The utilization of hair testing has emerged as an effective means for identifying the consumption of drugs and alcohol. Hair provides an extended overview of alcohol and drug usage by capturing biomarkers within the growing hair fiber. When obtained near the scalp, hair can reveal drug and alcohol usage within a detection period of up to three months. The collection process for hair is straightforward, resistant to tampering, and convenient for shipping.
A sample measuring 1.5 inches, approximately 200 hair strands (comparable to the thickness of a number 2 pencil) next to the scalp, provides 100mg of hair, which is the optimal sample amount for both screening and confirmation tests. For tests such as EtG, add-ons, or those exceeding 10 panels, 150mg of the sample is suggested. It is advisable to use a jeweler's scale to weigh the sample. Should scalp hair be inaccessible, an equivalent quantity of body hair may be utilized. References to head hair pertain solely to scalp hair, while body hair includes all other forms (e.g., facial, axillary, etc.).
Process Overview
The process of obtaining a drug test result through laboratory procedures consists of four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary integration of a sample into the laboratory's system. This process ensures the sample's seal and proper shipment, assigns it a random Laboratory Accessioning Number (LAN), and completes any supplementary data entry absent in the electronic chain of custody system.
Screening is a swift preliminary assessment for substance abuse. Although Screening offers a cost-effective measure to negate drug use in most samples, a positive screening result necessitates confirmation to be permissible in legal proceedings. Samples returning a presumptive positive result during Screening demand further confirmation.
Suppose a sample registers presumptive positivity during the Screening phase. In this case, additional hair is extracted from the original sample and readied for Extraction. This stage involves extracting drugs from hair at considerably lower concentrations than methodologies such as urine or oral fluid, making hair drug testing among the most challenging methodologies to execute.
The confirmation of any positive screening involves GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples indicating presumptive positivity undergo washing before confirmation, as needed. The entire laboratory procedure, from Accessioning through to Confirmation, is scrutinized under the College of American Pathologists (CAP) Hair designation, alongside accreditation to ISO / IEC 17025 standards.
