LABDL (Laboratory Detection Limit)
Attributes | Format | Tables | Guidelines & Restrictions | Definition |
---|---|---|---|---|
N9 | Number | RESULTS | LABDL may not be left blank except for UNITS = PERCENT or TIC parameters (PARVQ = TI). | The Laboratory-Established Method Detection Limit (i.e., the minimum detectable concentration of an analyte that can be measured and reported with 99% confidence that the analyte concentration is different from a blank for a given matrix). |
LABDL must be greater than zero except for UNITS = PERCENT or TIC parameters (PARVQ = TI). | ||||
LABDL must be adjusted for dilution. | ||||
Special Notes | ||||
LABDL may contain the same value as the REPDL field, depending on the reporting format of the individual laboratory. When LABDL = REPDL, the REPDLVQ should be entered as MDL. |
