The DQM Check for Estimated Results checks for sample results between the method detection limit and the reporting limit or the quantitation limit.

 

Check

Check name is EarthSoft.DQM.EstimatedResults = Estimated Results.

 

Parameters

This check uses the reportable_result and test_batch_type parameters from Global Parameters.

There are three other parameters:

1.estimated_detection_limit    

a.defaults to "reporting_detection_limit"

b.can be changed to "quantitation limit"

2.sample_type_code

a.defaults to "N"

3.result_type_code

a.defaults to "TRG"
 

Rules

 
There are two rules and they are:

1.MDL=<RESULT<RL (INORGANIC)

2.MDL=<RESULT<RL (ORGANIC)

 

Exceptions

 

Qualify a result IF:

•DETECT_FLAG = 'Y' and

•If estimated_detection_limit = "reporting_detection_limit" then

oMETHOD_DETECTION_LIMIT <= RESULT_NUMERIC <REPORTING_DETECTION_LIMIT

•Else if estimated_detection_limit = "quantitation_limit" then

oMETHOD_DETECTION_LIMIT <= RESULT_NUMERIC < QUANTITATION_LIMIT

•Match each qualified result’s CAS_RN to RT_ANALYTE.CAS_RN

oFor results with RT_ANALYTE.ORGANIC_YN = ‘N’, use Rule #1

oFor results with RT_ANALYTE.ORGANIC_YN <> ‘N’, use Rule #2

 

Errors

 

An error is listed in the Errors tab of the DQM Event Review Form if:

•METHOD_DETECTION_LIMIT, REPORTING_DETECTION_LIMIT, QUANTITATION_LIMIT or RESULT_NUMERIC is NULL

•There is an error when DETECTION_LIMIT_UNIT is converted to RESULT_UNIT

•The QAPP you are using is not using the most up-to-date version

 

Example Error Messages
 

•{FIELDNAME} is NOT Numeric! So, Estimated Result check cannot be completed for Sample, Method, CAS_RN.

•There is an error when detection_limit_unit ({FIELDNAME}) is converted to result_unit ({FIELDNAME}) for {FIELDNAME}! So, Estimated Result check cannot be completed for {FIELDNAME}.

•One of the required rules for this check is not present in the RT_DQM_RULE table. If you receive this error, the check will be skipped. Alternately, the QAPP can be updated following the How to Update Existing QAPPs documentation page.
