Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. Hair serves as an archival record of alcohol and illicit substances by embedding biomarkers within the strands' fibers. When obtained near the scalp, hair can reveal up to a 90-day window of detection for alcohol and other substances. Hair is straightforward to collect, relatively tamper-resistant, and convenient to transport.
A 1.5-inch hair sample comprising about 200 strands (roughly the thickness of a #2 pencil) nearest the scalp provides 100mg of hair, which is the optimal amount for assessment and verification. For EtG, additional tests, and/or panels exceeding 10, 150mg of the hair is suggested. We advise using a jeweler’s scale for measuring the sample. Should scalp hair be inaccessible, an equivalent volume of body hair can be utilized. When mentioning head hair, we specifically refer to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The key stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of incorporating a sample into a laboratory's system. This step involves confirming the sample was correctly sealed and transported, generating a random LAN (Laboratory Accessioning Number), and finishing any supplemental data entry omitted by an electronic custody chain.
Screening consists of a preliminary swift assessment for drugs of abuse. While Screening offers a cost-efficient method to negate drug usage in the majority of samples, a positive result requires confirmation to be admissible legally. Samples that test presumptively positive during Screening necessitate secondary confirmation.
Should a sample test positive at the Screening phase, more hair is retrieved from the original specimen and readied for Extraction. This phase involves drug extraction from hair at significantly lower concentrations than other methods (e.g., urine or oral fluids), highlighting the complexity of hair drug screening.
Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive are cleansed before confirmation if necessary. The complete laboratory sequence from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and accreditation compliant with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Despite being often called "hair follicle tests," the test itself concentrates on the hair strand, not the hair follicle beneath the scalp.
