Hair analysis has gained recognition as a potent resource for uncovering drug and alcohol consumption. Hair offers an enduring record of substance use by capturing biomarkers within the fibers of the hair as it grows. When collected near the scalp, hair can offer up to a three-month window for detecting alcohol and drugs. Hair is easy to collect, relatively resistant to tampering, and convenient to transport.
A sample measuring 1.5 inches, consisting of around 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp, equates to 100mg of hair, which is the preferred amount for analysis and verification. For EtG, additional tests, or panels exceeding 10, a specimen mass of 150mg is advised. It's suggested to measure the sample on a jeweler's scale. In the absence of scalp hair, an equivalent amount of body hair can be used. When we speak of head hair, we mean exclusively scalp hair. Body hair denotes all other hair varieties (e.g., facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test result comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary handling of a sample within a lab's system. This step includes ensuring the sample's proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody system.
Screening is a preliminary rapid assessment for drug abuse. Although Screening is an economical method to dismiss drug usage in most samples, a positive screen must be corroborated for legal acceptability. Any samples testing positive in Screening require further confirmation.
Should a sample prove positive in the Screening phase, additional hair is extracted from the original specimen and readied for Extraction. In this phase, drugs are extracted from hair at concentrations lower than those in alternative methods (such as urine or oral fluid), making hair drug analysis particularly challenging.
Confirmation of any positive screen result occurs through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are cleansed as needed. The complete laboratory process from Accessioning to Confirmation is monitored under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
