Hair analysis is now regarded as an effective means for identifying drug and alcohol consumption. Hair captures a long-term record of substances by encapsulating biomarkers within the fibers of developing hair strands. When taken near the scalp, hair can offer a detection period of up to roughly 3 months for various substances. Hair is easy to collect, somewhat resistant to tampering, and simple to transport.
A 1.5-inch section of approximately 200 hairs (roughly the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the preferred amount for both screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, 150mg is advised. Ensure the specimen is weighed using a jeweler's scale. If scalp hair is not available, a similar quantity of body hair can be obtained. "Head hair" refers solely to scalp hair, whereas "body hair" includes all other types (such as facial, axillary, etc.).
Process Overview
The four primary stages in lab processing of drug test outcomes are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial management of a sample within a lab's system. This process verifies that the sample was properly sealed and delivered, assigns a random LAN (Laboratory Accessioning Number), and involves any additional data input not supplied by an electronic chain of custody system.
Screening executes a swift preliminary assessment for substances of abuse. Although Screening is an economical process to exclude drug use in the majority of samples, a positive result necessitates confirmation for courtroom acceptability. All samples that test presumptively positive during Screening require further validation.
When a sample tests presumptively positive during Screening, additional hair is extracted from the original specimen for preparation in the Extraction phase. Here, substances are extracted from hair at lower concentrations compared to other methods (such as urine or oral fluid), highlighting the complexities of hair drug screening.
For any positive Screening outcome, Confirmation is performed using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All presumptive positive samples undergo washing prior to Confirmation as appropriate. The complete lab process from Accessioning to Confirmation is inspected under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
