Ranges for normal are determined lab by lab, so the people sampled for your lab's normal range may be a little different from internet listings for other laboratories. Your lab results should list their normal range next to your 65 reading. Normal for my lab is 35-123.
I looked all this stuff up at one point and found that Alk. phosphatase is a bile duct enzyme, so high levels in the blood indicate a blocked bile duct and probably scarring in that area of the liver.
I don't know my friend... Just wanted to say hi! Long time no see, hope you are doing well!
