POCT is a common acronym in our industry that stands for point of collection test — an instant or rapid drug or alcohol test. A POCT collection begins with a test administrator using a portable device to screen urine or oral fluid, with the device typically yields a result within minutes. This POCT result may or may not be enough to reflect a final test result for an employer. An instant test can be performed on-site at a place of business or in the field. However, some employers prefer that the test is collected and interpreted by a trained drug testing technician or collector at a brick and mortar collection site.
If an instant test specimen screens non-negative, it is sent to the laboratory for confirmatory testing. The lab will re-test the specimen to determine if drugs or alcohol are present and report a final result. One of four SAMHSA-certified Quest Diagnostics drug-testing laboratories can retest the rapid test specimen to determine if drugs are present.
Employers tend to choose instant testing when the fast turnaround time of drug test results is a key requirement for their program. Although convenience and time are important variables in any program, it’s critical to consider all of the criteria and complexities before making a choice on testing method. Factors to evaluate may include:
- Overall objectives of your substance abuse program
- State laws where your company conducts business
- Added responsibility of collecting and interpreting test results
- Drug panel configurations
- Cutoff levels and device sensitivity
- Susceptibility to donor adulteration or cheating
- Value of an accurate drug test
