The national genomic test directory specifies which genomic tests are commissioned by the NHS in England and the patients who are eligible to access to each test. The directory is regularly updated and clinicians should check the current version of the directory before referring patients.

Updates to the directory are made once they are approved by the NHS and are summarised below. From the time of the update, it can take up to three months for significant changes and new tests to become fully available. This is due to the time it can take to develop, implement and verify new testing procedures.
