3 month surgeon visit later today - lab question

I see my surgeon later today for my 3 month visit.  I only have 38 pounds to reach his goal, 48 to reach mine.  So things are definitely going well.

My labs are good, other than 2 things that stick out at me. 

1) my alk phos is low (36) but my googling didn't show this to be much of an issue.  True or not?

2) I have fasting glucose results for the past 4 years and I am slowly trending up - 75, 75, 82, 83.  Cause for concern?  Or OK because it's below 100? 

Thanks for your help, in advance!
