Understanding Laboratory Documentation
Laboratory documentation is most useful when it clearly identifies what was tested, how it was tested, and which conclusions the measurements support.
Start with the sample
Look for the sample or lot identifier, sample description, collection or receipt date, and report date. An identifier helps link a report to a submitted sample; it does not by itself establish that every item marketed under that identifier was sampled.
Review the method
Methods should identify the analytical technique and, where appropriate, the conditions and reference materials used. A result without its method may be difficult to interpret or reproduce.
Understand the limits
Reported measurements have a scope. A purity result does not automatically establish identity, sterility, stability, net quantity, or suitability for any particular application. Different claims require different supporting evidence.
Verify the source
Check whether the report is complete, whether the issuing laboratory can be identified, and whether the lot and sample information match the item being evaluated.
