Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. Hair retains a prolonged account of alcohol and drug intake, capturing biomarkers within the strands' fibers as they grow. When taken near the scalp, hair can offer up to a 3-month period for detecting alcohol and other substances. Collection of hair is straightforward, somewhat resistant to tampering, and convenient for transport.
A 1.5-inch segment consisting of roughly 200 hairs (comparable in size to a #2 pencil) nearest the scalp yields 100mg of hair, which is considered the perfect sample size for screening and confirmation. For EtG, supplementary, and/or tests exceeding 10 panels, a sample of 150mg is advised. It is recommended to measure the sample using a jeweler’s scale. In cases where scalp hair is not present, a comparable quantity of body hair can be collected. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The four principal stages in the laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial inputting of a sample into the laboratory’s system. This process includes validating that the sample was appropriately sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and finalizing any additional data entry that an electronic chain of custody system does not cover.
Screening entails a preliminary evaluation for substances of abuse. While Screening provides a cost-efficient method to exclude drug use for most samples, a positive screen necessitates confirmation to be court-admissible. Any samples that test as presumptively positive during Screening require a secondary validation.
Should a sample be deemed presumptively positive during the Screening phase, additional hair is extracted from the original sample and prepared for Extraction. At this phase, substances are drawn out from hair at a significantly lower concentration than other methods (such as urine or oral fluid), highlighting why hair drug screening is considered the most complex methodology.
Confirmation of any positive screening result is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation as necessary. The full laboratory sequence from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and is accredited to ISO/IEC 17025 standards.
