In addition to the standard 5-panel and 10-panel drug screens described below, specialized urine testing screens can also be used to test for the presence or use of alcohol and nicotine.
- EtG Urine Testing for Alcohol: This specialized form of urinalysis tests for the presence of ethyl glucuronide (EtG). EtG is a byproduct of alcohol when it is processed and metabolized in the liver and flushed out of the body in urine.
- Cotinine Testing for Nicotine/Tobacco Use: Cotinine is a byproduct of nicotine and can be used to determine whether or not a person is an active tobacco user, as well as how recently a person has stopped using tobacco products.
Standard 5-Panel Urine Test
The following substances can be detected using our 5-panel urine tests:
- THC (Marijuana)
Expanded 10-Panel Urine Test
The 10-panel, as well as the five panel, test is often used to determine whether prescription drugs are present. These panels offer flexibility and can be custom-tailored to your needs. An example 10-panel test might search for:
(all substances from the 5-panel) plus
- Propoxyphene *
- *Other drugs may be substituted, such as MDMA, Oxycodone and extended opiates
NOTE: Synthetic drugs can’t be detected on 5- or 10-panel test. They require a separate urine test.
Urine Testing Procedure
Urinalysis drug screens take place at a collection site, typically a private bathroom or bathroom stall, where you produce and deposit the urine specimen into a specially designed secure cup. You will not be allowed to take purses or other personal items into the room or stall with you. The technician receives the sample from you. They may perform initial testing on site or seal the specimen with tamper-resistant tape, typically in your presence, and package it for transport to the lab for testing.
An immunoassay test contains antibodies to the specific drugs (antigens) being tested. This is typically the initial drug test performed. If any of those drugs are present, the antibody will bind with the antigen. In the test, the chemical reaction in the sample causes it to change color, and the color is compared with known benchmarks to determine whether the test qualifies as negative or non-negative.
A second test from the same specimen takes place if there is a non-negative result. The second test is by a different and more specific process, called gas chromatography/mass spectrometry, or GC/MS. GC/MS is a two-stage process that vaporizes a small amount of the sample into gas so that it can be separated into its distinct chemical components and specifically identified. GC/MS testing is considered the gold standard in forensic chemical testing.
Employers, including the United States Department of Transportation (DOT) and agencies and contractors that must abide by its rules, take a “split specimen.” At the time of collection the sample is separated into two vials. The first is tested immediately according to regular procedures described above. The second belongs to the sample donor and is available for secondary testing if they disagree with the initial test results.
If the technician administering the test has reason to suspect that you have tried to tamper with the test results in some way, either by dilution, adulteration or substitution, they can request that you produce another specimen under direct observation.
