The benefits of hair drug testing
Hair testing for drugs of abuse is the only drug testing method available that provides up to a 90-day drug use history. When compared with urine testing, hair testing provides nearly twice the number of positives due to its longer detection window. This makes hair testing from Quest an ideal solution for a number of drug testing programs.
Longer window of detection
Our hair testing detects nearly twice the number of positives as our urine test. Unlike urine drug testing, which may only detect drug use within the past 2-3 days, hair testing is able to detect a pattern of repetitive drug use for up to 90 days. While urine testing is well suited to detect recent drug use for post-accident or reasonable suspicion testing, a hair test is the most effective way to evaluate long-term patterns of use, making it an excellent option for a pre-employment or random testing program.
Convenient, tamper-resistant collections
Hair testing requires a small sample of hair that is collected under direct supervision without any invasion of privacy. Donors are typically sent to one of thousands of collection sites in our network equipped and trained for hair testing. 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.
Fast, reliable results
Our dependable turnaround times drive timely hiring decisions. Hair samples are sent by overnight delivery and are typically tested on the day they arrive at our laboratory. Negative results are often released within 24 hours. Non-negative screens undergo confirmatory testing and are typically released within an additional 24-72 hours.
Drug abuse in the workplace puts employers at a risk for higher insurance costs, increased accidents, more absenteeism and lower productivity. Hair testing, like all drug testing methodologies, helps to mitigate these risks by screening out applicants and employees who use drugs.
