Hair analysis is increasingly seen as an effective method for detecting drug and alcohol consumption. The hair captures long-term data of substances by embedding biomarkers within its strands. Collecting hair near the scalp can offer up to an estimated 3-month detection period for alcohol and drugs. The collection process for hair is straightforward, tampering is somewhat challenging, and it is convenient to ship.
A sample of approximately 1.5 inches consisting of about 200 hair strands (equivalent to the diameter of a #2 pencil) taken from close to the scalp will yield 100mg of hair, which is the optimal amount for conducting screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg is the recommended sample size. We advise weighing the sample with a jeweler’s scale. If scalp hair cannot be obtained, a comparable amount of body hair can be used. References to head hair denote only scalp hair, while body hair includes all other types (such as facial and axillary).
Process Overview
The drug test result processing in a laboratory involves Accessioning, Screening, Extraction, and Confirmation as the primary stages.
Accessioning is the first step where a sample is incorporated into a laboratory’s system. It entails confirming the sample's proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and inputting any additional data absent from an electronic chain of custody system.
During Screening, a preliminary rapid test is performed to check for drug abuse. Although Screening is a cost-efficient mode to eliminate drug usage in a majority of samples, a positive result must be corroborated for legal admissibility. Samples deemed presumptively positive during Screening mandate further confirmation.
When a sample indicates a presumptive positive at the Screening level, additional hair from the original sample is set aside for Extraction. This phase involves retrieving drugs from hair at much lower concentrations than found in other methods like urine or oral fluid, establishing hair drug testing as the most complex methodology.
Confirmation of any positive Screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples with presumptive positive results undergo washing before confirmation when necessary. The entire procedure from Accessioning to Confirmation is scrutinized under the guidance of both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Note: Frequently referred to as "hair follicle tests", the examination is actually conducted on the hair strand, not the follicle beneath the scalp.
