What tests are used to diagnose marasmus?
Diagnosis primarily relies on body measurements, which are then scored according to different scoring systems for children and adults. Upper arm circumference and height-to-weight ratios help healthcare providers rate the severity of undernutrition. Height-to-age ratios help define growth delays in children. Healthcare providers will usually recognize the type of undernutrition (marasmus) based on physical signs.
The next step will be to take a blood test to identify the secondary effects of marasmus, including specific vitamin, mineral, enzyme and electrolyte deficiencies. This will help determine the child’s or adult’s nutritional needs for refeeding. A complete blood count can also help reveal any infections or diseases that may have contributed to or resulted from marasmus. They may check a stool sample for parasites. Infections will need to be treated separately.
