Keep a reported percentage tied to its method and sample

Read the whole result before editing the percentage

Open the genuine report used for the claim and locate the specific result, rather than relying on a filename or a percentage repeated in a supplier message. Record the document identifier, its date and version, the result label, the exact value, its unit and any qualifier printed with it. Preserve an inequality or stated limit as written; do not turn it into an exact measurement.

Record the method label and sample identity from that same report. If the document does not name one of them, mark it unstated and identify the question for the report issuer. Do not fill the gap from another report, a product category or what the team expected the method to be.

This review goes beyond checking that the product page links to a report. A working link tells the reader where the file is. The present question is whether the percentage on the page retains the meaning and scope expressed in that file.

Compare the claim's label and reach with the report

Read the words next to the percentage on the product page. Does the label match the reported result, or has the page replaced it with a broader term? Keep the report's method-specific terminology unless a qualified interpretation supports a different description. The number alone cannot justify treating differently named measurements as interchangeable.

Trace the sample identifier to the product or batch the page associates with it, using the business's actual records. Keep the distinction visible if a report identifies a particular sample while the page describes current inventory more broadly. A matching product name alone does not establish that the documented sample represents every item now offered.

Check the title, specification table, badge, label image and nearby explanatory text together. A method named only in the linked document may not explain a broad claim presented elsewhere on the page. The editorial task is to make the stated basis and sample context clear where the percentage is presented, without inventing an interpretation that the report does not supply.

Do not use the percentage to infer product content, analytical accuracy, suitability or safety. Those are separate claims requiring their own support. The worksheet records the boundary rather than calculating an answer to those questions.

Neither advertising guidance nor a laboratory standard certifies the claim

The FTC's truth-in-advertising guidance calls for truthful, nonmisleading advertising backed by appropriate substantiation, including on websites. That general principle is a reason to compare the public statement with its evidence. It is not a ruling that a specific phrase is lawful or that a displayed percentage is adequately substantiated.

ISO's public description of ISO/IEC 17025:2017 concerns the competence, impartiality and consistent operation of testing and calibration laboratories. It does not turn a product-page percentage into a product certification. A reference to the standard cannot supply a missing method label, establish which sample was tested or authenticate the merchant's report.

Keep scientific and legal questions with the appropriate qualified reviewer. Ask the report issuer to clarify the specific field or interpretation that is missing; do not ask a copy editor to settle whether two methods measure the same thing. Legal applicability to the actual product and market remains separate from this content comparison.

Choose an editorial action for the specific gap

When the value, label, unit, method and sample connection are documented, preserve that context in the public wording and retain the report reference in the editorial record. Describe the outcome as a traceable statement, not as a scientific validation of the result.

When the number is accurate but the claim's label or product scope has expanded, narrow the wording to what the report and product records support. When the method, sample connection or interpretation remains unresolved, hold or remove the unsupported percentage claim until the missing basis is established. Do not replace the number with a broader quality assurance that has no evidence.

Record the affected URLs and images, the owner of the correction and the wording actually published. A changed product description leaves work open if the original broad percentage claim remains in a badge or gallery image.

For a Prism website-review consultation, identify the research-only storefront, the public claim and the question about its presentation. Agree the pages, requested work, responsibilities, fees and terms before work begins. Use the public form for a summary, not private reports or identity records; the inquiry does not purchase a review or establish processing eligibility.

Percentage evidence record

Use one copy for each public percentage and its supporting report result. Fill the last column from real records. Classify the claim as context preserved, wording broader than evidence, or basis unresolved; none of those labels certifies the measurement.

Worksheet entries are not submitted by Prism’s worksheet and are not saved by the site. Use record types, availability, anonymized observations, or match/mismatch results. Do not enter government identifiers, customer names or addresses, customer messages, receipt-access links, card or bank details, passwords, or keys.
