HRD and tBRCA tumour testing both analyse tumour tissue and have the same sample requirements - for details please see the test request form for your local GLH. For the successful identification of patients' HRD status it is imperative that the acquisition and handling of tissue samples is carried out to the highest standards. This is essential for the results of HRD testing to successfully influence first line treatment decisions.2

Please refer to the Guide for Optimum Handling and Preparation of Tumour Samples for BRCA Testing for general information regarding the process of sample acquisition and handling.
