Hair testing is recognized as an effective means for detecting drug and alcohol consumption. Hair can capture a historical record of alcohol and drug use, as biomarkers are retained in the hair shaft’s fibers as it grows. If harvested near the scalp, hair offers a detection timeframe of up to about 3 months for alcohol and substances. It is straightforward to collect, relatively challenging to tamper with, and easy to transport.
A sample measuring 1.5 inches from around 200 hair strands (roughly equivalent to a #2 pencil) nearest to the scalp results in 100mg, the recommended amount for both initial and confirmatory tests. For EtG, additional tests, and/or panels beyond ten, 150mg is advised. It's best to use a jeweler’s scale to weigh the sample. When scalp hair isn't accessible, an equivalent amount of body hair can be used. Head hair refers only to scalp hair, while body hair includes other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning processes a sample into a lab’s system. This step confirms the sample is sealed and transported correctly, assigns it a Laboratory Accessioning Number (LAN), and completes necessary data entry not covered by an electronic chain of custody system.
Screening performs a quick assessment for any drugs of abuse. While it’s a cost-effective method for excluding drug use in most samples, a positive screen must be confirmed to be legally valid. Samples that test presumptively positive in Screening need a secondary confirmation.
If the Screening stage returns a presumptive positive, additional hair from the primary sample is used for Extraction. Here, drugs are extracted from hair at lower concentrations than other methods (such as urine or oral fluid), making hair drug screening particularly challenging.
GC/MS, GC/MS/MS or LC/MS/MS is employed to confirm any positive screening outcome. All potential positive samples undergo a washing process before confirmation if necessary. The entire lab procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
