Hair testing is increasingly recognized as an effective method for identifying drug and alcohol use. Hair offers a detailed retrospective of substance consumption by capturing biomarkers within the hair's growing strand. When procured near the scalp, hair reveals a potential 3-month window for detecting alcohol and drugs. The process of collecting hair is straightforward, challenging to tamper with, and convenient to transport.
A sample of 1.5 inches comprising roughly 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal amount for analysis and confirmation. For EtG assessments, additional panels, or examinations beyond 10 panels, a quantity of 150mg is advised. It is best to weigh the hair on a jeweler's scale. If no scalp hair is available, an equivalent volume of body hair can be obtained. Note that "head hair" specifically refers to the scalp hair, while "body hair" encompasses all other types (such as facial or axillary hair).
Process Overview
The laboratory procedure for processing a drug test result includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning denotes the initial incorporation of a sample into the lab's system. The sample's proper sealing and shipment are verified, a random LAN (Laboratory Accessioning Number) is assigned, and any additional data entry not covered by an electronic custody system is completed.
Screening involves a preliminary rapid assessment for drug abuse. While cost-effective for eliminating drug usage in most cases, a positive screen necessitates confirmation for court admissibility. Any samples preliminarily positive in Screening require additional confirmation.
When a sample tests presumptively positive in Screening, further hair is extracted from the original specimen and readied for Extraction. During Extraction, drugs are isolated from hair at concentrations lower than other techniques (such as urine or oral fluid), which makes hair drug screening the toughest method to execute.
Confirmation for any positive result from Screening is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptively positive are washed as necessary before confirmation. The complete lab process from Accessioning through Confirmation is evaluated under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.
Advantages of hair drug testing:
Limitations:
Note: Commonly called "hair follicle tests", the analysis is conducted on the hair strand itself, not the hair follicle below the scalp.
