The utilization of hair testing has emerged as an effective method for uncovering the consumption of drugs and alcohol. Hair serves as an archive for substances by embedding biomarkers within the strands as they grow. When acquired near the scalp, hair can reveal substance use history for up to three months. It is straightforward to collect hair, not easily tampered with, and simple to transport.
A strand gathering of 1.5 inches, consisting of roughly 200 hairs (similar in size to a #2 pencil) and close to the scalp, will yield about 100mg, which is optimal for screening and validation. For tests involving EtG, additional elements, or more than ten panels, 150mg is advisable. The specimen should ideally be weighed using a jeweler’s scale. In the absence of scalp hair, a comparable volume of body hair can be used. 'Head hair' here exclusively refers to scalp hair, while 'body hair' pertains to all other types (such as facial or axillary hair).
Process Overview
The lab processing of drug test results encompasses four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary phase where a sample is integrated into a lab’s system. This step includes ensuring the sample was intact during shipment, allocating a random Laboratory Accessioning Number (LAN), and completing any necessary data entry that is absent from an electronic chain of custody system.
Screening is a preliminary and rapid identification of potential drug use. Although Screening is an economical method to negate drug usage in most samples, a positive outcome requires further confirmation for legal admissibility. Samples presumed positive during Screening indeed need a follow-up verification.
Should a sample test positive in Screening, more hair is extracted from the initial batch to prepare for the Extraction stage. In this phase, drugs are retrieved from hair at a lower concentration compared to other methods such as urine or oral fluid, making hair drug screening notably challenging.
Confirmation of any positive screening result is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed prior to Confirmation if necessary. The complete procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.
