Hair analysis is regarded as an effective method for detecting drug and alcohol consumption. Hair strands capture historical data of alcohol and drugs by encasing biomarkers within the hair's structure as it grows. When taken near the scalp, hair can reveal a detection window of up to 3 months for alcohol and substances. Hair sampling is straightforward, relatively tamper-resistant, and easily transportable.
A length of 1.5 inches of approximately 200 hair strands (around the width of a #2 pencil) from the scalp yields 100mg of hair, which is the optimal sample for both screening and confirmation purposes. For comprehensive EtG, extra tests, and/or analyses exceeding 10 panels, a sample of 150mg is suggested. It is advisable to weigh the specimen using a jeweler’s scale. In the absence of scalp hair, a comparable quantity of body hair may be utilized. "Head hair" specifically denotes scalp hair. "Body hair" encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The four principal stages in laboratory drug test processing are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial sample processing within a laboratory’s infrastructure. This process checks if the sample is properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data input not covered by an electronic chain of custody system.
Screening is an initial rapid assessment for drugs of abuse. While Screening efficiently eliminates drug use in most samples, a positive result must be confirmed for legal admissibility. Samples showing presumptive positivity during Screening must undergo secondary confirmation.
In cases of presumptive positivity during Screening, more hair is drawn from the initial sample for Extraction. At this stage, drugs are removed from the hair at lower concentrations compared to other techniques (e.g., urine or oral fluid), making hair drug testing one of the most challenging methodologies to execute.
Positive Screening results are verified through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positivity undergo washing before confirmation as required. The entire laboratory sequence from Accessioning to Confirmation is scrutinized under the guidelines of the CAP (College of American Pathologists) Hair designation and aligns with ISO / IEC 17025 accreditation standards.
