We are proud to announce the availability of the TDL TestGuide app for our customers.

Available for iOS and Android phones and tablets, the app extends upon the extensive content available in our new TDL Pathology Handbook.
You will have access to information on more than 1000 pathology topics, reflecting our deep collective knowledge across all areas of pathology – together with information on the wide range of tests available from TDL.

You can easily search for tests and conditions and there are hyperlinks within the text so you can find out about related topics or cited references.

The app will continually evolve so that we are able to update content with new or revised entries on a regular basis. All content is stored on your mobile device, so you can still look up information when you are not connected to the internet.

As a customer of TDL you will need your Source Code, which can be found on the letter enclosed with your copy of the TDL Pathology Handbook. Alternatively contact if you need help with finding your Source Code.

Click on one of the links for the appropriate app store for your device and then download the app. You just need your source code and an email address to complete the sign-up process.
