Q: Is testing very accurate?
Will the results come back
positive if my child is not
taking drugs, but has been in
contact with drug users?
A: The Psychemedics PDT-90® hair follicle tests uses one of
the most effective hair follicle tests on the market, the same patented technology relied upon
by corporations nationwide. Hair samples are purified to remove any external
contaminants.
As with any drug testing, cutoff levels are utilized to help ensure that inadvertant or unintentional contact with drugs will not create a false positive result. The testing technology is designed to show the presence of drug levels which would only be consistent with the ingestion of drugs such as cocaine, meth, marijauna, heroin, ecstasy, pcp, crack, thc, and opiates.
All samples are tested using a radioimmunoassay screen. Before any positive test result is reported, the sample is subjected to a second, confirmatory test using gas chromatography/mass spectrometry (GC/MS), considered the gold standard for forensic drug testing.
Q: How does
PDT-90® hair follicle tests compare with urinalysis tests currently on the
market?
A: Urinalysis can only check to see if drugs were used within the previous
2-3 day period for most drugs. PDT-90® hair follicle testing can check for drug use within a
90-day period. This makes it harder for a child to evade detection.
Ways of beating urine tests are widely known by teens. They can tamper with the specimen, flush their systems with water, and even purchase clean urine to substitute for their own. However, the easiest way for them to beat a urine test is just not to use for 3 days. In addition, PDT-90® follicle testing should be less embarrassing to you and your child than urinalysis, since collection and handling is clean and easy.
