Similarly one may ask, what are analytical errors?

The two major causes of analytical errors are instrument malfunction and operator error. Some examples of analytical errors include equipment malfunction, procedures (i.e., standard operating procedures and assay instructions) not followed, undetected failure of quality control, sample mixups, and test interference.

Similarly, how are pre analytical errors prevented in the laboratory? “Other measures for avoiding preanalytical errors that have proven successful are: never accept an unlabelled sample. Never allow unlabelled or mislabeled samples to be relabeled, if recollection is feasible." "Document relabeling must be approved by an attending physician, with results footnoted.
