Collection: Mouth Swab, Oral, and Saliva Drug Test

10 products

Mouth swab drug tests are also commonly referred to as oral drug tests, cotton swab drug tests, or saliva drug tests.

These tests are often preferred because they are less intrusive than urine tests, blood tests, or hair follicle tests, and they are less likely than urine screens to provide a false result.

The heightened accuracy of saliva drug tests primarily comes from the fact that it is more difficult to produce a fake sample. There are people who believe a saliva test can be cheated by frequent brushing of the teeth and extra hydration, but these methods are not scientifically sound.

It is also important to note that saliva tests have a relatively short detection window, with most drugs requiring testing within 24 hours of being consumed, smoked or injected. We recommend looking into the saliva drug test detection times for each individual substance before determining if a swab test is right for you.

What is a mouth swab test?

A mouth swab test is a form of immunoassay screening that measures the presence of antibodies in the blood to determine if an individual has ingested a particular substance. This is made possible by the body’s immune response to foreign chemical compounds. Once a drug enters the human body, the immune system automatically produces antibodies to help process the unknown substance and protect the body. These levels of these antibodies are what a drug test measures before providing a negative or positive result.

What drugs can a cheek swab test detect?

Please refer to the list below for a complete breakdown of substances that mouth swab drug tests can screen for:

  • Alcohol
  • Marijuana
  • Cocaine
  • Amphetamines
  • Barbiturates
  • Benzodiazepines
  • Methadone
  • Methamphetamine
  • Opiates
  • Oxycodone
  • Phencyclidine

It is important to note, however, that the number of drugs a test can detect will depend on the type of test purchased.

What can be done to ensure the accuracy of a mouth drug test?

We recommend taking the below precautions when administering a mouth swab drug test:

  1. Advise the individual not to eat or drink anything before their test, and to avoid brushing their teeth (if possible). For this reason, it is often best to perform a swab test early in the day.
  2. Open your sealed swab immediately before performing the test. This eliminates the possibility of the swab being contaminated or coming into contact with other surfaces, bacteria, etc.
  3. After collecting the DNA sample, carefully return your swab to the provided tube and ensure it is properly sealed. This should happen within 60 seconds of collection to ensure the most conclusive results.
