There is a tool to estimate risk ratio described there. Best regards, M. Shulgina

However, poorly trained, staffed, motivATED ETC, laboratory will not be proficient no matter how many tests are done dayly. Number of tests to be done by a laboratory depends on the need of the programme, staff and equipment. In some cases laboratories with low volume ...
