Hair testing is now recognized as an effective method for uncovering alcohol and drug consumption. Hair serves as an indicator of prolonged substance use by encasing biomarkers within the strands of hair as they grow. When hair is collected near the root, it can provide a detection period of up to 90 days for alcohol and other substances. Hair collection is straightforward, less prone to manipulation, and easy to transport.
A 1.5-inch cut of around 200 hair strands (comparable in thickness to a #2 pencil) from the scalp yields approximately 100mg of hair, which is the preferred amount for preliminary and confirmatory testing. For tests involving EtG, additional analyses, or over 10 panels, it is recommended to use 150mg of the sample. We advise weighing the sample using a jeweler's scale. If no scalp hair is available, a similar quantity of body hair may be used. References to head hair pertain solely to scalp hair, while body hair encompasses all other hair types (like facial or axillary hair).
Process Overview
The drug test laboratory procedure encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning integrates the sample into the laboratory's process. This includes checking if the sample was properly sealed and sent, generating a random LAN (Laboratory Accessioning Number), and inputting any additional information not provided by electronic chain of custody methods.
Screening provides an initial overview for substances of abuse. While Screening efficiently excludes drugs in most samples, any positive findings must be confirmed for legal acceptability. Presumptive positives in Screening require additional verification.
Should Screening indicate a presumptive positive, additional hair is extracted from the sample for the Extraction step. At this phase, drugs are separated from hair at lower concentrations compared to techniques like urine or saliva testing, marking hair testing as the technically most challenging method.
Confirming a positive screening result involves GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that test positive in Screening are cleansed before Confirmation if necessary. The entire process, spanning from Accessioning to Confirmation, undergoes review according to both CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.
