All methods are effective, but you'll want to choose one that's right for your specific circumstance. Urine drug tests require a sample of urine, which is collected in a small cup. A test strip is dipped into the sample, and results are produced within minutes. This type of test is affordable and can detect a substance for a week after use.
However, collecting the sample requires giving an individual privacy, which makes the sample vulnerable to tampering. Saliva drug tests require spitting into a sample cup or swabbing the insides of the cheeks. Test strips are also used, and the process is less invasive and less vulnerable to tampering than a urine test. Saliva tests, however, can only test the presence of a substance within a 24-hour window of use. Hair follicle drug tests are the most accurate of the three types. These require a hair sample, cut or plucked close to the scalp, to be mailed to a lab in an envelope provided by the manufacturer. This test is tamper-proof and will show the presence of a substance within 90 days of use, though it won't show use as recent as three to five days. This is the most expensive test type, and results take about a week to get back from the lab.
FDA approval: Only select drug tests that carry FDA approval so that they are guaranteed to accurately test the drugs they claim to. CLIA certified: For hair follicle tests, select one that's been CLIA certified to ensure the laboratory meets regulatory standards. Drug tests range in price due to a number of factors, like how many tests are in the kit or how many drugs the test can detect. Typically, a urine drug test is priced at $10 to $30 for a kit containing five or more individual tests. A saliva drug test ranges from $11 to $85 for a kit with two or more individual tests. A hair follicle drug test ranges from $50 to $95 for an individual test that can detect multiple drugs. While home drug tests are sensitive, they aren't 100% accurate. False positives can result if an individual has taken certain legal medications, supplements, and even certain foods or beverages. This is why we recommend taking your sample to a professional laboratory to confirm the results. False negatives also occur for a number of reasons: the test is expired, the test was given too soon after an individual used a substance or too long after. You may also get a false negative if an individual abused a drug that the test wasn't designed to detect. Our take: A urine test for THC with lab-level accuracy. What we dislike: Some results can be difficult to read. Our take: A multi-drug urine test that boasts over 99% accuracy. What we like: Detects marijuana, meth, cocaine, opiates, and amphetamines. Ability to test opiates like morphine is six times greater than other tests.
