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

Can you give some context, or at least tell me what kind of math (algebra, geometry, category theory, ...) this is?

Hi CRGreathouse,

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 drug-related 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.
I am confused on
Code:
* An AST:ALT ratio equal to one (the level of ALT is higher or equal to AST)...
How can AST:ALT ratio equal to one if the level of ALT is higher than AST ?

TIA

B.R.
