Specimen acceptance policy
The Molecular Diagnostics Centre operates a Specimen Acceptance
Policy in accordance with the requirements of the Specimen Acceptance
Policy of the Directorate of Laboratory Medicine at
This policy follows national directives from laboratory
associated professional bodies.
It is the responsibility of the requestor to ensure that samples
are correctly labelled and request forms completed to the required

information to allow us to identify unequivocally the patient that
the sample has come from, to ensure that the sample and request

Appropriate contact information is required to ensure that reports

Non-compliance with the sample acceptance policy will result in
requests for investigations being delayed or rejected. Users will

If using your local request form, please include the information

Please state the sample type (peripheral blood, bone marrow
aspirate or tissue source for biopsy samples).
