QC Status Codes for Accuracy Assessment

The standard status arising from standard assessment for the result of a blank, standard or spike QC sample scheme analyte (SSA) analysis may be one of:

• Not Tested—Indicates that the sample scheme analyte is not assessed due to it having no result as yet.
• Not Required—Indicates that assessment was not required for the sample scheme analyte. This may be due to the QC not being active for the scheme version analyte, or it was not the correct analytical type of sample. Sample scheme analytes where the scheme version analyte is inactive for QC assessment, or flagged not have their assessments recorded in QC history, are not recorded in QC history and therefore not available for QC history reporting.
• Pass—Indicates that the result for the sample scheme analyte are within acceptable accuracy limits.
• Lower Warning—Indicates that the result for the sample scheme analyte has exceeded the lower warning limit for the accuracy assessment.
• Upper Warning—Indicates that the result for the sample scheme analyte has exceeded the upper warning limit for the accuracy assessment.
• Lower Failure—Indicates that the result for the sample scheme analyte has exceeded the lower failure limit for the accuracy assessment.
• Ignore Lower Failure—Indicates that the result for the sample scheme analyte are below the lower failure limit, and that failure was subsequently ignored by the operator.
• Upper Failure—Indicates that the result for the sample scheme analyte has exceeded the upper failure limit for the accuracy assessment.
• Ignore Upper Failure—Indicates that the result for the sample scheme analyte are above the upper failure limit, and that failure was subsequently ignored by the operator.

The following statuses can only be set by a custom accuracy assessment script:

• Warning—Indicates that the result for the sample scheme analyte has exceeded warning limits for accuracy assessment.
• Ignore Warning—Indicates that the result for the sample scheme analyte are outside warning limits, and that warning was subsequently ignored by the operator.
• Trend Warning—Indicates that the result for the sample scheme analyte has exceeded trend warning limits for the accuracy assessment.
• Ignore Trend Warning—Indicates that the result for the sample scheme analyte were assessed as a trend warning, and that trend warning was subsequently ignored by the operator.
• Failure—Indicates that the result for the sample scheme analyte has exceeded failure limits for accuracy assessment.
• Ignore Failure—Indicates that the result for the sample scheme analyte are outside failure limits, and that failure was subsequently ignored by the operator.
• Trend Failure—Indicates that the result for the sample scheme analyte has exceeded trend failure limits for the accuracy assessment.
• Ignore Trend Failure—Indicates that the result for the sample scheme analyte were assessed as a trend failure, and that trend failure was subsequently ignored by the operator.
