Hair drug test collections from trained professionals

Collector cuts a hair drug test sample at PSC

Hair drug testing requires a small sample of hair that is collected under direct supervision without any invasion of privacy. During a hair collection, the collector cuts approximately 100-120 strands of hair from the crown of the donor’s head. The hair is cut as close to the scalp as possible, so only the strands of hair above the scalp are tested and not the actual hair follicle (the pocket below the scalp from which the hair strand grows). This makes hair testing a tamper-resistant, observed drug screening method.

Collection sites in our network have gone through our online training and specimen collection certification. These sites also maintain hair collection supplies on-site, meaning your donors simply need to show up and provide their hair sample. Use our online collection site locator to search for the hair testing site most convenient for your donor.

Our network of hair collection sites contains approximately 2,000 locations across the country, with additional locations around the globe. Our collection sites deliver a convenient, consistent and professional experience that reduces employee downtime and improves donor satisfaction.
