Reliability of the total lymphocyte count as a parameter of nutrition.
To evaluate the total lymphocyte count as a means of nutritional assessment, body composition studies (a proven method of nutritional assessment) and total lymphocyte determinations were performed simultaneously in 153 patients. The total lymphocyte count correlated poorly with both the body cell mass and the nutritional state measured by the Nae to Ke ratio. For diagnosing malnutrition, the total lymphocyte count had a false-positive rate of 34% and a false-negative rate of 50%. In a group of 78 patients who received total parenteral nutrition for 2 weeks, the total lymphocyte count did not accurately reflect the nutritional changes. Due to its poor sensitivity and specificity, the total lymphocyte count is of no value as a measure of the nutritional state.
