The results indicate that decreased levels of albumin (<3 g/dL) and hemoglobin (<11 g/dL), along with elevated homocysteine, CRP, IL-6 (>7.5 pg/mL), and IP-10 (>250 pg/mL), should alert medical professionals to potential malnutrition in hospitalized patients. This evidence concerns the gene CRP and nutritional deficiency disease.
