All of these combine together to cause a SCREEN test to read preliminary . At the laboratory, the confirmation test is designed to detect only ONE. The one substance must be present at 15ng/mL in order for the lab to consider the urine positive. If the substance is present at 14ng/mL or lower, the urine will be considered negative. Most employment drug tests in the US are a 5-panel test, meaning they test for the 5 drugs that are required by federal employment laws.
Please check your instructions for more information on the cut-off levels being used in your test. If an immunoassay test detects a drug the presumptive positive specimen may be sent to GC-MS or LC-MS/MS confirmation testing. Many times, these individual compounds are present in concentrations much lower than the total immunoassay response, thus resulting for the cutoff levels being lower for the GC-MS or LC-MS/MS test.

Although this may not be much fun in the short term, it has to be worth it if it protects your livelihood. We know that lab tests are more accurate than their home equivalent, so a 99% accuracy rate is probably untrue. Realistically, a more truthful claim is that a test has 99% sensitivity insofar as it may detect drugs without outlining the quantity.

If the panel does indicate a positive result, the only way to be completely sure that it’s accurate is to have further analysis in a lab. Once the dip card is in the urine in the collection cup, allow the testing chemicals to react with the urine to identify any drugs that may be present in the sample.
Test options vary in the drug they look for as well as the sample used for testing. There are several options when looking for evidence of drug use, including physician-ordered and at-home drug tests.
