Trying to enforce a safe and drug-free workplace for your business throughout Trenton? A drug-free workplace program can help you accomplish just that so that you can improve workplace safety, increase productivity, and you may even receive a discount on your workers’ compensation insurance. Several states offer the incentive, and the savings ranges from four up to ten percent.
We provide a wide range of drug screening services for your business in Trenton that enable you to screen out new employees who have a substance abuse problem, discourage current staff from using drugs, and identify those who do. All while maintaining DOT compliance if you’re regulated, or just freeing you up to focus on other parts of your business if you’re not. And we can conduct screening at your location or ours, 24/7/365.
Unlike traditional laboratories, USA Mobile Drug Testing is here 24/7—and we travel to you to minimize downtime. When we’re managing your entire drug-free workplace program, you get all of the benefits without dealing with the administrative details. With us in charge, you can be sure your workplace drug testing is performed on time, every time, no matter where your employees are or when you need them tested.
You don’t need to interrupt your employee’s sleep cycle to go to a testing facility during regular business hours. Never again will you have to pull staff off-site for drug testing at a facility leaving your crew short staffed. We roll up on-site—no matter where it is—totally prepared to professionally administer the test.
When should you perform drug testing
If your business is regulated by the Department of Transportation, you are required to follow particular guidelines on workplace drug testing. Many employers of non-DOT-regulated companies follow those same regulations when developing their own drug free workplace program.
USAMDT offers Trenton businesses a program that tailors your drug testing policies to meet your specific needs. We’ll even develop and then implement your policy, and provide employee education and staff training at your request.
There are many reasons to perform workplace drug testing, including:
Pre-employment drug testing
The Department of Transportation requires an employee to have a negative drug test result on file before a driver is permitted to get behind the wheel. Many employers of the general workforce require a pre-employment drug test before a new hire begins work as well.
Random drug testing
Most people associate random drug testing with Department of Transportation regulations, however, it’s common in other industries too. The department requires all members of a safety-sensitive workforce to have their names added to a random pool. The pool is used to randomly create a list of employees who are required to take a drug test.
DOT drug testing
The DOT requires that all members of a safety-sensitive workforce have been drug tested before they use a commercial motor vehicle (CMV). Additionally, drivers are entered into the random test pool and may be called up for drug testing periodically throughout the year. Post-accident, probationary, reasonable suspicion, and return to duty testing are also mandatory.
The DOT requires a urine test and tests for the following drugs:
- Amphetamines and methamphetamines
- Cocaine
- Marijuana
- PCP
- Opiates including synthetic opiates
- Oxycodone
- Oxymorphone
- Hydrocodone
- Hydromorphone
Reasonable suspicion drug testing
Train your management staff to identify the signs of substance impairment. If they suspect someone is impaired, they should know the company policy and document everything before approaching that employee. The suspected employee must then report for drug-testing immediately.
Post-accident drug testing
If there is a workplace accident, drug testing all employees involved can help determine who is responsible and protect you from legal liability.
Return to duty drug testing
A certified SAP (Substance Abuse Professional) works with the driver, or other safety-sensitive employees, who have tested positive for drugs. The SAP signs them off as able to return to work after that safety-sensitive employee has a negative drug test result.
Drug testing methods
We can administer drug tests throughout Trenton using several different methods, depending on your needs. Each method has pros and cons, and you should speak to one of our specialists if you need advice on deciding which is best for your circumstances.
All test specimens go through an initial screen. The immunoassay (IA) test identifies a positive or negative result. The majority of drug tests are negative and this cost-efficient test saves employers money because no further testing is needed.
Tests registering a positive result go on for confirmation testing. The gas chromatography/mass spectrometry (GC/MS) test confirms the positive result by identifying the drug and the level contained in the sample.
Urinalysis
The industry standard is the urinalysis. (This is currently the only testing method the DOT will accept.) Urinalysis is quick, easy, and inexpensive, but it does come with a few drawbacks.
You need to secure a private bathroom, and you must disable the sink and toilet, and pour a bluing agent in the water in the toilet bowl. Privacy concerns may also present an issue because a test must be performed by an administrator of the same sex.
In addition, the privacy factor also provides an opportunity to attempt to cheat the test by adulterating the specimen, which creates a negative dillute or positive dillute drug test result, or even substituting the specimen entirely. However, technological advances in both testing procedures and lab equipment make it increasingly difficult for drug users to succeed.
This testing method can identify drug use from about a half-hour after use up to a few weeks after the last use. Chronic marijuana use is an exception to the rule. Habitual users can test positive for up to thirty days. You can learn more here: How Long Does Marijuana Stay in Your System?
Employers receive test results in a few days.
Mouth swab / oral fluid
This method of drug testing is somewhat newer, but is still just as accurate as urine drug testing. It’s also just as quick, simple, and inexpensive. It offers the smallest detection window though. Still, it identifies most drugs within just a few minutes of use. It only identifies drugs for a period of up to 72 hours prior to the test.
The most powerful advantage of the mouth swab drug test is that it can be conducted literally anywhere—even in plain view of other employees. The test only requires placing a mouth swab between the lower cheek and gum. The employee holds it in place until it becomes saturated. The process rarely takes more than 5 minutes. Despite the claims we hear many drug users make, the only way to pass a mouth swab drug test is to not use drugs.
Results are received in just a few days.
Because it detects recent drug use, it’s becoming a popular option for random drug testing. In fact, the HHS (The Health and Human Services Administration) approved the use of this testing method as an alternate drug testing method for all federally mandated employers as of January 1, 2020.
At this time, it’s unclear whether or not the DOT will incorporate the test into its regulations.
Hair
The less common hair follicle drug test offers the same ease as mouth swab testing, however, it’s more expensive.
The fact that it offers a 90-day detection window overrides the added cost in the eyes of more and more business owners. In fact, the DOT officially requested that the hair test replace the urine drug test. The request is passing through the chain-of-command and many expect to hear the final word anytime now.
This test requires the administrator to cut a small (less than 1” wide) section of hair, preferably from near the base of the scalp, and secure it in a zipper-lock plastic baggie. While this testing method is easy and convenient, some employees may have a problem with having their hair cut.
No worries.
Body hair can be used instead and is tested by volume rather than length. Administrators collect enough hair to equal the size of a cotton ball about an inch in diameter.
Body hair provides a longer detection window than head hair. Hair collected from an employee’s head can detect drug use for up to 90-days, while hair collected from the body will detect drug use for up to a year.
The hair test can’t detect current impairment or very recent drug use.
