How does Hair Testing compare to urinalysis?
The primary differences are
1) wider window of detection
2) inability to tamper with the test
Cocaine, methamphetamine, opiates and PCP are rapidly excreted and usually undetectable in urine 72 hours after use. The detection period for hair is limited only by the length of the hair sample and is approximately 90 days for a standard test.
At this time there are no known adulterants for hair tests. Since hair tests analyze the drugs inside the hairshaft, external contaminants/chemicals have no effect.
Additional advantages include non-intrusive collection procedures, virtual
elimination of test evasion.
The combination of an increased window of detection and resistance to evasion makes Hair Testing far more effective than urinalysis in correctly identifying drug users.
