Hair analysis has become recognized as an effective means for detecting drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug use by embedding biomarkers within the strands of the growing hair. When gathered near the scalp, hair can offer a detection timeline of up to about three months for alcohol and other substances. Hair is easy to collect, relatively challenging to tamper with, and straightforward to transport.
A 1.5-inch segment consisting of approximately 200 hair strands (similar to the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample for both screening and verification. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the specimen is advised. We suggest measuring the specimen using a jeweler’s scale. If scalp hair is unavailable, an equivalent quantity of body hair can be obtained. When discussing head hair, we mean scalp hair specifically. Body hair encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The four primary steps in the lab processing for a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial processing of a sample into a laboratory’s framework. This involves confirming that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not provided by an electronic chain of custody system.
Screening consists of an initial rapid test for substances of abuse. Although Screening is an economical method to exclude drug usage in most samples, a positive screen must be verified to be permissible in court. Any samples deemed presumptively positive during Screening require subsequent confirmation.
If a sample is deemed presumptively positive in the Screening phase, more hair is extracted from the initial specimen and set for Extraction. During this phase, drugs are removed from hair at far lower concentrations than in other techniques (e.g., urine or oral fluid), which is why hair drug screening is among the most challenging methodologies to carry out.
Confirmation of any positive screening outcome is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptive positive undergo washing before confirmation as necessary. The entire laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair certification and the accreditation to ISO / IEC 17025 standards.
