Hair analysis is regarded as an effective approach for identifying drug and alcohol consumption. Hair captures a chronic record of drugs and alcohol via embedding biomarkers in the strands of growing hair. When taken from near the scalp, hair can reveal a detection timeline of up to roughly 3 months for alcohol and substance identification. Collecting hair is straightforward, challenging to tamper with, and simple to transport.
Acquiring a 1.5-inch section of about 200 hair strands (comparable to a #2 pencil's width) nearest to the scalp yields 100mg of hair, the optimal sample size for analyzing and verification. For EtG, add-ons, and/or examinations exceeding 10 panels, a 150mg specimen is advised. Measuring the specimen with a jeweler’s scale is recommended. If scalp hair is unobtainable, a proportionate amount of body hair might be acquired. Referring to head hair implies scalp hair exclusively. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The critical phases in laboratory handling of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary activity of entering a sample into a lab's system. This process involves confirming that the sample was duly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any requisite data input not furnished by an electronic chain of custody mechanism.
Screening entails an initial rapid assessment for illicit drugs. Screening is an economical method for ruling out drug usage in most samples; however, a positive screen must be authenticated to be legally viable. Samples that appear positive in Screening demand further confirmation.
Should a sample appear positive during Screening, additional hair is extracted from the primary sample and prepared for Extraction. During this phase, drugs are drawn from hair at significantly lower concentrations compared to other methods (ex. urine or oral fluid), making hair drug tests meticulously complex to conduct.
Verification of any positive Screening finding is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples are cleansed prior to confirmation as deemed necessary. The complete lab procedure from Accessioning through Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and adherence to ISO / IEC 17025 standards.
