All positive Blood cultures, CSFs, other sterile fluids and clinically important isolates are communicated promptly by the Consultant Microbiologist to the relevant clinical team, the ward sister, or the most senior person available who is dealing with the patient. Results from reference laboratories will be telephoned to the requesting wards, as deemed necessary by the consultant microbiologist. Provisional results may be obtained by telephone if available. Final results from all samples are available on Fusion or via GP links.
The reference ranges of the following tests are given below.
- Aspergillus precipitins
- Avian precipitins

The turnaround time (TAT) for specific tests/specimen types is calculated from the date of receipt to the date of authorisation. Targets for each request type are set by the laboratory for the number of calendar days within which 90% of reports are issued. General bacteriology specimens are processed 7 days a week (including follow up work). Serology, parasitology and mycology requests are processed Monday to Friday. The turnaround times achieved for specific requests are shown in the table below.
|Specimen/Request type||TAT*||Specimen/Request type||TAT*|
|Urine Microscopy||0||Hepatitis serology (A,B,C)||3|
|Faeces Culture||3||Toxoplasma serology||3|
|Blood culture||6||Legionella/Pneumo Urine Ag||0|
|Chlamydia/GC (molecular)||3||Chlamydia IF||1|
|GC culture (Sexual Health)||3||HIV viral loads||6|
|CSF culture||2||Most common/vital referred tests|
|TB culture||60||Meningo/Pneumococcal PCR||10|
|Resistant Org. Screen (pre-op)||3||Respiratory PCR||6|
|Antenatal infectious disease screen||0||Aspergillus precipitins||15|
|HCV viral load||14|
