![]() Similarly, in the federally mandated safety-sensitive workforce, pre-employment positivity increased 9.5% since 2017 while post-accident positivity increased 41.9% during that time. Most concerning, over the last five years, all industries experienced a 17.4% increase in positive test results for pre-employment drug tests and a 26% increase in positive test results for post-accident drug tests. The overall positivity rate for the federally mandated, safety-sensitive workforce (which includes federal employees and certain transportation industry employees) increased in 2021, with notable increases in positive rates for marijuana, amphetamines and cocaine. The Retail Trade industry saw the highest overall drug positivity rate at 7% and also saw a 55.6% increase in positive methamphetamine drug tests between 20.Įncouragingly, the positivity rates for heroin and other opioids over the past year decreased or stayed the same across all workforces. Accommodations and Food Services topped the lists with a 7.5 % marijuana positivity rate. Positive marijuana test results doubled or more than doubled in six of the seventeen industries tracked: Transportation and Warehousing Finance and Insurance Utilities Accommodations and Food Services Retail Trade and Professional, Scientific, and Technical Services. Over five years, positivity for marijuana in the general U.S. Positive urine drug tests for marijuana climbed to the highest rate ever recorded. Not surprisingly, positive marijuana test rates continue to increase. Although the overall positivity rates rose by only 1.8% since 2020, they were 12% higher than in 2017 and have risen steadily over the past five years. Of the seventeen industries tracked, all but mining saw an increase in overall positivity rates from 2017 to 2021. The study was based on more than 11 million urine, hair and oral fluid drug tests collected during calendar year 2021.

Oral fluid drug test common cutoff levels DrugĬommonly ordered non-regulated drug tests: Source. Instant urine drug test common cutoff levels Drug Urine specimen 9-panel drug test cutoff levels Drug Urine specimen 5-panel drug test cutoff levels Drug Lab-based urine drug test common cutoff levels Drug Many non-regulated employers mirror the cutoff levels established by the government while others customize their drug testing panels to be more sensitive to certain drugs based upon their program needs and unique workforce. The US Department of Transportation’s (DOT) rule 49 CFR Part 40 harmonizes with HHS and describes the required procedures for conducting drug and alcohol testing for the federally-regulated transportation industry. Department of Health and Human Services (HHS). Federal drug testing cutoff levelsĬutoff levels for federally-regulated drug testing programs are established based on mandatory guidelines set by U.S. While that may be the case, other possible interpretations are that a drug was present below the cutoff or the testing panel did not include the drug the individual was using. Consequently, a negative drug test does not necessarily mean that no drug is present. Only when a drug or drug metabolite is identified at a concentration equal to or above the administrative cutoff is a specimen reported by the laboratory as positive. It is important to select a specimen type and cutoff level based on the desired window of detection and any regulatory requirements. What does ng/mL and pg/mg mean on your drug screen?Ĭutoff levels are expressed in nanograms (ng) per milliliter (mL) for urine and oral fluid testing or picograms (pg) per milligram (mg) for hair testing. The confirmatory test uses definitive methods, such as chromatography-mass spectrometry (e.g., GC-MS, LC-MS/MS), that specifically identify and quantify the drug/metabolite in the specimen. Choose from a variety of lab tests and test types that best suit your needs. Introducing Quest Mobile, an in-home sample collection option that leverages an extensive network of friendly, trained phlebotomists that travel to you. The initial test is designed to separate negative specimens from further consideration. Lab work on your terms, and now your turf. In workplace drug testing, the industry standard process involves two-tiered testing – an initial screen on one portion of the specimen, followed by a confirmatory test on a second portion of the original specimen. 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. ![]()
