Hair analysis has gained recognition as an effective method for detecting the use of drugs and alcohol. Hair serves as a long-term record of alcohol and drug exposure by embedding biomarkers within the fiber structure of the developing hair strand. When cut near the scalp, hair offers a detection timeline extending up to around 3 months for both alcohol and drugs. Its collection is straightforward, tampering is somewhat challenging, and it can be easily mailed.
A 1.5-inch section encompassing about 200 hairs (roughly equivalent to a #2 pencil's diameter) closest to the scalp yields 100mg of hair, which is ideal for both screening and validation. For tests involving EtG, additional panels, or more than 10 panels, a 150mg sample of the hair is advised. For accuracy, weighing the sample with a jeweler’s scale is suggested. If scalp hair is not accessible, an equivalent quantity of body hair may be used. By head hair, we specifically mean scalp hair. Body hair refers to any other hair types (e.g., facial, axillary).
Process Overview
The laboratory work involved in processing a drug test outcome involves four pivotal phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about the initial integration of a sample into a lab’s management system. This phase ensures the sample's seal and transport were correct, assigns an arbitrary LAN (Laboratory Accessioning Number), and finalizes any data input lacking in an electronic chain of custody system.
Screening is a preliminary rapid drug check. Though Screening is an economical means to exclude drug use in most specimens, a positive result necessitates validation for legal proceedings. Samples showing tentative positivity during Screening need secondary validation.
Should a sample demonstrate tentative positivity in Screening, additional hair is retrieved from the original sample for Extraction. Here, drug compounds are extracted from hair at concentrations lower than those used in alternative methodologies (e.g., urine or oral fluids), hence the greater challenge of hair drug analysis.
Verification of any positive screen result employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. All tentative positive samples undergo washing as needed before confirmation. The entire lab operation from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair guideline and ISO / IEC 17025 accreditation standards.
