Hi folks, Please help me to understand what are; 1) AST:ALT ratio equal to one (ALT is higher or equal to AST) ? My understanding is if both are of equal number Ex. AST=20 and ALT=20 then the ratio equal to 1. But how can ALT higher than AST? 2) AST:ALT ratio higher than one (AST is higher than ALT) ? Thanks in advance B.R. satimis

I don't understand anything in your post. Can you give some context, or at least tell me what kind of math (algebra, geometry, category theory, ...) this is?

Thanks for your response. I think this is basic math on ratio. I read a medical article. It says: Code: * An AST:ALT ratio equal to one (the level of ALT is higher or equal to AST), but the levels are very high, suggests acute viral hepatitis or drugrelated hepatitis. * An AST:ALT ratio higher than 2:1 (two times the level of AST to ALT) is very suggestive of alcoholic liver disease. * An AST:ALT ratio higher than one (where the level of AST is higher than the ALT) could also indicate cirrhosis in a person that doesn't have alcoholic hepatitis. Code: * An AST:ALT ratio equal to one (the level of ALT is higher or equal to AST)... TIA B.R. satimis

Got it. It should really read "less than or equal to one".
