Hair analysis is now recognized as a robust diagnostic approach for identifying drug and alcohol consumption. The fibers within hair strands capture biomarkers, providing a comprehensive overview of usage over time. Taking a sample near the scalp offers an insight into drug and alcohol presence within roughly a three-month period. Collecting samples is straightforward, tampering is challenging, and transportation is uncomplicated.
A 1.5-inch hair sample, roughly the size of a #2 pencil, containing around 200 strands or 100mg of hair, constitutes the optimal quantity for both initial and confirmatory testing. For EtG, additional evaluations, or tests exceeding 10 panels, a 150mg sample is suggested. It is advised to measure the sample's weight using a jeweler’s scale. In instances where scalp hair is absent, a comparable amount of body hair may be taken. When we mention head hair, we specifically mean scalp hair, whereas body hair encompasses all other types (such as facial and axillary hair).
Process Overview
The laboratory process for drug testing comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial stage where samples are integrated into a lab's system. This process includes checking the sample's seal and shipment accuracy, generating a unique LAN (Laboratory Accessioning Number), and fulfilling any extra data entries that an electronic chain of custody might lack.
Screening provides a preliminary analysis to identify drugs of abuse. While it offers a cost-efficient method to dismiss drug use in most cases, a positive Screening result requires further validation to be legally admissible. Hence, samples showing a positive presumption during Screening must undergo subsequent verification.
Should a sample yield a positive presumption in the Screening phase, the next step is to extract more hair from the initial sample for Extraction. This phase involves extracting drugs from hair at markedly lower concentrations compared to other methods like urine or oral fluid testing. As such, hair drug analysis is acknowledged as the most complex method to execute.
Confirmation of any positive result obtained during Screening is facilitated by GC/MS, GC/MS/MS, or LC/MS/MS techniques. Prior to confirmation, all samples showing presumptive positives undergo a washing process as needed. This comprehensive laboratory methodology, from Accessioning through Confirmation, is subject to review in accordance with CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although often termed "hair follicle tests", the analysis is actually conducted on the hair strand itself, not the hair follicle beneath the scalp.
