The method of hair testing has become recognized as an effective means for uncovering drug and alcohol consumption. Hair acts as a repository for biochemical markers, capturing them within the fibers as hair strands grow. When taken near the scalp, hair samples offer a detection window of nearly 90 days for alcohol and drug use. Hair collection is straightforward, hard to tamper with, and convenient for transport.
A 1.5-inch section consisting of about 200 hair strands (roughly matching the width of a #2 pencil) nearest the scalp equates to 100mg of hair, which is optimal for screening and confirmation. For EtG and additional testing or tests beyond 10 panels, a 150mg sample is advisable. We suggest using a jeweler’s scale for weighing the sample. Should scalp hair be inaccessible, a corresponding quantity of body hair can be gathered. Note that head hair specifically refers to scalp hair, while body hair encompasses all other types of hair (including facial and axillary hair).
Process Overview
Four essential steps outline the lab protocols for a drug test, including Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the beginning stage, integrating a sample into a lab’s database. This stage verifies proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and addresses any additional data entry needs not fulfilled by an electronic chain of custody system.
Screening serves as an initial examination for substance abuse. As an economical way to exclude drug presence in most samples, a positive screening demands confirmation for legal credibility. Presumptively positive samples during Screening need further validation.
When a sample is deemed presumptively positive in the Screening phase, additional hair is extracted from the original sample and readied for Extraction. This phase involves retrieving drugs from hair at a significantly reduced concentration compared to other methods (e.g., urine or oral fluid), underscoring the complexity of performing hair drug screening.
Confirmation of any positive screening outcome utilizes techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing when necessary before confirmation. The comprehensive laboratory workflow from Accessioning through to Confirmation adheres to both CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standards of accreditation.
