A sign in medical assessment is defined as an objective finding that can be directly observed or measured by a healthcare provider during an examination. This includes physical observations such as a rash, swelling, abnormal heart rate, or elevated blood pressure. By being measurable, signs provide a reliable basis for diagnosis and treatment within the medical community.

In contrast, the other options relate to different aspects of patient assessment. The first option describes a symptom, which is subjective information reported by the patient, such as pain or fatigue. The third option also pertains to symptoms and personal experiences of discomfort rather than signs. The fourth option suggests that signs must always be confirmed through lab tests, which is not accurate as many signs can be visible during a physical examination without necessitating lab confirmation. Hence, the defining characteristic of a sign is its objective nature, making it a critical part of the medical assessment process.
