For Nutritionists, Dietitians & Health Coaches
Start with the diet your client already has.
A structured framework for personalized nutrition.
Use the DII® assessment in your first session to see how your client's current eating pattern scores on the inflammatory scale. Identify practical changes within that familiar pattern, then add blood biomarker insights to inform follow-up conversations.
Start with their diet. Build a plan around their real life.
Begin with a research-backed DII® assessment in your first session. Pair dietary insights with OneTest for Longevity biomarker results for a structured way to guide and revisit your recommendations.
Chronic low-grade inflammation can develop without obvious warning signs. It may be associated with concerns clients frequently bring to their practitioners, including:
Measuring inflammation-related biomarkers gives you objective information that symptoms and lifestyle trackers alone cannot provide.
A Dual-Track Methodology
See what is happening — and why it may be happening
Bring dietary-pattern insights and blood biomarkers into the same conversation, so your recommendations respond to the client's actual habits and results.
A specially developed blood biomarker panel provides objective insights into your client's inflammation and metabolic health.
The validated Dietary Inflammatory Index (DII®) analyzes the client's overall dietary pattern — not just calories or isolated nutrients — to show how their diet may be influencing inflammation.
Together, these assessments help you understand:
More Than a Test Result
A structured system for working with every client
Start with a DII® assessment in the first meeting. Add biomarker results, recommend manageable changes within the client's existing diet, and revisit their progress over time.
Assess the client's current eating pattern together and use their DII score to begin a focused nutrition conversation right away.
Review the blood results alongside the dietary assessment to inform recommendations and establish a baseline for follow-up.
Build on what your client already eats. Targeted food swaps can feel more manageable than an entirely new diet, helping reduce resistance to the plan.

Why Practitioners Are Adding This
What this does for your business
Differentiation, retention, and credibility — built on validated science.
- Inflammation and metabolic health
- Diet quality (HEI/DII®)
- Protein and nutritional status — important for avoiding muscle loss
- Stand out from generic coaching programs
- Talking points backed by data, not opinion
- Keeps clients engaged and re-booked
- Earn referral commission on every test
- No new certification required
- Physician telemedicine support included
See the pattern. Measure the baseline. Follow the change.
The value is in the client's own results: which parts of their diet shape their DII® score, what the blood panel measures, and how both look at follow-up.
Affordable For Your Clients
Two easy ways to order
A price point your clients can say yes to — buy once, or subscribe and save with a cadence that matches your 90-day protocol.
At $39/month, subscribing works out to $468/year for 4 tests, versus $756 buying four one-time kits — with a quarterly testing rhythm. Partner pricing may differ from list price; details are shared once you apply.
The Science
Built on two decades of published, peer-reviewed research.
Developed at the University of South Carolina, the DII connects real blood biomarker response to dietary pattern. Physician telemedicine support is available behind every result.
On timeframe: rather than a generic "reset in X days" claim, this is anchored to the protocol's actual cadence. Dietary intervention effects are detectable within 3-month periods. Large population studies have found lower DII scores associated with lower relative all-cause mortality risk — directionally supporting the value of shifting pattern toward anti-inflammatory. Individual results vary.

FAQ
Common questions from practitioners
Is this a diagnostic test?+
No. OneTest for Longevity is intended for educational and wellness purposes and is not a substitute for medical advice or diagnosis.
Can I run the DII assessment in my first session, before the blood test?+
Yes. The dietary assessment can be completed live in your first meeting, giving you and your client a DII score showing how their current eating pattern ranks on the inflammatory scale before any blood is drawn.
Do I need special training to interpret the reports?+
No new certification is required. Reports are built to be read and acted on directly.
Is physician support included if a result needs medical interpretation?+
Yes. Telemedicine physician support is available behind every result.
Can I use this with clients on GLP-1 medications?+
Yes — it's a growing use case. GLP-1 therapy drives weight loss, but the scale can't show whether that loss is coming from fat or lean muscle, or whether appetite suppression is quietly lowering diet quality. Tracking inflammation, dietary pattern (HEI/DII), and albumin (a protein/nutritional status marker) each cycle gives you signals beyond weight to guide the client's plan.
How does the referral commission work?+
You'll earn a commission on client tests ordered through your referral link. Full commission structure and payout schedule are shared when you apply.
What does it cost me? What does it cost my client?+
There's no cost to join as a partner. Clients can buy a single test for $189, or subscribe for $39/month (4 tests per year) to match the quarterly re-test cadence. Partner pricing may differ from list price — details are shared once you apply.
