The Most Important Reasons Why Drug Testing Is Important For Drug Testing Labs
If you’ve ever heard the term “drug testing,” you might wonder exactly what it means. Simply put, a drug test is an objective, technical evaluation of a sample, such as hair, urine, saliva, blood, or breath; to determine the existence or absence of specific parent substances or their metabolites. Typically, drug testing occurs in a clinical setting in a doctor’s office or hospital, but it can also be administered by school health care providers or law enforcement officials at any time. There are various kinds of tests currently available and typically, most of them involve either a sample of the person’s blood or a sample of their saliva. These samples are collected from the suspect at specified times and sites; the results are then submitted to lab technicians for interpretation and evaluation.
Drug Testing – Why It’s More Cost Effective Than Many Other Procedures
Most common forms of testing drug involve the collection and testing of samples of a person’s urine. In recent years, many laboratories have begun performing drug tests using the hair as well. This is particularly common in law enforcement settings, where drug use by suspects can be critical to the resolution of a case. However, drug testing done using hair samples has sometimes been criticized on one ground: that there is no reliable method for reliably determining whether or not a drug user is currently using drugs. According to some experts, this is because hair growth slows considerably after drug use cessation, making the hair test invalid; and in cases where users frequently visit salons and regularly wash their hair regularly, many hair tests may be invalidated due to contamination of the hair samples with other forms of bodily secretions.
Although most people think that drug testing requires the detection of every last trace of drugs in a person’s system, that is not necessarily true. In fact, the Food and Drug Administration (FDA) has stated that the only way to determine accurately and consistently whether or not a drug user is under the influence of a particular substance is to do so using a DNA testing method. Drug testing laboratories commonly use DNA testing methods to determine levels of a controlled substance, such as cocaine.
