Hair analysis is recognized as an effective means for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drugs by embedding biomarkers within its fibers as it grows. When collected near the scalp, hair can offer roughly a 90-day detection period for alcohol and drugs. The collection process is straightforward, with little risk of tampering, and shipping is uncomplicated.
A sample of approximately 1.5 inches containing around 200 hair strands (akin to the diameter of a #2 pencil) nearest to the scalp offers 100mg, which is optimal for screening and confirmation. For EtG or tests exceeding 10 panels, 150mg of the sample is advisable. It is suggested to weigh the sample using a jeweler’s scale. In the absence of scalp hair, a similar quantity of body hair may be used. The term "head hair" pertains exclusively to scalp hair, whereas "body hair" encompasses other types (facial, axillary, etc.).
Process Overview
The key stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the initial integration of a sample into a lab’s system. This step includes ensuring the sample was correctly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any outstanding data entries absent from an electronic chain of custody system.
Screening offers an initial quick assessment for drugs of abuse. Screening is a cost-effective measure to dismiss drug use for most samples; however, a positive indication in Screening must be validated for legal admissibility. Samples that test presumptively positive in Screening must undergo secondary validation.
For samples testing presumptively positive at the Screening phase, further hair is extracted from the initial specimen and prepped for Extraction. Here, drugs are isolated from hair at concentrations significantly lower than in other methods (e.g., urine or oral fluid), making hair drug screening among the most challenging methodologies to execute.
Positive results from the Screening process undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Any samples with presumptive positives are washed before Confirmation if necessary. The comprehensive lab process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair classification and is also certified to the ISO / IEC 17025 standards.
