Physical Exam and Observation. Subjective Global Assessment • Assesses nutritional status based on features of the hx and physical examination. • Can easily be taught to clinicians. • Technique is reproducible – Good correlation between subjective and objective measurements. 21

nical , Subjective Global Assessment (SGA) of Nutritional Status Subjective Global Assessment (SGA) is a: status based on features of the history and physical examination a method of rating a patient's nutritional status, with subjective observations being given values on an ordinal scale.
