No. No drug test of this type is 100% accurate. There are several factors that can make the test results negative even though the person is abusing drugs. First, you may have tested for the wrong drugs.

Can a lab detect a false positive?

False-Positive Results. In some cases, a drug test may report the presence of illicit drugs, although none were taken. While this is not common, no test is 100% accurate. Lab errors account for some of the mistakes, but most false-positives may be attributed to over-the-counter drugs and foods that can affect the test.

What does cutoff mean in a drug test?

Cut-off Levels One of the key concepts within drug testing is the application of a cut-off level. This is the point which segregates a test result as being either positive or negative. For drug screening tests, a cut-off is chosen that will optimise drug detection but minimise the number of false positive results.
