Laboratory reports, translated
A real laboratory report is useful only when the fields are read together. This guide uses an independent public report—not an EssenceCraft product—to show exactly what the language means.
No badges. No vague purity claims. Just the document and how to read it.Start with a real report
The example below transcribes the heavy-metal panel from a public AGQ USA analytical report. The complete three-page report remains the source of record.
| Analyte | Result | LOQ | Technique | Unit |
|---|---|---|---|---|
| Total arsenic | 0.012 | 0.010 | ICP-MS | mg/kg |
| Total cadmium | <0.010 | 0.010 | ICP-MS | mg/kg |
| Total lead | 0.027 | 0.010 | ICP-MS | mg/kg |
| Total mercury | <0.010 | 0.010 | ICP-MS | mg/kg |
The LOQ saga, made simple
They may appear in the same unit, but they answer completely different questions. LOQ describes the laboratory method. An applicable safety or specification limit is set separately for a particular product, market and exposure basis. A result shown as <LOQ means “below the measuring floor”—not “below the approved safety limit.”
The lowest concentration this specific method can reliably quantify as a number.
The maximum allowed concentration must come from the applicable regulation, standard or product specification.
A lower LOQ means a more sensitive measurement. It does not automatically mean a safer product.
That limit must be named and sourced. It cannot be inferred from the LOQ printed on a report.
Use the same units and exposure basis. Never use the LOQ column as the approved maximum.
Think of a ruler. LOQ is the smallest marking the ruler can reliably measure. The safety threshold is the boundary you must not cross. One describes the tool; the other describes the limit.
