Hello. My creatinine and SGPT(ALT) levels are below the normal values. I consulted two doctors about this and they both said that I am perfectly fine and healthy. However, they did not explain fully well the cause(s) of these below normal values. According to my internet reasearches, they may be related to a liver problem but they said that my liver is very much healthy. I am happy to hear it but my question was not answered -- why is it that they are below the normal range? Any idea on this? and what could be the implication of these below normal values level to my application?
