Diagnostics Assessment Programme

Content under review

We're updating this page following the publication of our new methods, processes and topic selection manuals. Our previous manuals still apply to evaluations that started before 1 February 2022. The new manuals apply to evaluations that began after this date.

This guidance evaluates new, innovative diagnostic technologies. It includes all types of measurements and tests that are used to evaluate a patient's condition.

Diagnostic technologies may be used for various purposes. These include:

  • ruling in or out a specific disease
  • general examination looking for clues to the cause of the symptoms
  • staging, or additional testing to assess how advanced or severe the disease is
  • monitoring a patient over time to determine changes in their condition
  • screening tests to look for conditions in patients without signs or symptoms of the specific condition.

Get a technology assessed

If you manufacture a diagnostic technology, you can ask us to consider it for guidance. We look at how it compares with technologies already available and if it offers advantages over current practice.

Static list

We regularly review our diagnostics guidance. If there is no new research or evidence available that would have a material effect on the guidance, it gets moved to the static list. If new evidence becomes available, the guidance can be transferred back to the active list for further appraisal.

The following guidance has been transferred to the static list.
