Non-laboratory containers

(Aotea News, March 2009)

The laboratory frequently receives specimens which we consider unsafe to handle or likely to give inaccurate results. Wherever possible we try our best to rescue the specimen but sometimes we are unable to do this. We understand the frustration this causes you when we request another specimen but please understand our own difficulties.

The photographs of a selection of “compromised specimens” received by our Microbiology laboratory during the last month illustrate the range of containers used to deliver specimens to us. None of these were processed because they either posed a hazard to the handler (particularly spilled samples) or were grossly contaminated by material contained within the receptacle. The differing size of containers further causes difficulties with automated processing.

Poorly fitting lids are a major problem and the leaking of fluids can often contaminate an entire batch of specimens being couriered to the laboratory. Occasionally sharp objects are hidden within the sample leading to skin punctures with all the consequences you are aware of.

We understand that the choice of receptacle used by patients is often beyond your control but we would greatly appreciate your help by ensuring that appropriate laboratory-issued containers are utilised.

From April 2009 Aotea Pathology will no longer accept specimens which are in a non-laboratory container unless a specimen is unable to be recollected easily.
