not.
Before the visit
Your provider reads the full report first. They note anything that needs a closer look, decide what's worth discussing and decide what isn't relevant for this client. Results are interpreted by the provider, not by the front desk, not by a sales team and not by us.
During the visit
A simple structure helps:
- Start with what the test is. "This report looks at genes that may influence how your body responds to food, activity and environment. It shows tendencies. It isn't a diagnosis."
- Set the context. Genes are one factor. History, lifestyle, labs and goals matter too.
- Walk through a few findings. Pick the ones the provider thinks are relevant. Explain the impact rating in plain words.
- Talk about what the provider recommends, if anything. Any next step is the provider's clinical decision, and any treatment is prescribed and supervised by your licensed provider.
- Invite questions and document. Note what was discussed in the chart.
Words that help, words to avoid
Say: "tendency", "may influence", "one factor", "something to keep in mind", "let's talk about what this means for you."
Avoid: "you have", "you will", "this proves", "your genes mean you need", any promise of a result, and any suggestion that a report replaces medical care.
The FTC expects health claims to be truthful, not misleading and backed by competent and reliable scientific evidence. That applies to how a clinic markets testing as well as how it talks about results.
When results raise a concern
Sometimes a client reads something in a report that worries them. The answer is the same every time: the provider reviews it with them, and if anything needs further evaluation, the provider decides how to handle it. Staff shouldn't interpret, reassure or speculate.
Our planned cluster article, How to read nutrigenomics results with clients without overpromising, will go deeper on this.
Who does what in a testing service?
Clear roles keep the service safe and simple.
- Provider: decides candidates, orders, reviews reports, runs the results visit, documents and makes every clinical decision.
- Nurse or MA: sample collection and kit handling, as delegated within your state's rules.
- Front desk: booking, consent forms, payment and general questions using an approved script.
- Practice manager: kit inventory, shipping, report routing and the schedule.
If a client asks the front desk what their results mean, the answer is always: "That's a great question for the provider."
How does consent and privacy work?
Genetic information is personal, and clients deserve to know how it's handled. Your consent form should cover:
- What the test looks at and that it shows tendencies, not diagnoses.
- Who performs the test and where the sample goes.
- Who sees the results and how they're stored.
- Whether data is shared, and how a client can ask for deletion.
- That results will be reviewed with the provider.
Federal law also limits some uses of genetic information. The EEOC enforces the employment provisions of the Genetic Information Nondiscrimination Act (GINA). Your counsel can tell you what applies to your practice and how to describe it.
Have your consent reviewed by counsel before you offer testing.
How do you price and position the service?
Testing is a cash pay service. Post a clear fee, explain what's included (the test and the results visit) and have clients sign a financial policy. We don't publish pricing here.
Position it as an add on to care the client already receives, not as a standalone answer. Describe the service, not the result. "A DNA test with a provider review visit" is accurate. Anything that promises a change in health, weight or performance isn't.
How do clinics order NGX tests through RevMed?
NGX tests are ordered from the same RevMed account clinics use for supplies. RevMed says every test is available to order through the RevMed Shop.
The order of events:
- Open your clinic account through our Partner Link. We make the introduction and help you get set up.
- Get verified through RevMed. RevMed sells only to verified providers. Once you're verified through RevMed, existing practices can be ordering within about 48 hours.
- Order tests and supplies from one source. Products come from licensed, vetted pharmacy and laboratory partners. RevMed also says ordering through one source means a lower cost per item.
- Collect the sample and ship it following the kit instructions.
- Your provider reviews the reports and runs the results visit.
Ordering, fulfillment and lab support run through RevMed. If you're adding testing as part of a broader service line, RevMed's launch team can help with the setup on a fixed 60 day calendar. See the clinic launch program and the NGX DNA testing page.
We're based in Raleigh and work with clinics across the Triangle. Our part is the account, the introduction and checking in at the milestones that matter.
What are the common mistakes?
A few patterns to steer clear of:
- Selling the test without the visit. A report without a provider review invites misreading.
- Diagnostic language in marketing. Phrases that suggest the test finds or rules out conditions.
- Outcome promises. Anything implying a result from acting on a report.
- Staff interpreting results. Only the provider interprets.
- Too many panels at once. Start with the one or two that match the clients you already see.
- Skipping the privacy conversation. Clients should know where their data goes.
