Hair analysis is increasingly recognized as an effective means for identifying drug and alcohol consumption. It offers a prolonged overview of substance use by incorporating biomarkers throughout the hair as it grows. When hair samples are taken from near the scalp, they can reveal drug or alcohol intake history for up to about three months. The collection process is straightforward, and tampering is challenging, making transportation effortless.
To gather the ideal sample size for testing, a 1.5-inch segment consisting of approximately 200 hair strands close to the scalp can provide 100mg, which suffices for both screening and confirmation. For EtG, additional panels, or tests exceeding 10 panels, a sample of 150mg is suggested. It's advisable to measure the sample using a jeweler’s scale. If scalp hair isn't available, an equivalent quantity of body hair can be used. 'Head hair' refers specifically to scalp hair, while 'body hair' pertains to all other hair types (such as facial or axillary).
Process Overview
The laboratory workflow for a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is first logged into the laboratory's system. This step includes confirming the sample’s proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and recording any supplementary data not included by electronic means.
Screening is an initial rapid evaluation for illicit substances. Though Screening is a budget-friendly approach for excluding drug use in most samples, results showing positivity require confirmation for legal validity. Any Screening-positive samples need a subsequent confirmation.
For samples indicating presumptive positivity at the Screening phase, additional hair from the original sample is designated for Extraction. This stage involves isolating drugs from hair at a significantly lower concentration than other approaches (e.g., urine or saliva), which accounts for the complexity of hair drug analysis.
Positive screenings proceed to Confirmation using methods like GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptively positive samples undergo necessary washing. The full laboratory sequence from Accessioning to Confirmation is assessed according to both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
