Hair analysis is now recognized as an effective means for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drugs by embedding biomarkers within the fibers of the hair as it grows. When cut near the scalp, hair can present up to a roughly 90-day detection span for alcohol and drugs. The sampling of hair is straightforward, relatively tamper-proof, and simple to transport.
A sample measuring 1.5 inches consisting of approximately 200 strands (roughly equivalent to the thickness of a #2 pencil) closest to the scalp will provide 100mg, which is the optimal amount for both screening and verification. For tests including EtG, additional categories, and/or those exceeding 10 panels, a specimen of 150mg is advised. It's advisable to measure the specimen using a jeweler's scale. If scalp hair cannot be obtained, an equivalent quantity of body hair may be taken. When mentioning head hair, it refers exclusively to scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).
Process Overview
The drug testing laboratory procedure consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the first phase of sample processing within the lab system. This includes checking that the sample was properly secured and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any remaining data entry that might not be covered by an electronic chain of custody system.
Screening is an initial rapid assessment for drugs of abuse. While Screening is an economical method to exclude drug usage for the majority of samples, a screen yielding a positive result requires confirmation to hold up in court. Any samples indicating a positive result in Screening necessitate a secondary validation.
Should a sample appear positive during the Screening phase, extra hair is removed from the primary specimen and set for Extraction. During this stage, drugs are extracted from the hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging approach to execute.
Verification of a positive screening outcome is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples indicating a presumptive positive are cleansed prior to confirmation as required. The complete laboratory sequence from Accessioning to Confirmation is scrutinized in line with the CAP (College of American Pathologists) Hair criteria and the accreditation to ISO / IEC 17025 standards.
