Testing hair has emerged as an effective means of identifying drug and alcohol consumption. Hair offers an extended record of alcohol and drug use by embedding biomarkers within the hair's growing fibers. When taken near the scalp, hair can reveal usage within a detection window of up to roughly 3 months for alcohol and drugs. Hair is easy to gather, relatively challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches, containing around 200 strands of hair (similar to a #2 pencil's size) near the scalp, will produce 100mg of hair, which is the optimal quantity for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, it is advisable to collect 150mg of the hair. It is beneficial to assess the sample's weight using a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair is acceptable. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
In processing a drug test result in a lab, the key steps include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a specimen into a lab’s workflow. This step ensures the sample was properly sealed and transported, assigns a LAN (Laboratory Accessioning Number), and completes any data recording absent from an electronic chain of custody system.
Screening involves a preliminary expedited assessment for drugs of abuse. Although Screening offers a cost-efficient approach to dismiss drug usage in most cases, a screen with positive indications must be validated for legal admissibility. Any samples presumed positive in Screening necessitate further confirmation.
In cases where a sample shows positive indications in Screening, additional hair is extracted from the original sample for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations compared to other techniques (such as urine or oral fluid). This complexity makes hair drug screening one of the most challenging methodologies to execute.
Verification of any positive screening result is achieved through techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Any samples with presumptive positives are cleansed before confirmation if required. The comprehensive lab process, from Accessioning to Confirmation, is conducted in line with both the CAP (College of American Pathologists) Hair specifications and the accreditation as per ISO / IEC 17025 standards.
