Biochemistry and Immunology

The Biochemistry laboratory provides testing with ISO accreditation to 15189:2022 standards. Click on the link below for a summary of the individual test accreditation status.

To support the interpretation of test results, we have provided a list of key reference ranges for in-house tests.

The list is not exhaustive, so please contact the laboratory if any ranges required are not listed. Remember, reference ranges can also be found on the laboratory reports: electronically or on hard copies.

If needed, one of our Chemical Pathologists will support with interpretation or provide advice.

If additional tests are required on a sample that we have already received, please contact the laboratory at the earliest opportunity. We store samples for up to 7 days but whether we are able to perform additional tests will depend on analyte stability.

This important information enables us to interpret the significance of results and ensure that we provide you with the appropriate interpretive comments and age and/or sex-related reference ranges.

Specimens may not be suitable for testing if they are inadequately labelled or if they have leaked or been contaminated. In these circumstances every effort will be made to inform the requesting clinician before discarding the specimen. For ‘precious’ samples, such as CSF, analysis will be carried out at the discretion of the laboratory manager and the report annotated with a comment.

We will process your request urgently when you indicate that this is appropriate.

Please advise us to expect an urgent sample by telephoning the laboratory. Please send urgent samples in a red bag.

Advisory activities

The department consultants are contributing members of the medical staff and ensure the provision of clinical advice with respect to the choice of examinations, use of the service and interpretation of examination results and are responsible for monitoring work performed in the laboratory to determine that clinically relevant information is being generated.

Clinical advice and interpretive comments are only provided directly by, or released with the authority of, consultant pathologists.

The discipline-specific pathology consultants may advise users on, but not limited to, the below:

• the choice, use and interpretation of the examinations and services provided
• advising on individual clinical cases
• interpretation of examination results
• consulting on scientific and logistic matters

We will call you when we come across critically abnormal or unexpected results, so please make sure we have your correct contact information on the request form.
