Employers can choose the best drug test type to build an effective program.

Urine drug testing – Urine is the most common and trusted test method. It detects recent drug use, typically in the previous 1 to 3 days, and can be performed for a wide range of illicit and prescription drugs.

Oral fluid testing – The Oral-Eze® oral fluid collection system is one of the most utilized collection/testing system for workforce oral fluid testing and is second  to urine testing in workforce testing volume.  This screening method and detects recent drug use in the previous 24-36 hours. Data also shows that Oral-Eze is very effective in detecting marijuana use.

Hair testing – Hair drug testing continues to gain broader appeal as it yields a longer detection window, providing a drug-use history that shows up to a 90-day pattern of repetitive use.

Instant urine drug testing – Instant urine drug testing can provide a result on-site, allowing the option to have drug test collections take place outside of a collection site so employees are able to go back to work the same day.

Alcohol testing – Our implementation of electronic breath alcohol testing (eBAT) helps make the process more seamless and effective.

There are reasons beyond pre-employment that employers choose to drug test employees. Some workforce scenarios include:

Random – Using a random selection process, the employer selects one or more individuals from all the employees included in the employer’s workplace drug testing program. Random testing is a strong deterrent to drug users because it is conducted on an unannounced basis.

Reasonable suspicion – Sometimes referred to as “probable-cause” or “for-cause” testing, this testing type is usually unscheduled or short notice and is conducted when a supervisor has evidence or objective reasons to suspect drug use by an employee. Since this type of drug testing is discretionary, it requires supervisor training to ensure consistent application of the program across the workforce.

Post-accident – Testing following an accident—sometimes referred to as “post incident” testing—can help determine whether drugs were a factor. Post-accident testing should be done within 12 hours of the incident since different drugs may have different windows of detection.
