4.3 Choosing laboratory tests

As noted above, the use of RDTs requires close collaboration between clinicians and microbiologists, and decisions about introducing new tests may be made by a diagnostic stewardship committee. This committee will be aware of the long-term cost savings and patient benefits of using RDTs. Larger facilities may have a clinical microbiologist, who will advise on new tests and oversee their evaluation and introduction.

Diagnostic tests must be appropriate for the individual patient and should target all pathogens that cause acute infections.
