Hi - I've now been told that my GGT is 150+ and ALP is 100+ and these have been more or less consistently raised for almost 10 months. All other LFT's are normal. As stated in previous posts, my Ultrasound was clear, have suffered Vit D deficiency. Doc does not seem overly concerned but is speaking with a Liver Doc at local hospital to try and get a diagnosis. I know that these LFT's can go as high as 500-600 so mine don't seem to be too high even though over normal range. Has anyone experienced this, is there any cause for concern? Waiting to hear from docs but will have to wait (again!) for any news as it's now Christmas holiday. Any comments would be appreciated. Thanks.
