Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair offers an extended timeline of substance use by capturing biomarkers within the strands of developing hair. When retrieved near the scalp, hair can offer up to a roughly 3-month detection period for alcohol and other substances. Hair collection is straightforward, relatively tamper-resistant, and convenient for shipping.
A recommended sample size of 1.5 inches with approximately 200 hair strands (similar to a #2 pencil) nearest to the scalp will provide 100mg of hair, which is an optimal amount for testing and validation. For EtG, additional tests, or panels exceeding 10, a specimen of 150mg is advised. Using a jeweler’s scale is suggested for measuring the specimen. If scalp hair cannot be obtained, a comparable quantity of body hair can be used. Referring to head hair implies specifically scalp hair. Body hair covers all other types (facial, axillary, etc.).
Process Overview
The drug testing laboratory process involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning focuses on the initial integration of a sample into a laboratory’s system. It involves ensuring the sample’s seal and shipping were correct, allocating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent from an electronic chain of custody system.
Screening provides a rapid assessment for drugs of abuse. While it serves as a cost-effective method to exclude drug usage for most samples, a positive screen necessitates confirmation for legal acceptance. Presumptive positive samples in Screening indeed require further confirmation.
For a sample with a presumptive positive screening, additional hair is taken from the original specimen and prepared for Extraction. In this phase, drugs are drawn from hair at much lower concentrations compared to other strategies (for instance, urine or oral fluid), making hair drug screening the most challenging method to execute.
Confirmation for any positive screen result is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptively positive are cleaned prior to confirmation as needed. The entire laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair certification and compliance with ISO / IEC 17025 standards.
