The Lancet Commission on diagnostics: transforming access to diagnostics (4) Appropriate use of diagnostic tests (3)

2 November, 2021

Dear Massimo and all,

Thank you for your message.

You identifiued three tests that "fetch profit$ to private settings, they are grossly unreliable. A way to derobe 'sick' people of their meagre income", namely:

1) Widal test for typhoid

2) rapid test for helicobacter pylori

3) rapid test for tuberculosis

I would like to invite others to comment.

Are these tests useful? Should they be abandoned or used more selectively?

To what extent are these tests conducted unnecessarily and at what cost to the health system and to individual patients?

Best wishes, Neil
