Hair analysis has emerged as an efficient method for detecting substance use. Hair retains a long-term record of alcohol and drug intake by capturing biomarkers within the hair's growing fibers. When obtained near the scalp, a hair sample can offer around a three-month detection period for alcohol and drugs. It is straightforward to gather, challenging to tamper with, and convenient to transport.
A 1.5-inch section comprising approximately 200 hair strands (roughly the diameter of a #2 pencil) nearest the scalp will yield 100mg of hair, which is considered the optimal amount for examination. For EtG, extra analyses, or tests exceeding 10 panels, a 150mg sample is suggested. It is advisable to measure the sample on a jeweler’s scale. In the absence of scalp hair, a comparable quantity of body hair can be collected. The term head hair refers exclusively to scalp hair. Body hair encompasses all other types, such as facial and axillary hair.
Process Overview
The primary stages in processing a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial incorporation of a specimen into the lab’s system, ensuring the sample was sealed and shipped correctly, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.
Screening involves a preliminary assessment for substances of abuse. Though Screening is an economical means to exclude drug usage in most samples, a positive screening result requires Validation to hold up in legal settings. Samples with a presumptive positive in Screening necessitate additional confirmation.
When a sample yields a presumptive positive during the Screening phase, more hair is extracted from the original sample and readied for Extraction. Here, drugs are extracted from the hair in a much lower concentration than in other methods (e.g., urine or oral fluid), which is why hair drug testing is one of the most complex methodologies to carry out.
Confirmation of any positive screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptive positive are cleaned before confirmation as required. The entire lab protocol from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly described as "hair follicle tests", the evaluation itself examines the hair strand rather than the follicle beneath the scalp.
