Hair analysis is now recognized as a potent method for identifying drug and alcohol consumption. It captures a comprehensive record of substance intake by embedding biomarkers within the hair's extending strands. When taken from near the scalp, hair can reveal substance usage information spanning up to around three months. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch section of around 200 hair strands (roughly equivalent to a #2 pencil's girth) nearest to the scalp yields 100mg, offering the optimal quantity for testing. For EtG, additional tests, and those exceeding 10 panels, a sample of 150mg is suggested. Using a jeweler’s scale to weigh the sample is recommended. In the absence of scalp hair, an equivalent volume of body hair can be used. Note that when referencing head hair, we mean scalp hair exclusively. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The critical stages in the laboratory analysis of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial stage of entering a sample into a lab’s system. This phase includes ensuring the sample's proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data input absent in an electronic chain of custody system.
Screening is a preliminary rapid examination for drug abuse. Although Screening offers a budget-friendly approach to eliminating drug usage in most samples, a confirmed positive screen is essential for court admissibility. Samples showing presumptive positivity in Screening necessitate further confirmation.
Should a sample be presumptively positive in Screening, additional hair is retrieved from the original sample for Extraction. This step involves isolating drugs from hair at a notably lower level than other techniques (e.g., urine or oral fluid), which accounts for the complexity of performing hair drug screening.
Verification of any positive screening finding is implemented using GC/MS, GC/MS/MS, or LC/MS/MS. Samples presumed positive are washed before confirmation as necessary. The comprehensive lab procedure from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair designation and the accreditation of ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: While frequently termed as "hair follicle tests", the analysis actually examines the hair strand rather than the sub-scalp follicle itself.
