Pathology tests directory

Our tests directory below includes information to support you to take and submit blood transfusion, chemical pathology, haematology, immunology, bacteriology, virology and other microbiology tests.

All testing is performed within the trust unless otherwise stated.  If the required test is not listed, please contact the microbiology laboratory for guidance.

Please note: when printed, this information is only valid on the day of printing.

Reference ranges given are for general guidance. Results falling outside the reference range do not necessarily indicate underlying pathology. 

Where a colour is given for the top of a sample tube, this applies only to adult size Vacutainer® tubes. Paediatric size and other manufacturers use different colour coding.
