Hair tests are recognized as an effective method for uncovering drug and alcohol use. Hair provides a comprehensive history of substance use by embedding biomarkers within the hair fibers. When sampled near the scalp, hair can offer a detection period of up to roughly 3 months for alcohol and other substances. The collection of hair is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch segment of approximately 200 hair strands (around the diameter of a #2 pencil) close to the scalp will yield 100mg of hair, which is the preferred quantity for both initial screening and subsequent confirmation. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advisable. We suggest measuring the hair sample with a jeweler's scale. Should scalp hair be unavailable, an equivalent quantity of body hair may be gathered. When we mention head hair, we are specifically referring to scalp hair. Body hair includes all other varieties (facial, axillary, etc.).
Process Overview
The laboratory procedure for drug test results includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of integrating a sample into a lab’s database. This process includes confirming the sample’s correct sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and filling in any data entry gaps not covered by an electronic chain of custody system.
Screening involves an initial rapid analysis for substances of abuse. Although Screening is an economical method to dismiss drug use in most samples, a confirmed positive result is necessary for courtroom validity. Any samples yielding a presumptive positive in Screening must undergo further confirmation.
If a sample tests presumptive positive during Screening, additional hair is extracted from the initial sample for Extraction. During Extraction, substances are pulled from hair at a significantly lower concentration than other methods (e.g., urine or oral swabs), making hair drug screening a challenging approach to execute.
Confirmation of any positive results from the Screening stage is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation as needed. The whole lab process from Accessioning to Confirmation undergoes review according to both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
