What a laboratory report can tell you

On this page

An analytical report describes a sample and the listed measurements. It is not a universal safety certificate, evidence of therapeutic benefit, or an automatic description of other batches with the same name.

  • First connect the document to a particular sample.
  • Then distinguish a measured result from its assessment criterion.

Which material was tested?

Match the product name, batch identifier, sample description, laboratory and document date. Testing a starting ingredient does not automatically test a finished mixture. A mismatch needs explanation; a logo or tested badge cannot supply the missing connection to a package.

  • One document does not characterize every future shipment of a product.

What was measured?

FDA guidance for US manufacturers distinguishes methods, limits and actual results. This is a useful reading framework, not confirmation of Israeli compliance. For each entry, look for the measurement, unit and comparison criterion. A pass alone can omit useful detail.

  • Testing one measurement does not imply screening for every possible contaminant.

Not detected is not necessarily zero

NIST distinguishes signal detection from quantitative determination. Read ND, LOD and LOQ alongside the laboratory explanation. An undetected signal does not establish absolute absence. Interpretation depends on what was sought, the method and its sensitivity, not a universal promise.

  • An unlisted measurement remains unverified within the supplied document.
Result

What the laboratory reported.

Criterion

What the result was compared against.
