A highly sensitive test is best for ruling out disease when the result is negative. Sensitivity measures how well a test identifies people who actually have the disease; a highly sensitive test has few false negatives. So, if the test comes back negative, it's unlikely the person truly has the disease, and you can “rule out” the condition. This is the SnNout idea: high Sensitivity, a Negative result rules OUT disease.

The other phrasing would mix up the concept: a negative result doesn’t reliably rule in disease, and ruling in disease is more about specificity. A positive result ruling in disease is the opposite idea (SpPin).
