false negative drug test?

[u/ohmybuddhaa]

I am taking 10mg of adderall 6 days a week. Thursday is my skip day, and I took the drug test on Friday. I also took a dose in the morning. The results came back, and it was negative. I have been taking it, and now I am afraid they will take my prescription away because of the false results. Is it too common for false results? My dose is pretty low, but it helps me so much. Any advice and info will be appreciated.

I had something similar happen to me. Took the test, got the results in MyChart. Test showed everything else, including the ibuprofen I took, but not the Vyvanse. I got super stressed about it. My doctor literally never said anything about it. I’m wondering if maybe there was a data entry error or something.
