SUGGESTED FORMULA (Ref Medscape 2/1/2018 - New Guidelines Provide a Clearer Path Forward for Abnormal Liver Tests. Balistreri.)
R ratio for liver injury
R = (ALT value / ALT ULN (upper limit of normal) / (Alk Phos / Alk Phos ULN)
R ratio > 5 suggests hepatocellular injury, less than 2 cholestatic injury, 2 to 5 a mixed pattern
Agreed. Useful!
