Hair analysis has emerged as an effective means for identifying consumption of drugs and alcohol. Hair offers a prolonged retrospective view of substance use by securing biomarkers within the strands' fibers as they grow. When hairs are gathered near the scalp, they may deliver a detection period of up to roughly 90 days for alcohol and drugs. The process of hair collection is straightforward, moderately resistant to tampering, and convenient for shipping.
A hair sample of 1.5 inches, consisting of approximately 200 strands (around the thickness of a #2 pencil) nearest to the scalp, supplies 100mg of hair, which is optimal for both screening and confirmation. For tests like EtG, or those exceeding 10 panels, 150mg of the sample is advisable. The sample should be weighed using a jeweler's scale. Should scalp hair not be obtainable, an equivalent volume of body hair is an alternative. "Head hair" refers strictly to scalp hair, while "body hair" encompasses all other types (like facial or axillary hair).
Process Overview
The primary steps in the laboratory analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the lab’s database. This step confirms proper sealing and shipment of the sample, assigns a random Laboratory Accessioning Number (LAN), and completes any pending data entry omitted by an electronic chain of custody system.
Screening offers an initial rapid evaluation for substances of abuse. Though Screening is an economical approach to exclude drug presence in most samples, any positive result necessitates a confirmatory test to be legally credible. Any samples that yield a presumptive positive outcome in Screening need a subsequent confirmation.
Should a sample test presumptive positive during Screening, additional hair is extracted from the initial sample and prepped for Extraction. At this point, drugs are isolated from hair at significantly lower levels than in other methods (e.g., urine or oral fluid), underscoring why hair analysis is the most challenging method to conduct.
Verification of any positive findings from screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples with presumptive positive results are cleansed before confirmation if necessary. The full laboratory procedure from Accessioning to Confirmation is monitored under both the College of American Pathologists (CAP) Hair designation and ISO / IEC 17025 accreditation standards.
