i don't know why she tested positive either. zofran is for vomiting and nausea and it is not your culprit. it is very possible it was lab error. maybe the blood got mixed up. it happens even with checks and balances in place. re-test is needed. i even had a ct scan and was given a diagnosis. then later an mri was done. the doctor told me that the two were not of the same brain. mistakes can happen so have your mom re-tested.
will zofran show up as meth on a drug test. my 65 year old mother recently was taken to emergency room and tested. positive for meth. she is on several prescription drugs. she takes iron zofran zantac metformin lasix synthroid diamox inderal actigal prilosec potassium lexapro and ultram. she does not use drugs and we have no idea why she tested positive for meth and opiates.
