Overview

There are no specific laboratory tests, group of tests, or indices that are satisfactory for the assessment of protein energy malnutrition. However, laboratory findings consistent with the diagnosis of protein-energy malnutrition include abnormally low blood glucose, hypoalbuminemia (10-25 g/L), hypoproteinemia (transferrin, essential amino acids, lipoprotein) and hypoglycemia.

Laboratory Findings

Laboratory findings consistent with the diagnosis of protein-energy malnutrition include:[1]

Specific laboratory findings in patients with kwashiorkor include:

Specific laboratory findings in patients with marasmus include:
