Recognized as an essential method for detecting drug and alcohol consumption, hair analysis captures long-term evidence of substances by embedding biomarkers within the hair’s fiber as it grows. A close-to-scalp sample effectively offers up to a 3-month timeframe for identifying drug and alcohol use. The collection process is straightforward, with a low risk of tampering, and the samples are easily transportable.
A section measuring 1.5 inches composed of approximately 200 hair strands (comparable to a #2 pencil in thickness) near the scalp provides a 100mg sample that is optimal for both screening and confirmation procedures. For tests such as EtG or those above 10 panels, a 150mg quantity is advisable. Using a jeweler’s scale to weigh the sample is recommended. In cases where scalp hair is unavailable, an equivalent quantity of body hair can be used. References to head hair pertain solely to scalp hair, whereas body hair includes all other types (such as facial or axillary hair).
Process Overview:
The laboratory process for processing a drug test result encompasses four principal phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the preliminary integration of a sample into a lab’s system. It involves ensuring the sample’s secure sealing and proper shipping, assigning a random LAN (Laboratory Accessioning Number), and updating any missing data absent in an electronic chain of custody system.
The Screening phase entails an initial rapid assessment for substances of abuse. While efficient for excluding drug use in most cases, any positive screen must be confirmed to be legally credible. Samples showing a presumptive positive in Screening must undergo a follow-up confirmation.
When cases indicate a presumptive positive during Screening, additional hair is taken from the initial sample and readied for Extraction. The extraction process retrieves drugs from hair at notably lower concentrations than other techniques (such as urine or oral fluid), thus making hair testing the most challenging methodology.
Confirmation of any positive screening outcome utilizes methods such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleaned prior to confirmation when necessary. The comprehensive laboratory operation from Accessioning through Confirmation is subject to review under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.
