Hair testing is widely recognized as an effective method for identifying drug and alcohol use. Hair retains a historical record of drug and alcohol consumption by assimilating biomarkers within the fibers of the hair shaft as it grows. When harvested near the scalp, hair can reveal a detection period of up to three months, measuring exposure to alcohol and other drugs. Hair collection is straightforward, relatively tamper-resistant, and convenient to transport.
A 1.5-inch length of around 200 hair strands (approximately equivalent to the girth of a #2 pencil) near the scalp yields 100mg of hair, which is optimal for screening and verification. For EtG, additional specificity, or testing exceeding 10 panels, 150mg of the sample is advised. We suggest measuring the sample using a jeweler's scale. Should scalp hair not be obtainable, a comparable quantity of body hair might be used. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses other types (facial, axillary, etc.).
Overview of the Process
The laboratory assessment of a drug test outcome involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning comprises the preliminary handling of a sample within the laboratory's framework. This step involves ensuring the sample's proper sealing and dispatch, generating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data input absent from an electronic chain of custody system.
Screening offers an initial assessment for potential drug presence. While cost-efficient for excluding drug usage in most samples, positive results in Screening require confirmation to be legally enforceable. Any samples that test positive presumptively in Screening must undergo further verification.
If a sample tests positive presumptively during Screening, additional hair is extracted from the initial sample and readied for Extraction. This procedure extracts drugs from hair at notably lower concentrations than alternative techniques (such as urine or oral fluid), rendering hair drug screening the most intricate method to execute.
Verification of any positive Screening outcome is finalized using GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positive samples are cleansed before Confirmation if necessary. The complete laboratory sequence from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 criteria.
