Hair analysis has gained recognition as an effective means for identifying drug and alcohol usage. Hair captures a long-term record of alcohol and other drugs by locking biomarkers within the fibers of the growing hair strand. When taken near the scalp, hair can provide up to a roughly 3-month detection period for alcohol and other drugs. Hair is easy to collect, relatively challenging to adulterate, and straightforward to transport.
A 1.5-inch hair sample consisting of approximately 200 strands (about the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal sample for testing and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advisable. We suggest weighing the sample using a jeweler’s scale. If scalp hair is unavailable, an equivalent quantity of body hair may be gathered. When addressing head hair, we are specifically referring to scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The four critical steps in the laboratory procedure of determining a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the initial handling of a sample into a lab’s system. This step includes ensuring that the sample was sealed and delivered properly, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data input not covered by an electronic chain of custody system.
Screening entails a preliminary assessment for drugs of abuse. Although Screening is an economical method to rule out drug usage in most samples, a positive screen must be validated to be valid in legal proceedings. Any samples showing presumptive positivity in Screening need a follow-up confirmation.
Should a sample show presumptive positivity during the Screening phase, additional hair is extracted from the original sample and readied for Extraction. In this phase, substances are extracted from hair at a substantially lower concentration than other techniques (e.g., urine or oral fluid), hence making hair drug screening the most complex technique to perform.
Verification of any positive screening result is completed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing prior to confirmation as necessary. The entire lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.
