Hair testing is increasingly recognized as an effective means to detect drugs and alcohol. The hair strands capture biomarkers within their fibers, providing a lasting record of drug or alcohol use. When a sample is taken near the scalp, it can yield a detection window for alcohol and drugs stretching up to approximately 3 months. Hair collection is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch sample, comprising roughly 200 strands making up the diameter of a #2 pencil, located close to the scalp generates 100mg of hair, which is optimal for screening and confirmation. For EtG, additional tests, and tests exceeding 10 panels, 150mg of hair is suggested. We advise utilizing a jeweler’s scale to weigh the sample. If scalp hair is not available, a corresponding amount of body hair may be used. “Head hair” specifically refers to scalp hair. “Body hair” covers other hair types (e.g., facial, axillary, etc.).
Process Overview
The key phases in the laboratory processing of a drug test result consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning embodies the preliminary processing phase of integrating a sample into the laboratory’s system, confirming the sample's proper sealing and shipping, assigning a Laboratory Accessioning Number (LAN) at random, and completing any data entry not included by an electronic chain of custody system.
Screening is the initial rapid evaluation for drugs of abuse. Although Screening is an economical method for dismissing drug use in most samples, a positive result demands confirmation for court admissibility. Samples that are presumptively positive in Screening will require additional confirmation.
In cases of a presumptive positive during the Screening phase, additional hair is obtained from the initial specimen for Extraction. In this stage, drug extraction occurs at a much lower concentration than other methodologies (e.g., urine or oral fluid), making hair drug testing the most intricate methodology to implement.
The Confirmation of any positive screen is executed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positives are washed appropriately before confirmation. The entire laboratory procedure from Accessioning through to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
