Screening and confirmation testing are performed using different methodologies that require different cutoff levels. The cutoff levels of an immunoassay (screen) are typically higher than those of a more sensitive GC-MS or LC-MS/MS confirmation test. The reason is that they test for a larger group of parent compounds, metabolites and other structurally similar compounds. If [...]
Understanding drug test results can be a challenging task. Here are some details to help with the understanding drug test results: Positive – Presence of drugs above the cutoff level Adulterated – Something has been done to alter the sample Shy Bladder – Inability to provide a sample Substituted Specimen / Invalid Specimen – Substance [...]
Drug testing detects the presence of drugs and drug metabolites using cutoff levels to determine whether a specimen tests positive or negative for the use of a specific drug. A cutoff level is a threshold. If the concentration of a drug is above the cutoff, it is a positive result. If it is below, it [...]

49 CFR Part 40 requires that a donor be allowed up to three hours after an initial failed attempt to produce a sufficient urine specimen. During this time, the donor may drink up to 40 ounces of fluid spread over the three hour period. For this reason, many collection sites have a cutoff time for [...]
Question: If an employee is not able to provide enough urine during the collection process, and the employee must undergo a medical examination to determine if there is a legitimate medical explanation for the “shy bladder,” can the employer make arrangements for the employee to see an employer-designated physician? Answer: Yes. When an employee is [...]
Yep. It happens. We catch a lot of them, but some inevitably slip though. Remember that your drug testing program is mostly about deterrence. We get a fair number of positives, but there would be a lot more drug use if there were no testing at all. A number of safeguards in the collection process [...]
Labs conduct specimen validity testing which detects adulterants. With hair and oral fluid testing, adulteration is much more difficult than with urine.
If he’s a regulated employer, no. A regulated employee (e.g. driver, under FMCSA) must complete the Return-to-Duty process. If he wants to return to work as a driver, he must contact a Substance Abuse Professional (SAP) and complete the Return-to-Duty process — even if he is not hired or is terminated. Your company’s drug and [...]
Seems like it might be. But it’s not. A workplace drug test is a toxicology test, whereas a medical test is a clinical test. In fact, these tests are conducted in different facilities on different equipment. Labs like Quest Diagnostics and Labcorp conduct clinical tests and toxicology tests in totally different cities.
