Testing evidence and product reviews

Review the product. Keep the sample visible.

Our listing follows the exact product, formula or configuration. Its evidence record preserves the tested sample, batch, date and scope. We cannot control the stock held by a brand or retailer, and do not promise that a purchase will deliver a tested batch.

A QR code, lot lookup or testing portal helps locate evidence. It is not the evidence itself. We inspect the underlying record and explain what it covers.

What we look for

We match actual third-party evidence to the product, sample or exact certification. We record the source, laboratory or certifier, dates and scope. For numerical results, we preserve the reported methods, units and limits; missing limits are disclosed rather than treated as zero. Brand statements without underlying evidence do not qualify.

The review must explain why the evidence remains relevant to the current formula, source and production process. An older report can remain useful historical evidence without earning a current second tick. A recent page edit or a future best-before date does not refresh the laboratory work.

Matching the tested product to the listing is required. Matching the seller’s next delivery to a tested lot is not required. Receiving a report, an organic certificate or a brand’s testing claim does not by itself complete this review.

Non-detect is not literal zero

A non-detect is interpreted against the stated analytical reporting limit. Without that limit, we cannot infer a numerical ceiling. We also keep raw-material, finished-product and prepared-product samples distinct. A result for one stage does not automatically describe another.

Partial evidence stays visible

A valid result for one substance can be useful even when the complete panel remains unverified. We describe what was reviewed and what is missing. Known detections retain their values, units, dates and sample context; we do not hide a measured result behind the words testing evidence incomplete.

Scope and independence

Historical or periodic reports have different limits from a report tied to a current retail lot. We state those limits beside the claim. Unless expressly stated otherwise, Label And Batch reviews evidence supplied or published by manufacturers and laboratories; we did not collect the sample or perform the analysis.

A manufacturer-funded report can still come from an independent laboratory. We record who produced the report and what is known about the sample source. A testing portal or certificate directory is an access route; we still review the underlying record.

When a report raises a concern

We check the original report, the exact product, the sample and the stated result before changing a claim. A headline or testing summary may point to useful evidence without providing enough detail for a decision. We keep reported concerns separate from results we have verified, and explain any limits or restrictions that follow from the review.

Read the dates separately

A report’s sample and issue dates tell you when the laboratory work happened. A portal update, a page edit and a best-before date mean different things. When a lookup links an older report, we keep the original laboratory date visible and check how the report connects to the product being sold.

Check what the number describes

Read the sample description beside the result. A green bean, a roasted coffee and a prepared drink are different samples. A crop composite combines material from a stated sampling plan; it is not automatically the result for one retail bag. A concentrate diluted into water must retain the amount added and the water volume.

A concentration such as parts per billion cannot be compared directly with a daily exposure amount. Any conversion needs an explicit quantity used, units and preparation basis; missing inputs remain unresolved.

Checking your own batch is an optional extra

If you want to see whether a report covers the package you received, compare its product name, flavor, lot code and any recorded expiry with the original evidence. Use the brand’s lookup where available. A matching code helps establish traceability; it does not expand the tests performed or prove that every unit was tested. Always follow the date and storage instructions on your package.

What a threshold comparison can tell you

A numerical comparison describes the reported sample against a named criterion. Proposition 65 safe-harbor levels concern exposure and warning requirements; they are not a blanket certification that a product is safe. We do not describe a laboratory concentration alone as “Prop 65 compliant”.

• Keep the chemical form, exposure route, units, quantity used and source of the criterion explicit.
• A result below a reference value does not establish that every batch or every use is covered.
• Incomplete or ambiguous evidence cannot earn a testing upgrade. AI can help organise information; it cannot replace the original report, checked arithmetic and review of the scope.

Different products need different evidence

All reviews retain product identity, sample stage and the actual testing scope. Evidence requirements depend on the category; we do not impose a universal requirement to identify the batch that will be shipped.

• For baby food, supplements and protein powders, retain batch identifiers where provided and scrutinise the relevant contaminant panel, sample selection and recency. We need a documented reason that the evidence supports the product review; an old isolated report cannot establish future results.
• For other foods and personal-care products, relevant product reports or a documented testing programme may support the review. Raw ingredients, finished products and prepared servings remain distinct samples.
• For durable goods, match the model, materials, replacement components and operating configuration. Check the exact scope and validity of any performance certification.

Checking the laboratory

For new contaminant-report decisions, our intake check looks for ISO/IEC 17025 accreditation and the relevant scope in the accreditation body’s directory. We check the laboratory location, certificate, validity when the work was done and coverage of the testing activity. A logo on its own does not establish that coverage.

Accreditation and independence are separate questions. We identify in-house testing as such. Missing accreditation or method scope remains a review gap; an alternative quality scheme needs a documented assessment before use. Performance certificates are checked through their own certification scheme.

Three kinds of supporting evidence

We describe the kind of evidence reviewed and the specific tests or performance records it covers, rather than treating all testing claims as equivalent.

• Original independent laboratory reports: matched to the named product or sample; the publisher may be a brand or another party.
• Independently controlled laboratory product analyses: exact-product data hosted by the laboratory, labelled separately from raw certificates.
• Independently verified exact-product certifications: checked with the issuer and limited to that programme’s scope.

These descriptions do not add another approval tier. They show what supports the Testing provided label for the named scope. A brand’s assertion that it tests every batch remains an attributed claim until the supporting programme evidence has been reviewed.

A specification is not a test result

A specification describes a target; a laboratory report records measurements. A certification answers only the questions within its scheme. Ingredient, material or sourcing credentials do not automatically establish contaminant or performance testing. Results remain tied to the named samples even when the listing is for the product.

What qualifies for the second tick

The second tick means we have reviewed actual third-party evidence for this exact product or documented sample. It is not a promise that every possible contaminant was tested or that every future batch will have the same results.

• An original report issued by an independent laboratory, matched to the named product or sample. A brand may publish or supply it; we label that route because the brand chooses which reports to share.
• An independently controlled laboratory product analysis with matching product identity, source dates and disclosed limits. A lab-hosted analysis is labelled separately from an original certificate.
• An exact-product certification checked with its independent issuer, such as NSF, GFCO or an independent sports register. Its tick covers that programme’s scope only. Gluten certification is not a heavy-metals or pesticide test.
• A brand or supplier testing statement without underlying evidence does not qualify. Neither does an unsupported manufacturer certificate or a facility-only certification.

We show only products with ingredient approval and qualifying third-party evidence in the public selection. Incomplete products stay in reserve. Report dates, analysis dates, certification checks and our review dates are labelled separately. ND means not detected at the stated limit, not zero.
