Hair testing is now recognized as an effective method for identifying the use of drugs and alcohol. Hair offers an extended record of substance use by embedding biomarkers within the strands as they grow. When collected near the scalp, this can reveal drug and alcohol usage over a period of up to three months. Collecting hair is easy, hard to tamper with, and convenient to transport.
A sample measuring 1.5 inches consisting of roughly 200 hairs (similar in size to a #2 pencil) near the scalp yields 100mg, which is ideal for screening and verification. For EtG, additional tests, or panels exceeding ten, 150mg is suggested. It's advisable to weigh samples on a jeweler’s scale. If scalp hair cannot be obtained, the same quantity of body hair can be used. Head hair pertains exclusively to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample undergoes initial processing into the lab’s system, ensuring it was sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data input absent from an electronic chain of custody system.
Screening provides an initial assessment for substances of abuse. It serves as a cost-effective measure to exclude drugs in most samples; however, a positive screen necessitates confirmation for legal admissibility. Samples that are presumptively positive require a secondary confirmation process.
Should a sample be presumptively positive in Screening, additional hair is extracted from the initial sample and prepped for Extraction. In this procedure, drugs are isolated from hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging to conduct.
Confirmation of positive screenings is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicated as presumptively positive are cleaned before confirmation when necessary. The entirety of the lab procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.
