In some instances it is possible a result is reported as less than the reportable detection limit (RDL), where the RDL is actually above a particular criteria or guideline. This is usually due to some form of interference either from the sample matrix or a target or non-target analyte.
Dilution of the sample matrix is the primary approach to combat or decrease the impact of interferences and the typical cause for raised RDLs. Dilution directly affects the RDL or detection limit by the same magnitude. The dilution itself can ensure instrument functionality and confidence in the reported data.
There are some scenarios where there is actually no method developed that can meet the required criteria.
