Hair testing is now recognized as an effective method for identifying the use of drugs and alcohol. It offers a comprehensive history of alcohol and drug consumption by capturing markers within the hair strand's fibers as it grows. When hair near the scalp is collected, it can reveal drug and alcohol levels over a roughly 3-month period. Hair is easy to procure, challenging to tamper with, and uncomplicated to transport.
A sample measuring 1.5 inches with approximately 200 hair strands (similar to the width of a #2 pencil) taken closest to the scalp provides 100mg, which is the standard amount for both screening and confirmation. For tests such as EtG, additional elements, or beyond 10 panels, a sample weighing 150mg is advised. Using a jeweler’s scale to measure the sample is suggested. If head hair cannot be provided, a comparable amount of body hair may be used. "Head hair" refers only to scalp hair, while "body hair" includes all other types (like facial and axillary hair).
Process Overview
The laboratory processing of drug test results comprises four main stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample gets processed into the laboratory system. This phase ensures the sample is properly sealed and sent, assigns a LAN (Laboratory Accessioning Number), and completes any additional data entry not handled by an electronic chain of custody.
In Screening, there is a preliminary assessment for potential drug abuse. Although this step is cost-efficient and can exclude drug use in most samples, it must be followed by Confirmation for court admissibility. Positive findings from Screening necessitate additional confirmation.
When a sample tests positive during Screening, a portion of the original specimen is taken for Extraction. Here, drug presence is isolated from hair at lesser concentrations compared to other methods (e.g., urine or saliva), rendering hair drug screening notably challenging.
Positive screening outcomes undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS techniques. All suspected positive samples are cleansed before confirmation as required. This complete lab process from Accessioning to Confirmation adheres to standards set by CAP (College of American Pathologists) Hair and accredited by ISO / IEC 17025.
