For a result in hand, the free interpreter on this page reads the standard panel against UK guideline thresholds, and Nutri365 adds the context layer over time. ## How it works The reason the options feel so different is that each solves a different problem. The NHS App shows your results with the laboratory reference range but offers no interpretation, which is where most people''s search starts. Testing companies such as Thriva and Medichecks provide a report written against the sample they processed, useful, but tied to buying their test, and static once delivered. General AI chatbots can discuss a result you paste in, but they do not know your history, your other markers or what you take, and the published evidence on AI blood interpretation identifies exactly this missing context as the accuracy gap. ChatGPT Health, the dedicated health product, is not available in the UK: OpenAI''s launch restricted eligibility to users outside the EEA, Switzerland and the United Kingdom, with no announced timeline. Dedicated interpretation tools close the gap differently: they read your result against published thresholds, in the context of everything else they know about you. ## Guideline positions Whatever explains your result, the thresholds that matter in the UK are the guideline ones, and several sit above the flag on standard laboratory ranges: NICE classes adult ferritin below 30 ug/L as iron deficiency while many reports flag only below 15; UK guidance classes vitamin D of 25 to 50 nmol/L as insufficient; and total B12 between roughly 180 and 350 ng/L is an indeterminate zone where guidance points to second-line testing rather than reassurance. A result printed as normal can still meet a guideline definition of deficiency, which is why interpretation against guideline thresholds, rather than reference ranges alone, is the standard this library applies. Confirmed deficiencies are a GP conversation first, whichever tool surfaced them. ## Practical framework Matching the tool to the job. If you only need to see your results, the NHS App does that free. If you have not tested yet and want a report included, Thriva and Medichecks bundle one with their panels. If you hold a result now and want a free read against UK guideline thresholds, the interpreter on this page reads the standard nutritional panel, ferritin and the iron picture, vitamin D, B12 and folate, in your browser, with nothing stored. And if you want interpretation that carries context, your history, your other results, your tracking data, how you have been feeling, and what you already take, that is what Nutri365, the Nutri Tailor AI health expert in the app, is built for: Nutri365 reads your blood results photographed or uploaded as a PDF, interprets them against the same UK thresholds alongside everything else you have shared, checks for interactions and contraindications, stores the result so the retest has something to compare against, and refers you to a GP or a registered nutritional therapist when a question sits outside scope. The 14-day free trial includes all of this. ## Sources 1. (2021). British Society of Gastroenterology guidelines for the management of iron deficiency anaemia in adults. Gut. PMID: 34497146.
