What does "NAD" stand for in medical terminology?

In medical terminology, "NAD" stands for "Nothing Abnormal Detected." This phrase is commonly used in clinical assessments and examinations to indicate that upon evaluation, the practitioner observed no signs of disease, deformity, or any pathological condition in the patient being assessed. It's often employed to reassure both the healthcare provider and the patient that the findings from a physical examination or diagnostic test are within normal limits.

The other options provided do not accurately reflect the common usage of "NAD" in a medical context. "Normal anatomical development" pertains to physical growth and development rather than findings on examination, "Neurotic anxiety disorder" specifies a mental health condition and is not related to a general assessment finding, and "Natural abnormality determination" is not a recognized phrase in standard medical terminology.
