Screening for muscle atrophy is limited by a lack of established diagnostic criteria, although many have been proposed. Diagnostic criteria for other conditions such as sarcopenia or cachexia can be used. These syndromes can also be identified with screening questionnaires. Muscle mass and changes can be quantified on imaging studies such as CT scans or Magnetic resonance imaging (MRI). Biomarkers such as urine urea can be used to roughly estimate muscle loss during circumstances of rapid muscle loss. Other biomarkers are currently under investigation but are not used in clinical practice.
