Thank you very much for the useful information Sian.
I regret a little delay in answer due to connectivity issue.
This is normal for you. Nothing significant to get worried about.
Yes this is below the normal range (mentioned on your report); but does not signify any abnormality in the liver; simply means that there is nothing wrong with the liver.
There is one special situation; a condition in advanced cirrhosis (where the normal liver cells are damaged and replaced by fibrosis) due to hepatitis B/C or other chronic liver conditions; where the ALT may be normal or below the normal range.
But there is a clear cut history of decades of liver disease previously and high ALT levels in the past in such cases.
If there is no such history in your case, and other liver functions are normal; no symptoms, there is nothing to worry about at all. The normal range of these liver enzymes represents the average levels of the general population. Almost 2-5% of the general population may have lower levels (as their normal).
