Urine Drug Screens
Urine drug testing is widely used for testing for opioids and illicit drugs. There are two types of tests: a screening test and a confirmatory test.
The screening test uses an immunoassay to look for the parent drug and/or metabolite. Most tests screen for marijuana, cocaine, opiates, PCP, amphetamines, while some also test for benzodiazepines, methadone and more..
The confirmatory urine drug test is done by gas Chromatography/mass spectrometry or high-performance liquid chromatography; this test is highly specific and is typically used when testing for the presence of a specific drug is needed.
Hair Drug Screens
Hair testing analyzes a hair sample for parent drugs and their metabolites. A hair specimen, collected from a donor’s head or body, is sent to the laboratory and is screened for illicit substances.
Reportedly, hair testing produces five times as many users compared to laboratory based urine testing programs.
The typical length of head hair tested is 1½ inches from the root end. Since the average growth rate of human head hair is approximately ½ inch per month a hair analysis covers an approximate 90 day time frame.
Nail Drug Screens
Fingernail drug tests are designed to detect the residual presence of amphetamines, methamphetamines, cocaine, opiates, PCP, and cannabis. Fingernail drug testing is extremely accurate and a positive test can be admitted as evidence in a court proceeding.
Depending on your metabolism and the rate at which your nails grow, the test can detect the presence of drugs in your system as far back as eight months. As nail grows in thickness and length, biomarkers build up in the nail at the germinal matrix and along the nail bed, collecting the full history of drug use
We use a non-intrusive, donor collected sample that has minimal impact on the donor's appearance.
