Urine Toxicology

 

A toxicology test may check for one specific drug or for up to 30 different drugs at once. Testing is often done on a urine or saliva sample instead of blood, because urine and saliva tests are usually easier to do than blood tests and many drugs show up in either urine or saliva. A toxicology screen is a test used to determine if an individual has been exposed to certain legal or illegal drugs. Toxicology screens are usually ordered to see if a patient has taken drugs that could endanger his or her health. If a patient is suspected of taking illegal drugs, a screen for specific drugs that are commonly abused may be ordered
