What the Diagnostic Tool does

The NHS England Diagnostic Tool is designed to provide an easy method for support teams to get information regarding the configuration of a device where smartcards are used to access NHS Spine Services. The tool has been enhanced to self-diagnose issues that can occur on a day-to-day basis, allowing members of your IT teams to resolve any configurations that the tool detects. 

The tool itself will show a true representation of a device's configuration. Once it has completed its scan of the system, it will then display an output of potential issues alongside resolutions, as well as issues for other internal teams to resolve, such as security and networking problems. 

The log generated by the tool can be saved and shared with the National Service Desk if your local IT teams cannot resolve the issue or if it's a more complex problem requiring involvement from NHS England.

Please note the tool may not always detect everything, and some configurations may go undetected.


Submit a Diagnostic Tool log

If your IT team cannot resolve an issue you can submit a Diagnostic Tool log by raising a ticket via the NHS England Customer Portal or by emailing it to [email protected]

You can also raise a ticket if you have any issues using the tool itself.
