# Quick Answer: What Are Drug Screen Cutoff Levels?

## What happens when you fail a drug test with DISA?

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..

## How much is an NG?

A nanogram is one-billionth of a gram.

## How do you calculate ng mL?

Note 4: If the lab value is expressed in IU/ml, use the following conversion: 1 ng/mL = 0.83 IU/mL.To calculate ng from IU/mL, divide the value for IU by 0.83.Example: 10 IU/mL: 10/0.83 = 12.04 ng/mL; 5 IU/mL: 5/0.83= 6.02 ng/mL.

## What do drug test cutoff levels mean?

In the case of urine analysis, drug testing cutoff levels are measured in nanograms per milliliter (ng/ml). For example, an initial screening for marijuana must show at least 50 ng/ml, and then confirmatory tests must prove at least 15 ng/ml.

## How accurate is drug confirm?

If the test results are negative, can you be sure that the person you tested did not abuse drugs? No. No drug test of this type is 100% accurate. There are several factors that can make the test results negative even though the person is abusing drugs.

## What’s the difference between a drug test and a drug screen?

A drug test is often more reliable and provides an accurate analysis of an individual’s substance use. Major corporations typically prefer testing over screening. On the other hand, drug screening is a more cost-effective approach, as it is relatively cheaper than a drug test.

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

Compared to screening, confirmation testing has many advantages. LC-MS/GC-MS testing is far more sensitive and specific than qualitative screening, so confirmation results are much less likely to produce false negative or false positive results.

## What does screen and confirm mean on drug test?

The Screen Threshold and Confirm Threshold are the standard cutoff levels that the laboratory uses when testing a specimen. When the laboratory first receives the specimen, they run the Immunoassay test or Screen test. Immunoassays use antibodies to detect the presence of a drug or metabolite in the urine.

## How many nanograms does labcorp test for?

Just as for other types of lab tests, both screening and confirmatory tests are interpreted based on a defined cutoff level (e.g., 50 nanograms per milliliter (ng/mL) for urine samples).

## What does a 10 panel drug test test for?

Standard 10-panel test: typically looks for cocaine, marijuana, PCP, amphetamines, opiates, benzodiazepines, barbiturates, methadone, propoxyphene, & Quaaludes. 12-panel test: often administered as an extension to the 10-panel test.

## How long does it take to get below 50 ng/mL urine test?

Analyzing urine samples at a 50 ng/mL immunoassay cutoff yielded an average cannabinoid detection time of 42 hours. These acute marijuana elimination studies conclude that after single usage events cannabinoids are detected in urine for no more than a few days.

## How long does it take to get 10 panel drug test results?

The results should be available within a few business days. Drug test results can be positive, negative, or inconclusive: A positive result means that one or more of the panel drugs were detected at a certain concentration.

## Is an at home drug test as accurate as a lab test?

While home drug tests are sensitive, they aren’t 100% accurate. False positives can result if an individual has taken certain legal medications, supplements, and even certain foods or beverages. This is why we recommend taking your sample to a professional laboratory to confirm the results.

## How long does it take to get urine drug test results?

Drug test results typically take 24 to 48 hours, depending on the type of test being performed (e.g., urine, hair or DOT).

## 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.
