Pre-analytical errors account for up to 70 per cent of all mistakes made in laboratory diagnostic processes. These errors may occur during patient preparation, sample collection/labelling, sample transportation, sample preparation, and sample storage.
Pathlab continues to minimise these risks where they can and as a result their largest remaining source of pre-analytical error is with specimen labelling.
The consequences of a labelling error not being detected or resolved can result in avoidable patient harm.
Pathlab want to re-emphasize the importance of correct labelling of the specimens to facilitate optimal processing of patient samples.
All specimens must be labelled with a minimum of three points of identifications:
Information must be written legibly or printed on an appropriately sized label. Please do not use labels that overhang the sides of the collection tubes as a “flag”; overhang the bottom of the tubes; cover part of the lid of the collection tubes or bundle multiple tubes together with one label.
Please refer to these images for do's and don't's.
Incorrect labelling of sample tubes may result in specimens getting stuck in the automated processing systems causing unnecessary delays or issues with processing. Many labelling errors are from patient self-labelled Microbiology specimens, for example faecal, urine and sputum samples. Please ensure the above information is passed on to all patients for any self-collection required.
All sub-standard labelled specimens* (unlabelled; discrepant or poorly identified specimens) will be rejected and re-collection will be required.
Please contact the Pathlab Specimen Services Department if you have any questions: 07 858 0795, ext 6892. Please send any feedback to Laura Yau.
*Excluding irreplaceable/precious specimens e.g. histology samples are managed by a dedicated process to ensure accurate identification.
