Frequently Asked Questions
Which drugs can you detect in oral fluid?
Intercept™ oral fluid drug test is a laboratory based
test which can detect: marijuana,
opiates, amphetamine, methamphetamine, benzodiazepines and cocaine, which represent the most common drugs
requested by employers for workplace drug testing. Other assays (methadone, barbiturates, PCP) are available to service the needs of the health and
corrective services, life insurance companies etc. All assays are FDA
cleared, in compliance with the new oral fluid cut-off levels from DTAB
(Drug Testing Advisory Board).
2. How does the detection window for
oral fluid testing compare with other methods?
Just like traditional urine testing, the window in oral
fluid testing is different for each drug. But unlike urine
oral fluid testing identifies "current usage"
- during the first four hours after drug use - that can
be missed by urine testing. For most drugs, the window
of detection in oral fluid is measured in hours ("same-day
use"). By contrast, urine testing relies on drug
metabolites retained in the body's waste system with a
detection window that is measured in days ("recent
use"). For a complete comparison of a traditional
laboratory based urine drug test and the Intercept™ oral
fluid drug test see: Urine
vs. Oral Fluid.
3. What methodology is being employed?
Oral fluid samples are first screened in a
laboratory using enzyme immunoassay technology, proven
reliable for routine drug testing. Any samples that test
positive in the screening process are then subjected to gas
chromatography/mass spectrometry-mass spectrometry (GC/MS-MS), the latest in drug confirmation technology. This
tandem "MS", as it is called, provides the most sensitive
fingerprint available, of the drug being targeted.
4. Can an oral fluid test be
A wide range of adulterants have been studied
but nothing have been and
have not found that can beat the test. Of course, donors
may attempt to introduce something onto the pad or collection
vial, but since every collection is
directly and easily observed it is highly unlikely they will
5. Who collects the
The beauty of oral fluid testing is that the
donor collects his or her own sample under direct visual
supervision. The donor places the collection pad in his or her
cheek and gum for at least two minutes. Once the absorbent
collection pad is saturated, it is placed in a vial, the
handle of the collection device is snapped off at the rim of
the vial, the vial is sealed, and the donor initials the seal.
The entire process takes just 5 minutes and is very
cost-efficient compared to urine.
6. How much
does it cost?
Oral fluid can be significantly less
than traditional urine testing. The economic advantage of the
Intercept™ oral fluid drug test is that it can reduce the cost
of collections, scheduling fees, and the time lost for
employees to travel to collection sites to provide their urine
7. What is the turnaround time?
results of the 20 screening tests in the starter kit will be reported
within a couple of days.
8. Isn't oral
fluid a hazardous fluid?
No. Because the testing
methodology is not classified as a "dental process," oral fluid
collection is not considered hazardous. In addition,
oral fluid specimens are not subject to the same handling and
disposal issues that face other body fluids.
How do you know if you have enough sample to test?
the donor keeps the collection pad in his or her mouth for at
least two minutes, as indicated on the package, there is
enough to test. The collection pad is treated with salts to
stimulate oral fluid secretion, making the process very
reliable. In fact, based on experience from life insurance
testing, LabOne (in the USA) reported only 1 in 10,000 samples insufficient
