The Microbiology Department, based at the Norfolk and Norwich University Hospital (NNUH) is part of the Eastern Pathology Alliance (EPA), a managed Pathology network involving laboratories at NNUH, the James Paget University Hospitals (JPUH) NHS Foundation Trust and the Queen Elizabeth Hospital (QEH) Kings Lynn. NNUH is the entity with legal responsibility for the EPA. All Microbiology for the EPA is performed at the NNUH laboratory.
The department is accredited by the United Kingdom Accreditation Service (UKAS) to ISO 15189:2012. The defined schedule of tests for which the laboratory is accredited can be found by clicking on the link below.
To view accreditation schedule no.10296 please visit https://www.ukas.com/
The department has rapid access to national reference laboratory facilities through the UK Health Security Agency.
It also provides epidemiological data for the Communicable Disease Surveillance Centre in Colindale, and investigates outbreaks of infectious disease in support of the Consultant(s) in Communicable Disease Control at the Health Protection Unit.
The EPA Microbiology Department participates in National External Quality Assessment Schemes for bacteriology (including Mycobacteria), virology, serology, mycology and parasitology.
These department pages provide information about how users can access our services, who to contact for advice, which tests we perform, sample requirements, normal ranges and turnaround times. This information is accurate at time of issue and is reviewed and updated regularly to incorporate new developments.

NOTE: All procedures and investigations carried out on a patient need the informed consent
of the patient.
For most routine laboratory procedures, consent can be inferred when the patient presents himself or herself at a laboratory, or other suitable area, within a primary or secondary care setting, with a request form and willingly submits to the usual collecting procedure.
The laboratory infers informed consent has been obtained when samples are received. It is the responsibility of the clinician requesting the test to ensure that informed consent has been obtained.
This consent includes notification to third parties where required by law for example under the Health Protection (Notification) Regulations 2010: we are required to notify
the Health Protection (Notification) Regulations 2010: we are required to notify any infection of public health significance to local public health department as mandated by the regulation. Please ensure your patient is aware of this before submission of samples for testing.
Mon-Fri 09:00 – 17:00
Tel 01603 289847 (Ext: 5847)
Out of hours: First contact the relevant site practitioner.
Some specialised or low volume assays are referred to external laboratories for analysis; these may take up to 4 weeks for a result to become available. Please contact the laboratory if there is any urgency for these investigations. Information regarding specimen type for referred tests can be obtained by contacting the laboratory.
In line with accreditation requirements we endeavour to use accredited laboratories whenever possible. Further information on the reference laboratories we use can be obtained from the Individual Head of Section or from the Quality Manager if required
Authorised results are available on the ICE system for those sites with access, which is updated regularly throughout the day.
Written results are printed and reported every working day including Saturdays. Apart from negative urines, which can be reported after one working day, most bacterial culture results are reported after 2 – 5 days depending on the investigation.
Virology/Serology reporting depends on the investigation required, the frequency of testing and the urgency of the request.
Successful diagnostic virology depends upon the correct timing and selection of clinical specimens and their collection and transport to the laboratory under appropriate conditions. Often the same clinical syndrome can be produced by a variety of viral agents and clinical differentiation of the specific infecting virus may be difficult if not impossible. Generally viruses are shed for only a few days before and after the onset of symptoms and therefore specimens for viral detection should be taken as early as possible in the illness.
Many viral infections are asymptomatic and some viruses may be excreted intermittently from various sites for prolonged periods of time. When a viral infection is diagnosed, either by virus detection or serologically, its significance and relevance to the illness under investigation can be determined only by careful consideration of the clinical picture.
If in doubt please contact the Duty Virologist during normal working hours or the on-call Consultant Virologist out of hours, if urgent.
Significant results are telephoned where clinically indicated.
Many tests can be processed urgently if clinically indicated, and after discussion with Duty Virologist.
Results of urgent requests if ICE access or electronic delivery is not available and unexpected results, which may aid the immediate patient management, will be telephoned. This includes all positive blood cultures and CSFs.
In the event that the laboratory is unable to deliver the required service, e.g. due to equipment failure we will endeavour to contact all relevant users.
Due to IG compliance requirements, results cannot be communicated directly to patients.

The lab operates outside the core hours but is routinely staffed and most responsive during the following times.
During these times the Department’s telephones are fully manned and we will be able to respond to most requests.
Special or unusual tests may have to be analysed in batches and may not be available outside the laboratory’s core hours.
Outside the core working hours the on-call consultant can be reached via the hospital switchboard.
Specimens will be processed outside normal laboratory hours if requested and agreed criteria are satisfied. For more information click here.
Outside of the operational hours the examination of urgent specimens is undertaken by a team drawn from the most experienced Biomedical Scientists (BMS) in the department. A Medical Microbiologist and Consultant Virologist provide clinical cover at all times.
Specimens are accepted by arrangement with the on-call BMS who is reached via the NNUH switchboard for NNUH / Norwich GP specimens, and via the local Blood Sciences Laboratory for JPUH and QEH samples (see Packaging and Transport of Samples). With few exceptions specimens should be obtained before telephoning the BMS.
The specimen and request forms must be labelled clearly as URGENT and need a doctor’s name and bleep number to facilitate communication of initial results. Some requests however are only accepted after consultation with the on-call Medical Microbiologist/Virologist as appropriate and these are marked in the guide. Inappropriate requests will be deferred to the following morning.
There is no facility for patients or other individuals to drop off mail or specimens at the laboratory location – please use Pathology on Level 1 East Block on the main NNUH site.
Phlebotomy, level 3 for blood tests.
