Hair Follicle Testing

Hair follicle testing is the most commonly used method for detecting the presence of drug abuse over a wide range of time, it is highly reliable and accurate. Hair testing has been proven as acceptable evidence in court systems around the world; and because the inner shaft is what is analysed, it cannot be adulterated by hair dye bleach or other products.

Although hair follicle testing cannot identify current impairment, it is effective in identifying historical drug use. It takes approximately 5-10 days from the time of initial drug use for the hair containing the drug to grow above the scalp. At this point, the hair can be collected. SureHire sends all hair collections to Psychemedics, the only hair testing laboratory that is approved by the Standards Council of Canada.

Lab Analysis 

The method used for the detection of drug use in the hair is, immunoassay and GC/MS/MS or LC/MS/MS confirmation which measures the drug molecules and metabolites entrapped in the hair that formed, following ingestion.

The lab results will be reviewed by a Medical Review Officer (MRO) who is a licensed physician responsible for evaluating drug testing. If a result is positive, the MRO will contact the candidate to determine whether the result was based on valid prescription use or not.
