Hair testing is increasingly
becoming the testing technology of choice for many corporate drug-testing
programs. Studies comparing positivity rates in hair versus urine indicate
that employers can detect nearly twice as many drug users before they are
employed. For some drug categories the positive hit rate is much higher. Some
additional advantages of hair testing over urinalysis include an increased
window of detection and increased likelihood of specimen availability for
retest. |
