What is a False Positive Urine Test?
If you have taken a urine test that has tested positive for a particular substance(s) that you have not come in contact with via ingestion, inhalation or injection, the result is considered a false positive, in reference to toxicology. Whether drug testing is required for an employer, school or any other reason, there are a few common causes of false positive urine results and some may be avoidable. However, these findings are not limited to drugs. Screenings for certain enzymes, bacteria and other substances pertinent for diagnostic purposes may also render a false result.
