Is it possible that i am farther a long then my doc and the ultrasound says i am?

Possible: It is possible that your ultrasound looks okay and your lab of the kidneys gives a certain value, but your kidneys are actually slower than what the lab shows. Although this is possible, it is not likely, since your doc factors these possibilities when he is talking to you. It is important to see a kidney specialist though to sort that out if your kidneys are weak (as i glean through your message).
