Articles > How do they do drug testing?How Do They Do Drug Testing? - Drug Testing Basics Drugs eventually show up in your body fluids (blood, urine and saliva) and hair in one form or another. So, you'll be asked to "donate" a sample (specimen) of one of them, which is submitted to a drug testing lab for chemical analysis. Hair Drug Testing Because your hair grows, certain drugs (THC, cocaine, and others) can be detected for longer periods historically, but typically only for heavy-duty and continuous use. Hair analysis is the least invasive, but might not reveal recent use. Blood Drug Test Blood analysis is the most accurate, but pricey, definitely invasive, and not allowed in the Federal drug testing program at this writing. Saliva Drug Test Saliva and sweat analysis are accurate, but not yet popular methods at this writing. Urine Drug Testing Urine analysis is less invasive than blood analysis, typically the least expensive, and can detect infrequent or recent single use. For these reasons, urine drug testing is the most common drug test, so a urine specimen is likely what you'll submit. It's also what we'll stick with when referring to your specimen. If the specimen-collection facility goes by the book, you'll start by replacing some or all of your street clothing with one of those hospital-type gowns that lets your backside stick out, to reduce the likelihood that you can smuggle something in to tamper with your specimen. Then an escort will steer you into a "dry room" that doesn't have much in it, to further prevent you from tampering with your specimen. In the absence of a dry room, it might be a restroom with the faucets turned off at the main valve and colored water in the toilets, also to prevent tampering. In either case, your escort might observe you or hover nearby while you urinate in the vial. Then your specimen is off to a drug testing lab, where they'll typically test it for the drug itself or the substances (metabolites) produced by your body when it processes (metabolizes) the drug. If they follow the Federal drug testing guidelines, they'll perform an initial screening and then confirm the results with more sophisticated tests. Under the Federal guidelines, drug testing has two cutoff levels for positive detection. That is, labs that follow the guidelines consider drug testing to be negative if detection is below either cutoff level. In the case of urine analysis, drug testing cutoff levels are measured in nanograms per milliliter (ng/ml). For example, an initial screening for marijuana must show at least 50 ng/ml, and then confirmatory tests must prove at least 15 ng/ml. If the initial screening doesn't show at least 50 ng/ml, then it's considered to be negative and the confirmatory tests aren't performed. Drug testing can be a serious challenge for your career, therefore you should be prepared for drug testing no matter what circumstances can happen before it. But remember, there is a way out of the most complex situations. Pass Blood Drug Test Pass Hair Drug Test Pass Saliva Drug Test Pass Urine Drug Test Not sure what kind of drug test you may face?
