Serology
Blood samples for the presence of viral and bacterial antigens and antibodies (IgG and IgM), to help diagnose diseases and check immune status, are tested within Serology.
Specimen requirements
Samples should be transported to the laboratory as soon as possible. If specimen transport will be delayed, e.g. from primary care, specimens should be stored in a refrigerator until transported to the laboratory.
The analysers are able to process blood samples from a range of blood tubes for each of the tests performed.
Please check on the table below as some tests cannot be performed on blood in certain tubes.

Some serological tests cannot be performed in-house; they are sent by us to other laboratories for testing:
For details of samples needed for molecular testing and viral loads, please see:
If serum for saving only is required, please request short-term storage (three months).
For a more comprehensive list, please refer to the Microbiology Laboratory Users Manual (pdf, 684 KB)
Laboratory turnaround time
There is a turnaround time of three days for most serology testing. The exceptions to this are H. pylori and Hepatitis E virus where the turnaround time is seven days.
Some tests may take longer if they need to go to a reference laboratory for confirmation of a result.
Laboratory method
Samples are run on immunoanalysers in the core automated laboratory and in the Serology section.
Where to find results of these tests
- All results are returned electronically where possible (EPR, SunquestICE).
- Some results may be phoned to clinicians and GPs.
- Results are never given directly to patients by the laboratory staff.
