De Jong et al developed a nutritional index based on clinical and laboratory data to evaluate an adult patient for malnutrition. The authors are from the University of Limburg in Maastricht, The Netherlands.
Parameters:
(1) serum albumin in g/L
(2) serum prealbumin in g/L
(3) total lymphocyte count in 10^9/L
(4) percent of ideal weight
nutritional index (NI) =
= (-0.24 * (serum albumin)) – (19.21 * (serum prealbumin)) – (1.86 * (total lymphocyte count)) – (0.04 * (percent ideal weight)) + 20.68
where:
• The percent ideal weight = (actual body weight) / (ideal body weight) * 100
• The ideal body weight is based on the Metropolitan Life Insurance Company tables.
Interpretation:
• An index > 0 indicates that the patient is malnourished.
• An index <= 0 indicated that the patient is not malnourished.
