The doctor said the normal ALT/SGPT range is 30-57. I had an ALT measuring of of 90 in January. In May it was down to 66 after I lost weight. I began weight lifting. I have abstained from alcohol and acetametaphine this whole time. All my other bloodwork is OK. I do take multivitamen supplements and recently had been taking advil for some backpain. Should I be overly concerned. Can I drink alcohol?
