Sweat Drug Screen - Sweat Drug Testing
Another form of testing that is not very popular is a sweat drug screen. This test works by affixing a patch to someone’s skin. This patch gathers a person’s sweat over an extended period of time (10-14 days) The patches have a security feature that will show signs that it has been tampered with and then reaffixed without the knowledge of the one doing the testing. These sort of tests are only really used by CPS, parole departments and government offices. The reason for using this sort of test is when there is a concern over someone using over a long period of time, when a urine test would not prove as effective. However, this form of test has fallen into disuse by the government because of documented issues with this test regarding certain drugs.
Pros: Sweat test are non-invasive and donor friendly. Specimen collection is easy and no bathroom is required for specimen collection. The detection window is prolonged and most of the time can detect drug usage for a time period of a couple of weeks. They are pretty much tamper proof because they are difficult to manipulate. There is no lab needed and results are obtained within minutes.
Cons: The main disadvantage is the fact that they are open to contamination. Also, there are large differences in sweat production rates of donors that can make some test results inconclusive. There is also little variety in these tests due to their lack in popularity. Cost for these test are usually a little and they are limited by the number of drugs that they can detect.
