Most Common Kits Used in Drug Testing
from: Kathryn WhittakerIf you’re thinking of employing a drug test, you should be aware of the different kits out there. Here are some pros and cons of various testing kits, which will enable you to choose the most suitable kind.
• Urine drug tests and testing kits
These are the most commonly used tests. Results show the presence or absence of specific drugs in urine. If a urine test returns positive, it does not mean the donor was under the influence of drugs at the time but that he or she used them recently. Up to ten drugs at a time can be tested with urine samples.
There are three forms of urine drug tests, namely dip form, cassette form and cup form. With dip form, the test is dipped into a urine sample. With cassette form, a urine sample is placed in a cup and is then transferred to the testing device via a pipette. A cup form test allows for the urine to collect and be tested simultaneously.
• Saliva drug tests and testing kits
A saliva drug test kit detects traces of drugs found in the fluids of a person’s mouth. This kind of test simply cannot be contaminated because it is performed under strict supervision. However, the downside is a saliva drug test can only determine current use of drugs – not previous. Saliva tests are often preferable because they are non-invasive and easy to conduct. At least six types of drugs can be tested this way.
• Hair drug tests and testing kits
Hair drug testing is one of the most reliable forms of testing available, because hair stores traces of drugs for long periods of time. Through this form of testing, one can gain a more complete knowledge of a subject’s drug use history – reaching as far back as ninety days. However, current impairment is beyond this test’s detection.
• Spray drug testing kits
Spray drug tests are especially easy and simple to conduct. They are also very reliable and difficult to manipulate or contaminate. However, the types of drugs a spray drug test can detect are limited.
