Description:
Parameter Value Qualifier is a coded value qualifying the analytical results field (PARVAL).
The following list details the most commonly used Parameter Value Qualifier (PARVQ) codes. Note that in general, the PARVQ does not indicate QC failures or deficiencies such as accuracy, precision, blank contamination, or holding time violations. The field EPA_FLAGS exists for the purpose of adding additional CLP data qualifiers, as needed.

Definition
|
ND
|
Analyte was not detected. Enter 0 (zero) for the parameter value (PARVAL).
|
=
|
Represents both the qualitative and quantitative, unqualified, presence of an analyte, at the reported level, above the detection limit.
|
TR
|
Qualifies an analyte present at an estimated concentration above the detection limit and below the reporting limit (RL).
|
>
|
Used in situations where the laboratory reports a quantitative value exceeding the linear range of calibration. The concentration is an estimated value. Exceptions to this rule apply for reporting results of ignitability and flash point. Contact the ERPIMS Help Desk if clarification is needed.
|
CE
|
Estimated or questionable value due to co-elution.
|
S
|
The value reported has been determined by the Method of Standard Addition.
|
TI
|
Tentatively identified compound.
