What Are The Cutoff Levels For Drug Testing?

What is the difference between a screening test and a confirmation test for drugs?

What does cut off level mean in drug testing?

What does “Cut-off level” mean? Essentially, it means separating the positives from the negatives. In drug and alcohol testing, a cut-off level is a level at which the concentration of a substance in your breath, urine, or saliva, indicates a safety risk.

What happens if my drug test comes back positive?

If the test results in a positive reading, meaning there is drug residue in the body, the results are forwarded to a medical review officer, who reviews the results and looks for any possible valid medical explanation for the results.

What is the difference between screening cutoff and confirmation cutoff?

False negatives often occur because screening cutoff levels are unable to detect positive samples at low concentration levels. The other category of testing is quantitative testing, or confirmation (also known as “definitive testing”).

Can body hair be used for drug testing?

Unlike head hair, body hair drug testing can only show a history of drug use sometime between 30 days and a year in the past. A body hair sample is typically collected by cutting or shaving hair from the arms, legs, chest, stomach, underarms, or face of a male donor.

What happens if you fail DISA drug test?

If one of your employees fails a drug screen and they are in a safety-sensitive position, they must be removed from duty immediately. If the employee is not in a safety-sensitive position, then disciplinary actions can vary based on company policy.

What is the cutoff level for a hair drug test?

Cutoff Levels To use the cannabinoid example, our screening cutoff level for the cannabinoid drug class in a hair specimen is 1 pg/mg. If any of the hundreds of cannabinoids cumulatively register above this cutoff level, the specimen would go into confirmation testing.

How much is a ng mL?

Some medical tests report results in nanograms (ng) per milliliter (mL). A nanogram is one-billionth of a gram.

Will a job still hire you if you fail a drug test?

Pre-employment screening can be more straightforward than screening for existing staff, Phillips said. If an employer makes a job offer contingent on passing a drug test, the offer can generally be rescinded if the applicant tests positive. There may be more steps employers must follow for current employees.

What is a confirmation drug test?

Confirmation tests provide qualitative results of drugs and/or drug metabolites present in the sample. Drugs are rapidly metabolised in the body to aid excretion and detection of the resulting metabolites indicates drug use by the donor. Sometimes it is only the metabolites that are positive in a confirmation test.

How long does a confirmation drug test take?

The sample’s transit alone can take 24-72 hours. And while the MRO receives the initial results fast digitally, it could take them up to 96 hours to confirm test results if the donor is difficult to reach. The good news for employers is that results are presented much more quickly when test results are negative.

What does ng/mL mean on a drug test?

Nanograms per milliliter, abbreviated ng/mL, is the unit of measure most commonly used to express drug testing cut-off levels and quantitative test results in urine and oral fluid.

How sensitive is a 10 panel drug test?

About the 10 Panel Drug Test Illicit drugs, also known as street drugs or simply illegal drugs, are almost never prescribed. Amphetamines, barbiturates, benzodiazepines, cocaine, marijuana metabolites (THC), methadone, methaqualone, opiates, phencyclidine (PCP), and propoxyphene can be detected with this test.
