Which technique is NOT primary to osteopathic structural examination?

The correct answer is the choice involving surveying blood tests because this technique does not directly relate to the primary methods typically employed in osteopathic structural examination. In the context of osteopathic practice, the primary techniques involve hands-on assessments that help evaluate the musculoskeletal system for structural and functional abnormalities.

Observation, palpation, and range of motion testing are fundamental to osteopathic examinations. Observation allows the practitioner to assess the patient's posture, gait, and body mechanics visually. Palpation is a tactile examination that provides information about tissue texture, tenderness, and structural alignment. Range of motion testing evaluates the functional movement capabilities of joints and muscles, which is crucial in identifying restrictions or abnormalities.

In contrast, surveying blood tests is more aligned with laboratory diagnostics and is not a core aspect of the physical examination focused on structural issues in osteopathy. While blood tests can provide useful information regarding a patient's overall health, they do not specifically assess the musculoskeletal system directly. Therefore, the approach of surveying blood tests is not considered a primary technique in the context of osteopathic structural examination.
