Microbiology

Our microbiology laboratory is situated at Worcestershire Royal Hospital.

It provides a diagnostic service for bacteriology and virology as well as maintaining links with outside bodies such as Public Health England, involved in monitoring patterns of infection in the community. 

A proportion of the routine serological analytical processing is undertaken by the clinical biochemistry department; however responsibility for reporting and quality assurance remains with the microbiology service.

Clinical advice and interpretation of results

For clinical microbiology advice

 

  • Out of hours - URGENT ADVICE ONLY - ask switchboard to contact the On-call Consultant Microbiologist

  


On-call (out of hours emergencies)

A countywide emergency on-call service operates out of hours. 

This service is available for:

  • Cerebrospinal fluid (CSF)
  • Joint aspirate, ascitic fluid and aspirates from deep abscesses
  • Specimens collected in operating theatres from body sites otherwise inaccessible, eg peritoneal or liver abscesses.
  • Paediatric urine
  • HIV requests for high risk mothers in labour (by arrangement with duty Consultant Microbiologist)

 

Specimens other than those identified above will not be examined unless by prior agreement with the duty Consultant Microbiologist via switchboard.
 


Acceptance and Rejection Criteria of Pathology Samples 

1.     Minimum Acceptable Patient Identification Criteria for Samples and Request Forms

Stringent procedures, informed by guidance from professional bodies, for the receipt of samples and request forms exist to ensure the safety of the patient (to ensure that the right investigation(s) is performed on the right sample(s) and the results assigned to the correct patient).

The responsibility for requesting a laboratory service/test lies with an authorised practitioner (normally a clinician). It is the responsibility of the requester to ensure that samples are correctly labelled and request forms completed to the agreed standard. Before accepting a clinical specimen, laboratory staff competent in this task must ensure certain minimum criteria for sample identification are met.

To ensure the unequivocal identification of patient and sample certain information is required on all request forms and samples. Sample and request form information mustbe compatible:

 

Minimum Acceptable Identification Criteria Table

ESSENTIAL

DESIRABLE

REQUEST FORM

1. Patients full name or unique coded identifier

2. Date of birth

3. Sex

4. NHS number**

5. Patient’s location or destination for report

6. Patients Consultant, GP or name of requesting Practitioner

7. Investigation(s) required

1. Practitioner’s contact number (bleep/extension).

2. *Date and time sample collected.

3. Patient’s address including

postcode

4. Clinical information including relevant medication.

SAMPLE

N.B. Blood Transfusion requests MUST

have the patient information handwritten on tubes; printed patient labels are NOT acceptable.

1. Patients full name or unique coded Identifier.

2. Date of birth (essential for blood transfusion specimens).

3. NHS number (preferable) or hospital number or unique coded identifier.

1. *Date and time collected

2. Nature of sample, including qualifying details, e.g. left, distal, etc. especially if more than one sample per request submitted.

 

** Note : For patients who have been allocated a unique coded identifier for confidentially purposes (e.g. Sexual Health Clinic patients), the NHS number should not be quoted.

 

It is preferable for information on all samples to be handwritten for the following reasons:

· To reduce the risk of the wrong label being attached.

· Printed patient labels on blood tubes obscure the sample contents and may have to be removed prior to serum separation.

· Printed labels can cause issues with instrumentation used to analyse these samples.

 

Microscope slides must have the patient’s forename, surname and date of birth written in pencil.

Major Incidents – In the event of a major incident the 10 digit Majax number MUST be used in place of an NHS number.

Samples or request forms received without the minimum essential identification criteria stated in this policy may not be processed. Samples received without a request form may also be rejected.

The action taken subsequently may reflect the purpose for which the specimen was intended but might include:-

· Processing the sample and withholding results.

· Sealing the sample and storing it.

· Requesting a fresh sample and request form.

In cases where an inadequately labelled request form/sample is received from a patient who is not easily accessible for a repeat, then, at the discretion of senior laboratory staff, the sample may be processed and the report will show a clear disclaimer detailing the shortcomings of the sample and/or request. The disclaimer will alert the requesting practitioner to take responsibility for the results and for any action taken as a result of the report.

 

2.    Further Acceptance and Rejection Criteria

The quality of laboratory test results depends on the proper collection and handling of the specimen. Correct patient preparation, specimen collection, packaging and transportation are essential factors in obtaining timely and valid test results.

 

Particular note should be taken of:

· The need for prior notification of request to laboratory.

·  Specimen integrity; e.g. special transport (including urgent transportation) and packaging requirements.

·  Sample size requirements. When only a small amount of sample is obtained, indicate which test(s) are clinically most important.

·  Use of preservatives/transport media.

·  Time critical specimens (e.g. antibiotic assay, U & E, cortisol).

·  Correct tubes/appropriate containers i.e. ONLY those provided/approved by laboratory (refer to Pathology Website).

·  Correct sample(s) for request/test(s).

·   “Order of Draw” chart for BD Vacutainer System to avoid sample contamination.

·   Correct mixing of the sample post collection

·  Delivery to correct laboratory in a timely fashion.

 

Samples should be sent to the laboratory with minimal delay. Samples received following an excessive period of time may be rejected.

Specimens sent in an unsafe manner that pose handling and health hazards may be rejected.

Specimens received that are not appropriate for the investigation requested will be rejected.

Requests for inappropriate investigations will be rejected (e.g. Hepatitis C virus quantification without prior positive diagnostic serology).

Request forms received without a sample will be rejected.

 

Requester will be notified verbally or via the reporting process in accordance with local procedures.



Request forms

Please use ICE electronic ordering for all microbiology requests. If ICE is not available use microbiology/virology/antibiotic assay request forms.  For further information on how to use ICE electronic ordering please visit http://nww.worcsacute.nhs.uk/departments-a-to-z/acute-ict/it-training/ice-order-communications/.

Private patients or category 2 requests should be indicated on the request form.

Virology blood test add-ons

Add-ons for routine tests e.g. measles and varicella that are requested within 28 days of the receipt of a gold-top blood in virology may be tested.  Antenatal samples are stored for 2 years so add-ons may be requested for these samples within this time frame. However, due to the variety of tests that can be requested, time dependency of the tests, the different tube types and storage demands, not all tests can be done as an add on. If the requester is unsure as to whether the test can be added on to an existing blood sample, please ring the virology laboratory directly and speak to a biomedical scientist who would be able to advise as to whether the add on can be done.

If a HIV add on is requested, a request form needs to be received in the laboratory before testing.

PHE guidelines for issuing varicella-zoster immunoglobulin (VZIG)

Guidance on use of Varicella Zoster Immunoglobulin (VZIG) during supply shortage

 

Clinical information

Please provide relevant clinical information on the request form.

For example:

  • Diagnosis, what antibiotics the patient was on prior to taking the specimen or what antibiotics are to be started
  • Date of onset and clinical symptoms are particularly important for serological samples so that the appropriate tests can be performed
  • History of foreign travel for investigation of enteric pathogens
  • Wound swabs - state site of wound as this will determine significance of any organisms isolated
