Recently, hair follicle drug testing has gained popularity over other methods. Many organizations, such as employers, courts, and substance abuse experts, prefer hair testing over the typical urine test. This method is particularly favored by employers with zero-tolerance policies, judicial systems, and probationary individuals. The primary advantage of hair testing is its extended drug detection period, up to 90 days, carried out in a monitored environment and nearly impossible to tamper with. However, for detecting recent substance use within the last 5 days, urine tests are still considered most precise.

Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. Hair retains evidence of alcohol and drug use within the fibers of the hair shaft, providing a lengthy history of substance intake. When collected near the scalp, hair offers approximately a 3-month detection period for alcohol and drugs. Collection is straightforward, manipulation is challenging, and transport is uncomplicated.
A 1.5-inch hair sample comprising approximately 200 strands (similar in size to a #2 pencil) positioned nearest the scalp yields 100mg, which is an optimal sample size for both screening and confirmation. For EtG, additional tests, or panels exceeding 10, 150mg of the sample is advisable. It's advisable to weigh the sample using a jeweler’s scale. In cases where scalp hair is unavailable, a comparable amount of body hair is suitable. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other varieties (facial, axillary, etc.).
Process Overview
The core steps in lab drug test processing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the sample's initial processing within a lab’s setup, ensuring proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any additional data entry absent from an electronic chain of custody system.
Screening performs a preliminary check for abuse substances. While cost-effective for ruling out drug use in most samples, a positive screen requires confirmation to be legally valid. Presumptively positive samples in Screening necessitate further confirmation.
For samples with presumptive positives in Screening, additional hair is extracted from the original sample and prepped for Extraction. Here, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), thus making hair drug screening the most intricate method to execute.
Confirmation of any positive screen result employs GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed pre-confirmation as necessary. The complete lab process, from Accessioning to Confirmation, undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
