The microbiology Laboratory operates an on call service for CSF samples plus pus from deep seated infection, and body fluids such as pleural or ascetic fluids (but excluding urine).   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 outside of normal working hours.


Please DO NOT call the Microbiology BMS for Covid-19 results, they are not on site and do not have access to results out of hours. All completed Covid-19 test results will be available on CPD.


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.


**Please do not put CSF samples in the Pneumatic Tube System (PTS/POD)**

Coronavirus - useful information

The latest health information about Coronavirus can be found at

Information and updates about our services can be found on this website here.

As of Wednesday 21 October, after reviewing the guidance for visiting as set out by NHSE, the Trust has taken the difficult decision to suspend visiting to all of our sites, with immediate effect.  We have taken this decision to limit the spread of Covid-19, and to protect vulnerable patients and ensure staff safety.  As soon as it possible to safely relax the visiting restrictions we will do so

From Monday 15 June 2020, visitors and outpatients coming into our hospitals will be asked to wear a face covering at all times, to help us reduce the spread of Covid-19.  A face covering can be as simple as a scarf or bandana that ties behind the head.  It should cover your mouth and nose while allowing you to breathe comfortably.  For more information click here
