Sample labelling

In order for the laboratories to accept a sample for analysis, both the sample and request form must be adequately labelled.

Minimum data sets are described below. There are more stringent requirements for transfusion and blood grouping requests.

In general, inadequately labelled samples will not be processed and a repeat sample and request will be required.

When a sample is deemed to be unrepeatable there will be a discussion with the requesting clinician on an individual basis. Histology samples and request forms wil lbe returned to the sender.
