Non-invasive

Definition

Non-invasive refers to techniques or procedures that do not require the introduction of instruments or devices into the body, allowing for observation and analysis without causing physical harm. This approach is crucial in various medical and diagnostic applications, as it minimizes discomfort and risk to patients while enabling the collection of vital physiological data.

5 Must Know Facts For Your Next Test
