False Positives

False positive test results can be attributed to human error and sample contamination. In addition, there are a number of controlled and uncontrolled substances that will cause a false positive result. Below are some of the many substances to avoid prior to testing. Take this very seriously, your employer or probation officer certainly will. False positives run high with the EMIT, and in some cases this is all it takes to send you to the unemployment office or a parole/probation revocation hearing. National laboratories state that the EMIT test is wrong 25% to 30% of the time, and can result in false positives from legal substances up to 38% of the time!
