question: I am a 50 yo F. My blood chemistry test for AHDL resulted in a 74. I am not familiar with this term and am not sure if this is cause for concern. Cholesterol/HDL ratio is 2.45(seems good) LDL is 95. AST is12 and ALT is 27. These numbers are marked as low. I am also not familiar with these terms. Please explain AHDL,AST,ALT and interpret the numbers for me.
