Reporting limit
The laboratory threshold used to report quantified analytical results under a stated method and reporting convention.
Why it matters
Results below the reporting limit may be handled differently by the laboratory. Read qualifiers and units rather than treating every blank or nondetect as a zero concentration.
In practice
A project example
A diluted sample has a higher reporting limit that affects whether the result answers the investigation question.
