  1. How does it work?
    The Intercept® i2he™ Oral Fluid Collection Device is a collection system utilized for lab-based detection of drugs of abuse. Oral fluid is collected under direct observation with the average collection time of just 3-4 minutes. Collection pads are then put into a vial, sealed, and sent to your lab with a completed chain-of-custody form for analysis. Results are reported the next day on negative results, and within 48 to 72 hours for positive confirmation.

  2. Which drugs can you detect in oral fluid?
    Laboratories that have performed proper validations with the Intercept® i2he™ Oral Fluid Collection Device can detect a wide range of drugs from standard drugs of abuse such as marijuana, cocaine and opiates to expanded panels. Talk to your laboratory to help you set up the drug panels and confirmation strategies that will meet the needs of your testing program.

  3. How is the sample collected?
    The donor controls his or her own sample under direct visual supervision. The "collector" really is an observer and not in the "chain-of-custody" - the process most often legally challenged. If the donor wants to challenge the collection, the only person to challenge is the donor. The entire process can be completed anytime, anywhere, and takes just minutes to administer.

  4. What is the stability of the sample, and how is it shipped?
    Specimens stored in the Oral Fluid Specimen Vial may be kept at 39°F to 98°F for up to 21 days (including the time for shipping and testing). Shipping of the specimen is generally done via overnight courier as part of your arrangement with the laboratory.

  5. How is the sample analyzed?
    Oral fluid samples are typically screened in a certified laboratory using enzyme immunoassay technology (EIA), proven reliable for routine drug testing. Your laboratory can help you set up screening and confirmation strategies in accordance with your testing policy.

  6. What is the detection window for oral fluid?
    Just like traditional urine testing, the window in oral fluid testing is different for each drug. What we have found is that oral fluid screening identifies recent usage that can be missed by urine testing. Oral fluid samples provide a close match to drug levels in blood, identifying donors that are under the influence at the time the sample is collected. Since oral fluid testing detects parent drug and metabolites, depending on the drug, the window of detection in oral fluid starts within one hour of drug usage and can last up to three days.1,2

  7. Can oral fluid be adulterated?
    OraSure Technologies has studied a wide range of compounds and techniques available today and has not identified any that can alter the results of the test. Furthermore, the risk of the donor introducing any compound into the vial is highly unlikely since every collection is directly and easily observed. These facts will cut all costs associated with adulterant and dilution testing common with urine testing.

  8. What are the economic advantages of using oral fluid?
    Oral fluid drug testing, with its "anywhere/anytime" collection process, results in significantly lower costs associated with collections, scheduling fees, and lost time away from work. Oral fluid collections reduce the labor costs for gender specific collectors and shy bladder syndrome (can't go) and eliminate adulteration testing - all of which contribute to the higher costs of urine testing.

  9. How soon can you expect your results?
    The lab receives samples via overnight courier. Testing is performed the day samples arrive, and negative results are reported within 24 hours. Positive results are confirmed, scientifically reviewed, and reported within 48 to 72 hours of receipt.

  10. Isn't oral fluid a biohazard?
    No. OSHA does not consider oral fluid collection hazardous. In addition, oral fluid specimens are not subject to the same handling and disposal procedures that are issues with other bodily fluids.
