The screening tests used in employment and schools are more likely to return a false positive than the more precise tests where a lab collects and tests urine samples, according to CVS.com. Urine tests are often preferred as they are less invasive than other types of testing.

A false positive may prevent an applicant from getting a job or a student from playing a sport. The applicant has a better chance of protecting his rights if he knows he has taken legal substances that sometimes cause a false positive.

Positive tests may indicate a mother using marijuana while pregnant and, along with other indicators, may precipitate a call to child protective services. Research comparing the way the nursing staff collected the urine samples indicates the chemicals in several brands of baby soaps cause false positives.Learn more about Health
