The FAST™ score calculator is a tool for clinicians to calculate the probability of a patient with suspicion of NAFLD as having active fibrotic-NASH (NASH+NAS ≥4+ F≥2).  The calculator takes into account LSM by VCTE™, CAP™ and AST, and was developed based on a prospective multicenter study. The FAST™ score and calculator are presented as an educational service intended for licensed healthcare professionals. While this score is about specific medical and healthcare issues, it is not a substitute for or replacement of personalized medical advice and is not intended to be used as the sole basis for making individualized medical or health-related decisions.
