As we know, there are a number of various drug tests that can be administered. The detection time frame for substances differs with each specific test ordered. Thus, detection of a toxin in a saliva test can only go as far back as few days, whereas detection in a hair test can reveal a history of use in the past 3-4 month.

We recently were asked a question – if a saliva test determines recent usage, what is the difference between that and a breathalyzer test?

First of all, the breath analyzers are used solely for alcohol detection; saliva test can detect a variety of toxins. Secondly, breath tests are widely used by police to establish eligibility of a driver to operate a vehicle, whereas saliva tests are usually used at a job environment. Both tests are available to general public as you may be interested in testing yourself or somebody you know for recent drug use, or when deciding whether to drive home after a party or to call a cab. Saliva home test kits present a little strip or a sponge that is put under a tongue in the mouth and absorbs the liquid, which is then tested by coloration of a reactor pad. Disposable breath analyzers are small tubes filled with yellow crystals; the crystals turn green or blue if a person blowing in had drunk too much – above the legal limit not permitting an operation of a motor vehicle.

Depending on toxins you wish to test for you can choose a product suitable for your needs. Remember that a breath test cannot detect use of anything other than alcohol, whereas saliva test checks for alcohol and a variety of toxins.
