Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair retains biomarkers within the fibrous structure of the growing strands, offering a prolonged timeline of drug and alcohol history. Hair collected near the scalp can reveal a detection period of up to roughly 90 days for substances; it is straightforward to gather, relatively tamper-resistant, and simple to send.
A strand section of 1.5 inches comprising roughly 200 hairs (equivalent in thickness to a #2 pencil) situated closest to the scalp provides 100mg of hair, which is the preferred amount for testing and validation. For EtG, additional examinations, and/or analyses beyond ten panels, a 150mg specimen is advised. It is suggested to use a jeweler’s scale for specimen weighing. In the absence of scalp hair, an equivalent sample of body hair may be used. By head hair, we mean only scalp hair, while body hair covers all other types of hair (like facial, axillary, etc.).
Process Overview
The laboratory processing of drug tests encompasses four vital stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the primary integration of a sample into a lab's system, which includes validating that the sample is appropriately sealed and dispatched, generating a random LAN (Laboratory Accessioning Number), and finalizing any additional data input not facilitated by an electronic custody chain system.
Screening constitutes an initial rapid assessment for substance abuse. Although Screening economically dismisses drug usage in most samples, a positive result mandates confirmation to be legally acceptable. All samples showing presumptive positives during Screening require further corroboration.
Should a sample show a presumptive positive during Screening, additional hair is extracted from the original specimen for Extraction. In this step, drugs are drawn from hair at significantly lower concentrations than in alternative methodologies (like urine or oral fluid), establishing hair drug analysis as the most challenging method to execute.
Verification of positive Screening results is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives are cleansed before confirmation as necessary. The entire lab procedure from Accessioning to Confirmation undergoes scrutiny under both CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
