Hair analysis is increasingly recognized as an effective means for identifying substance use involving alcohol and drugs. The fibers of a growing hair strand embed biomarkers that offer a chronological record of substance use. When sampled near the root, a strand can reveal drug and alcohol exposure over a period of up to 90 days. Collecting hair is straightforward, hard to tamper with, and convenient for transport.
Gathering a 1.5-inch cut of approximately 200 strands, comparable to the thickness of a #2 pencil, will yield 100mg, the optimal quantity for primary analysis and verification. For EtG, additional substances, or tests exceeding 10 substances, a specimen of 150mg is advisable. Utilizing a jeweler’s scale is recommended for accuracy. Should scalp hair be insufficient, a comparable measure of body hair is acceptable. "Head hair" references only scalp hair, whereas "body hair" encompasses all other types (such as facial or underarm).
Process Overview
The drug testing laboratory process encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning integrates a sample into the lab’s database. This process checks for proper sealing and shipping, allocates a unique LAN (Laboratory Accessioning Number), and finalizes any pending data outside of the electronic chain of custody system.
Screening serves as an initial evaluation for abuse substances. Although cost-efficient for dismissing drug presence in most samples, a positive screen must undergo confirmation to be valid for legal purposes. Presumptive positives from Screening necessitate a follow-up confirmation.
When a sample is flagged as presumptively positive during Screening, additional hair from the original collection is processed for Extraction. This step involves retrieving drugs from hair in concentrations lower than those in urine or saliva tests, contributing to the complexity of hair drug testing.
Confirmation for any positive findings during Screening is achieved via methods such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo washing before the confirmation phase as necessary. The complete lab procedure from Accessioning to Confirmation is subject to review under the CAP (College of American Pathologists) Hair protocol, alongside ISO / IEC 17025 accreditation.
