Sarcopenia Screening Sarc-F Calculator
SARC-F is a 5-item self-report screening questionnaire for sarcopenia (age-related loss of muscle strength and function), developed by Malmstrom and Morley in 2013. Each item on strength, walking, rising from a chair, climbing stairs, and falls scores 0-2, for a total of 0-10. A score of 4 or higher is the validated cutoff for a positive screen, meaning follow-up testing is recommended.
Calculate sarcopenia screening sarc-f quickly and accurately. Enter your values and get instant results with this free online calculator.
This tool screens for the possibility of sarcopenia based on self-reported function; it does not diagnose it. A positive screen is a prompt to get grip strength or muscle mass checked by a clinician, not a diagnosis on its own — and a negative screen does not fully rule out low muscle mass.
