The utilization of hair testing is increasingly recognized as an effective mechanism for detecting drug and alcohol consumption. Hair captures a comprehensive timeline of substance use by embedding markers within the fibers of the hair as it grows. When sampled near the scalp, it can reveal drug or alcohol usage over an approximate period of up to three months. The collection process is straightforward, difficult to tamper with, and convenient for shipping.
Gathering a 1.5-inch segment of approximately 200 hair strands (akin to the thickness of a #2 pencil) nearest the scalp will provide 100mg of hair, which is the optimal quantity for both screening and confirmation. For tests involving EtG and/or panels exceeding 10, a specimen of 150mg is advised. It is suggested to measure the sample using a jeweler's scale. In the absence of scalp hair, a comparable quantity of body hair can be obtained. The term head hair specifically refers to scalp hair, whereas body hair encompasses all other types such as facial or axillary hair.
Process Overview
The laboratory procedure for processing a drug test result consists of four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary processing of the sample within a laboratory's system. This involves ensuring the sample was properly sealed and dispatched, assigning it a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry absent in an electronic chain of custody system.
Screening serves as an initial rapid assessment for substance abuse. Although it is a cost-efficient approach for excluding drug usage in most samples, a positive screen must be verified to stand in legal proceedings. Samples presumed positive during Screening necessitate secondary confirmation.
Should a sample test presumptively positive at the Screening stage, additional hair is retrieved from the original specimen for Extraction preparation. During this phase, substances are extracted from hair at a substantially lower concentration compared to other methodologies (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.
Confirmation of any positively screened sample is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation when required. The entire lab process, from Accessioning to Confirmation, undergoes stringent review according to both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standard accreditation.
