Hair analysis has increasingly become recognized as an effective means for detecting drug and alcohol consumption. The hair captures long-term evidence of these substances by entrapping biomarkers within its growing strands. When taken near the scalp, hair exhibits a detection timeframe of up to approximately three months for substances such as alcohol and drugs. Collection is straightforward, its alteration is somewhat challenging, and it can be shipped without complication.
A 1.5-inch portion comprising around 200 hair strands (approximately the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, the optimal sample size for initial and confirmatory tests. For EtG, additional tests, and/or those exceeding 10 panels, a volume of 150mg is advisable. It is advisable to weigh the hair sample using a jeweler’s scale. If scalp hair is unavailable, an equivalent quantity of body hair can be collected. In referring to head hair, only scalp hair is implied. Body hair refers to all other varieties (e.g., facial, axillary).
Process Overview
The laboratory assessment of a drug test result entails four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample into the laboratory system. This phase ensures the sample's sealing and shipping integrity, assigns a random LAN (Laboratory Accessioning Number), and completes additional data entry absent from an electronic chain custody system.
Screening performs an initial rapid analysis for drugs of misuse. Although a cost-efficient approach to dismiss drug usage in most samples, a positive screen necessitates verification for legal acceptance. Any samples indicative of a positive result during Screening necessitate further validation.
If Screening suggests a positive result, additional hair is extracted from the initial sample for the Extraction phase. This step extracts drugs from hair at lower concentrations compared to other samples (e.g., urine or oral fluid), making hair analysis among the most intricate methodologies.
Positive screening outcomes undergo Confirmation using methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed before confirmation if needed. The complete laboratory procedure from Accessioning through Confirmation adheres to the standards set by the CAP (College of American Pathologists) under the Hair designation and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: While commonly termed "hair follicle tests", the analysis pertains to the hair strand rather than the follicle beneath the scalp.
