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.
