Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair archives a prolonged history of alcohol and other substances by embedding biomarkers within the strands of growing hair. When retrieved near the scalp, hair can reveal up to a 3-month detection span for alcohol and other substances. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches consisting of approximately 200 hair strands (roughly the diameter of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample size for analysis and verification. For EtG, additional analyses, and/or tests beyond 10 panels, a specimen of 150mg is advised. It's recommended to weigh the specimen using a jeweler’s scale. Should scalp hair be unavailable, an equivalent amount of body hair can be gathered. When referencing head hair, we specifically mean scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The laboratory examination of a drug test result consists of four core steps: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the initial handling of a sample involves entry into a lab’s system. This process includes confirming the sample's proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any remaining data input not covered by an electronic chain of custody.
Screening performs a preliminary check for illegal substances. While Screening is an economical method to eliminate drug usage in most samples, any positive results need confirmation to be valid in legal settings. All samples that test presumptively positive in Screening necessitate secondary affirmation.
Should a sample test presumptively positive at the Screening stage, additional hair is extracted from the original specimen and readied for Extraction. During this phase, drugs are isolated from hair at significantly lower concentrations than those found in other techniques (such as urine or saliva), making hair drug analysis the most challenging technique to execute.
GC/MS, GC/MS/MS, or LC/MS/MS is employed for the Confirmation of any positive screening outcome. All samples with presumptive positives are cleansed prior to confirmation as per requirements. The complete laboratory process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
