<human>: Hi my ALT and AST levels are quite high. As of Jan 20th 2015 my AST WAS 423 and my ALT was 164. LDH: 935.Last November 2014 I had a AST level of 21 and a ALT of 37. What could be the cause of this drastic change in levels. I did drink some cocktails(capt coke) the night before my appointment, although I did fast 8hours prior to the appointment as told. Heading to the appointment I was running on about 3 hours of sleep and I did take a 5 hour energy drink.From what I remeber in my first initial blood draw I didn t eat or drink and my levels were fine. Can these numbers change that dramatically over one night? I m healthy, about 6 180lbs. Rarely drink, and I seem to think I have a healthy diet. Going in next week for another blood draw and HEP screening. Any ideas what could be wrong and what I can do to possible lower these levels?
