Ignacio de Ulibarri et al developed a simple screen for nutritional status called the CONUT (CONtrolling NUTritional status). This can help to identify a patient who may benefit from a closer evaluation. The authors are from Hospital Universitario de la Princesa in Madrid, Spain.
Parameter:
(1) serum albumin in g/dL
(2) total lymphocyte count per µL
