Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair retains a prolonged history of alcohol and drug intake by capturing biomarkers within the strands of hair as it grows. When sampled close to the scalp, hair can reveal drug and alcohol use over approximately a 3-month period. It's easy to collect, challenging to tamper with, and simple to transport.
A hair sample measuring 1.5 inches and consisting of around 200 strands (roughly the diameter of a number two pencil) near the scalp yields 100mg of hair—ideal for both screening and confirmation. For EtG, additional tests, or testing beyond 10 panels, 150mg of hair is advisable. Using a jeweler’s scale to measure the specimen is recommended. If scalp hair is not available, an equivalent mass of body hair can be used instead. "Head hair" refers specifically to scalp hair, while "body hair" includes all other types of hair (e.g., facial, axillary).
Process Overview
There are four primary steps in the laboratory analysis of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial sample entry into a laboratory system, ensuring the sample is properly sealed and shipped, generating a random LAN (Laboratory Accessioning Number), and filling out any other necessary information not captured by an electronic chain of custody system.
Screening conducts a preliminary analysis for drugs of abuse. Although Screening is an economical method for ruling out drug presence in most samples, confirmed positive results are essential for legal proceedings. Presumptive positives in Screening necessitate further confirmation.
For samples that test presumptively positive in the Screening phase, additional hair is extracted from the original sample and prepared for the Extraction step. Here, drug extraction occurs at significantly lower concentrations than urine or oral fluid methodologies, making hair testing uniquely challenging.
Confirmation of positive Screening outcomes is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that test presumptively positive undergo washing prior to confirmation if necessary. The entire process from Accessioning through Confirmation is conducted under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.
