Which term describes something that can be measured or felt by an examiner?

The term that describes something measurable or observable by an examiner is "sign." Signs are objective evidence of disease or condition that can be detected through observation or physical examination. For instance, a fever, rash, or swollen lymph nodes are signs that indicate a potential health issue.

In contrast, symptoms refer to subjective experiences reported by the patient, such as pain or fatigue, which cannot be directly observed or measured by an examiner. Conditions typically refer to the overall state of health or the presence of a disease but do not specifically indicate measurable attributes. A diagnosis is the conclusion drawn based on the combination of signs and symptoms, but it does not itself represent the observable findings. Therefore, "sign" accurately captures the concept of measurable or observable phenomena in a clinical setting.
