Hair testing is highly regarded as a robust means to identify drug and alcohol usage. Hair strands capture biomarkers within their fibers, allowing for a long-term record of substance use. When collected near the scalp, hair can provide up to a three-month detection window for alcohol and drugs. It is easy to collect, tough to tamper with, and convenient to transport.
A sample of roughly 1.5 inches consisting of about 200 hair strands (similar to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is optimal for screening and confirmation. For EtG, additional tests, or panels beyond ten, a specimen of 150mg is advisable. Using a jeweler’s scale for weighing the sample is suggested. If scalp hair isn't available, an equivalent amount of body hair can be used. "Head hair" specifically refers to scalp hair only, while "body hair" includes all other types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result is broken down into four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into a laboratory’s system, verifying proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.
Screening acts as an initial assessment for the presence of abused drugs. It's a cost-efficient approach to exclude drug usage in most samples, but positive screenings require confirmation to be upheld in legal settings. Presumptive positives from Screening mandate secondary confirmation.
Upon a presumptive positive result in Screening, additional hair is extracted from the initial specimen for the Extraction phase. Drugs are retrieved from hair at lower concentrations than in other testing mediums (like urine or oral fluid), underscoring the complexity of hair drug screening.
Confirmation for any positive screening outcome employs GC/MS, GC/MS/MS, or LC/MS/MS. All samples considered presumptive positives are cleansed before confirmation if necessary. The entire laboratory process, from Accessioning through Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
