Answer: B - The laboratory test which is the best measure of nutritional status is serum transferrin, because it provides information about a variety of nutritional factors and reflects recent changes in nutritional status due to its short half-life. Protein-bound iodine is a measure of thyroid function and is not used to assess overall nutritional status. BMI (body mass index) provides information about body weight related to height, while MCV (mass cell volume) is a measure of red blood cell size; neither BMI nor MCV measures overall nutritional status.
