Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair can capture biomarkers in the strands, offering a long-term record of substance use. When collected near the scalp, hair can reveal drug and alcohol consumption over a period of up to three months. Hair collection is straightforward, difficult to tamper with, and easy to transport.
A 1.5-inch hair sample, containing about 200 strands, roughly the width of a #2 pencil, equates to 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, or panels over 10, a 150mg sample is advised. Using a jeweler’s scale is a good practice for weighing the specimen. If scalp hair cannot be obtained, an equivalent amount of body hair may be used. For head hair, the reference is specifically to scalp hair, while body hair encompasses all other types (e.g., facial, axillary).
Process Overview
The laboratory processing of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves incorporating a sample into a lab’s system, which includes ensuring that it was sealed and shipped correctly, issuing a random LAN (Laboratory Accessioning Number), and entering any additional data not captured by an electronic chain of custody.
Screening provides an initial assessment for drugs of abuse. Though Screening is cost-effective for ruling out drug use in most cases, positive results require confirmation to ensure admissibility in legal contexts. Samples that test presumptively positive in Screening necessitate further confirmation.
If Screening indicates a presumptive positive, additional hair is extracted for the Extraction phase. Here, drugs are isolated from hair at a much lower concentration than other methods (e.g., urine, oral fluid), underscoring the complexity of hair drug screening.
Confirmation of a positive screen is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation as needed. Every step, from Accessioning to Confirmation, undergoes evaluation under the CAP (College of American Pathologists) Hair designation and accreditation according to ISO / IEC 17025 standards.
