Doh! Well I know it was bound to happen at one point or another! I calculated Luke's phe on the fly and got it a touch wrong, darn it! Saturday when I tallied up his final numbers in the evening I realized I had gone about 20 mg of phe over his limit. At first I was super upset and mad at myself but I calmed down and told myself that it's done & I cannot change it now. Really with his low levels last week this should not make a difference. It is less then 4% more then his usual amount, so it is not like I doubled it. Well I did the heel poke this morning and tomorrow first thing I will take it into the Lab. I will be very curious (and slightly anxiously) awaiting these results!
