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. | ||||
