HER 2 Testing Service

We perform over 2000 HER2 Immunohistochemistry and 800 FISH tests per year, on breast cancer cases, using FDA approved and validated assays ( Pathway 4B5 antibody from Roche/Ventana and PathVysion dual colour FISH probe from Abbott Molecular (both CE marked)
All testing is performed in accordance with National Guidelines.

We are a national reference centre laboratory for HER2 testing
We participate in national UKNEQAS scheme for HER2 testing
We are actively involved in monitoring and auditing all aspects of the HER2 service to best meet the need of our users.

Contact Details for HER2 service:

For Clinical advice and interpretation please contact one of the above pathologists.
From September 2012: For clinical advice and interpretation please contact Dr J Starczynski on the above telephone number


All samples submitted for HER2 testing must be accompanied by a request form detailing the patient name, DOB, NHS number and laboratory number of the requesting laboratory. A copy of the histology report should also be included.
A representative paraffin wax block should be submitted for testing, which should contain sufficient tumour material for the HER2 status to be determined.
Alternatively, we do accept tissue sections on charged, Menzel Glazer slides.
If slides are to be sent please provide 5 sequential sections, cut at 4μm, on to charged slides, maintaining placement and orientation on the slide. The slides must be labelled with the laboratory number, including any suffix/part number, patient name and the date that the sections were cut. Sections must be dried overnight at 37 degrees C. Do not heat on.
If slides are being sent for HER2 FISH analysis only, please ensure that the original HER2 immunohistochemistry slide is also included.
Please ensure that the spare sections being sent are representative of the IHC slide that is sent.
Referred blocks are returned to the referring laboratory by recorded delivery once the case has been reported.

Limitations of test

Samples should preferably be fixed in 10% neutral buffered formalin for 6 – 48 hrs. Suboptimal fixation, either insufficient or extended, can cause problems when determining HER2 status.
The use of marker dyes, such as eosin and carbol fuchsin, on breast core biopsies should be avoided as this causes auto-fluorescence on FISH samples making them difficult to interpret.
Heavy use of marker dyes on resection specimens may also cause problems in interpretation on FISH samples.

Turnaround Times for HER2 testing

The turnaround time for HER2 immunohistochemistry is 14 days from receipt of the sample.
