DrugStop Saliva Screening Kits – Information for Use

Saliva density and volume varies from person to person.


To help you get the best results from your DrugSTOP Screening kits we have put together these brief instructions:

  • Make sure the donor has not had anything to eat, drink or smoke within the last 10 minutes.  This is to ensure the mouth is free from any contamination that COULD affect the test results.
  • Ensure the test kit is in date.  The kit uses a live antibody which has a finite lifespan – expiry date of the test kit will be found on the outer packaging.  Using expired kits may lead to invalid results.
  • Prior to taking the sample, ask the donor to move their tongue side to side, up and down in the mouth to generate additional saliva.
  • Donor should rub the collection swab around the inside of both cheeks then place the swab under the tongue – do not chew or suck the swab.  The kit can be held in place using teeth on the plastic casing.
  • Holding the head in a down position during saliva collection will use gravity to help ‘pull’ the saliva onto the test kit.
  • Set a timer for 3 minutes and check to see if saliva is visible in the results window.  If not, continue to hold swab in place for up to 10 minutes.  If no saliva is visible after 10 minutes, test is invalid.
  • Read test results 10 minutes after successful collection.

 

Interpreting the results

Saliva drug screening is very similar to COVID Lateral flow testing – with one MAJOR difference:

With Saliva Drug Screening, an ABSENCE of a line is indicative of a POSITIVE result.

Check:

  • Control Lines (marked ‘C’ on the test kit) = all Control lines should be visible.  If not, test invalid.
  • Result line present = NEGATIVE result
  • Result line absent = POSITIVE result
  • Line intensity will vary from drug type to drug type, person to person.  This is not a reflection on the ‘quantity’ of drug in a person’s system.  ANY line present indicates a NEGATIVE test result.
