Inconclusive resultsĪn inconclusive result means the test was not successful. It does not indicate that the person has never used the drugs or that they will not use the drugs in the future. Negative resultsĪ negative result indicates that the drugs tested for are not present or are not present in a high enough quantity to detect. This precaution helps protect the individual from disciplinary action due to false positives. This finding suggests they have used the drug recently.Īs the Substance Abuse and Mental Health Services Administration point out, federal employees and employees in many other safety fields have the right to have a second lab test their specimen if they receive a positive result. Share on Pinterest If a person has detectable amounts of certain drugs in their system, the result will be positive.Ī positive result indicates that the drug or its byproducts are present in the person’s system in detectable amounts. With that said, most samples will go to a lab for analysis, which can take a few days. Some tests offer onsite results that can analyze the urine samples straightaway. When they receive the sample, the lab will test the urine for the 10 different drugs. They then close the container with the lid and give the sample to the test administrator. The person starts urinating and collects urine in the collection cup during the middle of their urine stream. In rare cases, a same sex administrator stays in the room with the person to be sure they take the test. This can make the test more accurate and prevent tampering. If an administrator is concerned with contamination, they may take precautions such as turning off tap water in the bathroom or adding a dye to the toilet water. In some cases, the administrator may ask a person to use a particular bathroom stall to take the test. Bathrooms are common locations, as these tests require urine. The test environment may differ depending on who administers the test. These may include not urinating for a couple of hours before the test or avoiding drinking extra water before the test. The test administrators may have special preparation instructions as well. Some professions may require the person to agree to random drug testing where they have little to no knowledge of the test beforehand. If a company or organization requires a person to take a 10-panel drug test, they will generally give them notice of about 24 hours. The following table provides a rough estimate for detection times for various drugs via urine tests: Drugĥ–7 days for moderate use (4 times per week) The tests measure byproducts in the body that come from breaking down the drug, so they cannot detect how much of the drug is circulating in the body. Detection times for different drugs vary greatly.ĭetection times may depend on the type of drug, how much the person took, and how fast their metabolism works.Īnother important fact to note is that a 10-panel drug test will not tell if the person is currently on the drug. While a 10-panel drug test may help screen for drug use, it has limitations.ĭetection times refer to the amount of time it takes for the body to get rid of the byproducts of the drugs.
