No, as I explained, when disease prevalence is low, most tests -- even when clearly &quot;positive&quot; -- don&#x27;t shift probabilities in any appreciable way, and just add to the noise, and render decision making even harder.<p>Of all patients, nurses and doctors are the ones who are the less likely to asks for &quot;more tests&quot;, precisely because they understand that they are essentially meaningless when pre-test probability is very low.<p>Suggested readings :<p>1.
