Samples will only be processed out of hours if the on-call Biomedical Scientist (BMS) has been paged via Switchboard
Microbiological investigations should only be requested on-call if the results are likely to influence patient management. This may arise either because initial management will be affected by results available immediately or because the specimen is unrepeatable and fastidious organisms may die if cultures are not inoculated immediately.
The following investigations will normally be accepted without question:
Blood cultures will be processed without the need for telephoning. In cases of doubt, the on-call BMS may refer any request to the on-call Consultant Microbiologist for authorisation.
