I'm incredibly frustrated! I'm in a self-entered out-patient facility. I have no reason to dilute a urinalysis. I was told that I kept having a dilute UA (I am new to this program, but don't want to keep at it if they keep looking at me like I'm guilty when I know I'm not!). They came to this conclusion because my creatine level in my urine was anywhere from 8-15? They said normal is 20+? I don't know medicine, but I do know that I didn't tamper with anything! Could this be a health concern? Are there vitamins that can cause this? I drink about 2 liters of water per day; sometimes less. Please help me figure out why this is happening! Thanks so much, N.
