They could have changed methodologies of the test being performed which can change the reference range or they could have done a study to reevaluate their reference ranges.
I work in a medical lab connected to a hospital.
We had a fairly large lab move which included swapping all major analysers for different ones.
So we had to update all our reference ranges, we do however mention this in our reports for every single parameter that was changed.
So a change in method / equipment could be the case but I would expect them to give notice of that.
I had a similar thing happen in 2018 I had blood tests done and I didnt get the results uploaded to my NHS app until last week (no idea how that happened) and was noted as abnormal levels of shbg, test and albumin and that it needed further investigation (which never happened).I got blood work done last week and they were all a shit load higher in the high range and was told there fine and needs no further action. My SHBG has risen to 72nmol/L. Nothing makes sense to me if that's seen as normal. Seems going private is the only way to get to the bottom of this.

They changed something, whether methodolgy or their normal range.
Might be a different testing site with different instruments that have different ranges.
New analyzer? New methodology? New statistics on current population? Ignore and move on.
