Hair testing is recognized as a formidable means for identifying drug and alcohol consumption. Hair offers a prolonged timeline of alcohol and drug usage by capturing biomarkers within the fibers of the hair as it grows. When acquired near the scalp, hair can reveal usage within an estimated three-month period for alcohol and drugs. Gathering hair is straightforward, relatively challenging to tamper with, and uncomplicated to transport.
A sample measuring 1.5 inches with roughly 200 strands (comparable to a #2 pencil's thickness) nearest to the scalp will yield 100mg, which is optimal for both screening and confirmation. For EtG, additional tests, or analyses exceeding 10 panels, a sample of 150mg is advisable. Utilizing a jeweler's scale for measuring the sample is recommended. Should scalp hair be unavailable, a similar quantity of body hair is acceptable. References to head hair pertain solely to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning denotes the initial incorporation of a sample into the laboratory's system, ensuring proper sealing and shipping, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any supplementary data entry not included by an electronic chain of custody system.
Screening facilitates a preliminary rapid assessment for substances of abuse. Even though Screening effectively eliminates drug usage in most samples at a lower cost, a positive finding necessitates verification for potential court use, necessitating a secondary Confirmation for presumptive positive samples.
When a sample tests presumptively positive during Screening, additional hair is extracted from the initial sample for the Extraction phase. In this stage, drugs are extracted from hair at concentrations significantly lower than those used in alternative methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.
Verification of any positive screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results undergo cleansing before Confirmation as necessary. The comprehensive lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and the qualification to ISO / IEC 17025 standards.
