Hair analysis has gained recognition as an effective means for identifying drug and alcohol use. By capturing biomarkers within the fibers of the growing hair shaft, hair reveals a long-term history of alcohol and drug use. Hair collected near the scalp can offer a detection window of up to around 3 months for alcohol and drugs. The process of hair collection is straightforward, hard to tamper with, and convenient for shipping.
A sample measuring 1.5 inches, containing approximately 200 strands of hair (similar in size to a #2 pencil), near the scalp yields 100mg of hair, ideal for screening and confirmation. For tests including EtG, add-ons, or those exceeding 10 panels, 150mg of hair is suggested. We advise using a jeweler’s scale for weighing the specimen. If scalp hair is not accessible, an equivalent amount of body hair may be used. References to head hair pertain exclusively to scalp hair, while body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The principal stages in the laboratory analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the initial integration of a sample into the laboratory’s system. This procedure verifies proper sealing and shipment of the sample, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any supplementary data entry absent in an electronic chain-of-custody system.
Screening is a preliminary check for drug abuse. Although cost-effective for excluding drug usage in the bulk of samples, a positive screening outcome necessitates confirmation for legal admissibility. Samples that test presumptive positive during Screening require a secondary confirmation.
If Screening identifies a sample as presumptive positive, additional hair is extracted from the original specimen for the Extraction phase. At this stage, drugs are drawn from hair in much lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug analysis the most challenging technique to execute.
Confirmation of any positive screening outcome is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS. Presumed positive samples undergo washing as needed until confirmation. The entirety of the laboratory procedure from Accessioning through Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and holds accreditation to ISO / IEC 17025 norms.
