Flase Negative Test

Patient

Q: I have been taking Ritalin and Adderall,Mostly Ritalin,for close to 23 years everyday twice a day with no problems. I just switched back to Ritalin because of the shortage of Adderall in the state. Last week I as asked to take Drug Test before I got my next subscription. I had no problem with this. I was called yesterday and she said that I had failed as I had no amphethemines in my system. I was of course pretty shocked. Went I got the result faxed to me I showed to a couple of my older doctors, and they said the test had to be specifically for Ritalin and that it does not usually come back positive for amphetimines. Trying to figure out the truth. Any Ideas?
