About
OneTest for Longevity is an at-home test for people who want a practical read on inflammation and diet quality. It measures 11 biomarkers, including hs-CRP, ApoB, ApoA1, LDL, triglycerides, TSH, uric acid, vitamins B12 and D, albumin, and alkaline phosphatase. It then combines those lab results with the Dietary Inflammatory Index and Healthy Eating Index, so the report can show both the downstream physiology and the upstream eating pattern. IBM watsonx.ai turns the combined signal into chronic-disease risk estimates and food-level recommendations.
Medical authorization is required to place the order. You can use your own clinician, or use the company's third-party telemedicine authorization service for $20 once the current free launch promotion ends. The authorization clears the test order; the product does not include a scheduled one-on-one physician review of results. Results are delivered as written reports with AI-generated dietary guidance that can be shared with your own clinician.
What to Know
Signature approach
The product is built as a diet-to-biomarker feedback loop. A small at-home blood sample measures inflammation-linked biomarkers, while the online DII survey scores 45 dietary components from anti-inflammatory to pro-inflammatory. The Healthy Eating Index adds a second diet-quality lens. Together, the reports help users see whether the way they eat is lining up with the inflammatory markers in their blood.
What sets it apart
- Focused inflammation panel. The product stays centered on inflammation, lipids, thyroid signal, vitamins, and diet quality instead of trying to be a full executive lab panel.
- Academic dietary scoring. The Dietary Inflammatory Index was developed at the University of South Carolina and is backed by a large peer-reviewed literature base.
- Actionable food guidance. IBM watsonx.ai translates the blood and diet scores into personalized food recommendations instead of leaving users with raw lab values alone.
- Quarterly tracking option. The subscription supports repeated testing for users who want to see whether diet changes are moving their biomarkers.
Before You Order
- Use it for the right job. This works best as an inflammation and diet feedback test. Pair it with a broader lab panel if you also want glucose control, insulin resistance, hormones, Lp(a), advanced lipids, or biological-age markers. - Decide whether you will retest. A single $189/mo test is enough for a baseline. The $39/mo subscription is mainly useful if you want quarterly trend tracking after changing diet or lifestyle. - Confirm final checkout costs. The collection kit and medical authorization are included during launch promotion, but may become add-ons after the promotion ends. - Bring results to your own clinician when needed. The reports are designed to be shared with your own clinician; the product does not include a scheduled results-review visit.

This is not a broad executive lab panel. It does not include fasting insulin, HbA1c, glucose, sex hormones, cortisol, Lp(a), LDL particle count, epigenetic age, telomere length, microbiome testing, or genetic screening. Its job is narrower: connect inflammation-linked biomarkers with diet quality and diet-inflammation scoring. Users who want a full metabolic, hormone, or biological-age workup will need an additional test.
Reference ranges methodology
Each of the 11 blood biomarkers is reported against standard clinical reference ranges. The Dietary Inflammatory Index scores diet from -10 to +10, where negative scores lean anti-inflammatory and positive scores lean pro-inflammatory; most individuals fall between -7 and +7. The Healthy Eating Index scores diet from 0 to 100 against federal dietary guidelines. The combined Longevity Panel Report uses IBM watsonx.ai with Granite 4.0 models to turn the lab values, DII score, and HEI score into chronic-disease risk estimates and food-level recommendations.

In practiceReal-world pricing notes, add-ons, and coverage limits.
The baseline test is $189 During the launch promotion, that currently includes the collection kit and medical authorization, so the practical checkout price is $189 After the promotion ends, expect the kit fee and $20 authorization to be added separately. The subscription is $39/mo for quarterly testing, which only makes sense if you want to watch the diet and inflammation scores move over repeated tests. HSA/FSA eligibility is not stated on the product site. The subscription page also shows a $159 one-time row, but the dedicated product page lists $189 as the active one-time price.

Frequently asked questions
What is OneTest for Longevity?
An at-home blood test that measures 11 inflammation-linked biomarkers and pairs them with diet scoring. The report combines blood results, Dietary Inflammatory Index scoring, Healthy Eating Index scoring, and AI-generated food recommendations.
How do I collect my blood sample?
The kit includes a blood-collection device, instructions, and prepaid return shipping. Fasting is required. The product page describes capillary collection; the launch press release describes an upper-arm device that avoids traditional needles.
How long does it take to receive results?
