High SGOT / SGPT ratio & A/G ratio.

I recently got my liver function test and lipid profile done as i will be starting Isotretinoin as prescribed by my dermatologist. For my LFT, everything is well within the biological reference range however the SGOT/SGPT ratio is 1.6; A/G ratio is 2.0 (bio reference range was given as 0.9 - 1.8); Alkaline Phosphatease (ALP) is 43 U/L (bio reference range: 44 - 112 U/L). the individual SGOT (aspartate aminotransferase) & SGPT (alanine aminotransferase) values are 19 U/L and 12U/L respectively (well within the biological reference range). my dermatologist says I can start isotretinoin however I'm a bit worried as when i google the SGOT / SGPT ratio, it shows that i might have liver cirrhosis?? I'm just scared that if I start isotretinoin, i might damage my liver. my lipid profile is also normal only the LDL / HDL cholesterol ratio is slightly below the biological reference range that was given. it was 1.2 (reference range was 1.5 - 3.5). I'm a 23 year old female.
