Hello all. I just got my gleevec trough level back from ARUP labs. It is my understanding that they are the only lab in the United States that does the test. You have your blood drawn basically 23 plus hours before you take your next dose.... So I got my trough levels back and they are quite high. The norm for CML patients is thought to be a trough level of 1000. The situation is that if you drop down to 300 mg of Gleevec, the trough drop is probably not linear. So I could drop below the treatment level of 1000. This trough level is not “hard science” but has been bandied about enough to cause ARUP to be running a test for it.
Please tell me if any of you run your trough levels.
