Overall, choosing a screening procedure is a matter of balance between the healthcare setting, resources, type of patient, operational problems, the characteristics of the tool, etc. Some tools/procedures for assessing nutritional risk were proposed by expert panels [1,2,6,8,9,10] based on the relationships between malnutrition and weight loss, low BMI, decreased food intake, etc. Others include basic laboratory test data, of which the foremost component is albumin concentration, and were developed by examining the nutrition-related predictors of clinical outcomes [2]. The gene discussed is ALB; the disease is nutritional deficiency disease.
