Hair testing is increasingly viewed as an effective means for identifying drug and alcohol consumption. Hair offers an extended history of substance use by encasing biomarkers within the fibers of the hair strand as it grows. When extracted near the scalp, hair can reveal drug and alcohol use over a span of about three months. Hair is straightforward to collect, relatively hard to tamper with, and convenient to transport.
A 1.5-inch sample consisting of roughly 200 strands of hair (similar in size to a #2 pencil) closest to the scalp will yield 100mg of hair, optimal for screening and confirmation. For EtG, additional tests, or screenings exceeding 10 panels, 150mg of the sample is advisable. We suggest measuring the sample using a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair can be used. When mentioning head hair, it specifically refers to scalp hair. Body hair denotes all other hair types (e.g., facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results encompasses four vital steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial intake of a sample into a lab's system. This step includes verifying the sample was correctly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data entry absent from an electronic chain of custody system.
Screening involves an initial swift assessment for drugs of abuse. While Screening is a cost-efficient way to exclude drug presence in most samples, a positive result requires confirmation to be legally valid. Samples that appear positive during Screening necessitate further confirmation.
If a sample exhibits a presumptive positive in the Screening stage, additional hair is extracted from the original sample for Extraction preparation. In this phase, drugs are retrieved from hair at a much lower concentration than in other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.
Confirmation of any positive screening outcomes is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if necessary. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
