laboratory error

laboratory error

any error made by the personnel in a clinical laboratory in performing a test, interpreting data, or reporting or recording the results. Laboratory error must always be considered a possible explanation for findings that are at variance with the composite clinical condition of the patient or are widely divergent from previous laboratory tests. The general procedure is to repeat the test when an abnormal result is found.
