     Quality Control Parameter Frequency Compliance
     The following report summarises the frequency of laboratory QC samples analysed within the analytical lot(s) in which the submitted sample(s) was(were) processed. Actual rate should be greater than or equal to
     the expected rate. A listing of breaches is provided in the Summary of Outliers.
