Hair Testing

Hair testing provides a much longer detection window of drug use, thus giving us a more complete drug use history that goes back as far as 90 days.  Hair testing offers the benefit of being a directly observed collection, with a specimen that is not easily adulterated.  Hair testing is useful for pre-employment and random drug testing.  With hair testing, a donors efforts to prepare for a drug test, either by stopping their drug use or cheating with adulterants or substitution, are not effective.
