Microbiology Out of Hours Test Repertoire:

1.  The microbiology Laboratory operates an on call service for CSF samples plus pus from deep seated infection, and body fluids such as pleural or ascitic fluids (but excluding urine). After midnight only CSF samples will be processed. Any other request for urgent work will require approval from the consultant Microbiologist.

The Microbiology BMS on call MUST be contacted by the Switchboard Operator when ANY specimen requires urgent microbiological analysis out of normal working hours.

It is the responsibility of the doctor initiating the request to ensure that all urgent and important samples are expected by the relevant Laboratory.

Example: For urgent cerebrospinal fluid analysis:

If a CSF sample requires analysis out of normal working hours, the Doctor initiating the request MUST contact the Microbiology BMS on call via the switchboard (Dial 0).  Additionally the Doctor MUST also inform the Clinical Biochemistry BMS via Bleep 934.

2 .  Request for blood cultures out of normal working hours.

Blood cultures should be packaged inside a carrier pod and dispatched to the laboratory by pneumatic tube on the York site only.  On the Scarborough site blood culture bottles at present must not be placed in the pneumatic tube system.

While contagious viruses are active year-round, winter is a prime time for norovirus, colds, influenza (flu), and other respiratory illnesses.


These infections are highly contagious, so we urge people to stay away unless their visit is absolutely essential to help reduce the spread of infection within our hospitals.

Hospitals are full of sick people, many of them frail and elderly, so bringing germs into a hospital is the worst thing you can do.  We have an active programme of infection prevention but we can’t spot visitors who really shouldn’t be here.  Please stay at home if you’re unwell to help aid the wellbeing and recovery of our patients.
