Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair contains an extensive timeline of drug and alcohol intake by embedding biomarkers within the fibers of the hair as it grows. When trimmed near the scalp, hair samples offer a detection timeframe of up to three months for both alcohol and drugs. This method is straightforward to gather, challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches with approximately 200 hair strands (about the thickness of a #2 pencil) near the scalp yields 100mg, which is the optimal amount for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a 150mg specimen is advised. It's recommended to use a jeweler’s scale for weighing the sample. Should scalp hair not be available, a similar quantity of body hair can be used. "Head hair" pertains solely to scalp hair, whereas "body hair" covers other hair types (facial, axillary, etc.).
Process Overview
The process for laboratory assessment of a drug test result comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial phase of integrating a sample into a lab’s system. This process includes ensuring the sample is sealed and sent correctly, assigning a unique LAN (Laboratory Accessioning Number), and carrying out any additional data input absent from an electronic chain of custody system.
Screening performs a preliminary rapid check for drug abuse. Although Screening is an economical method to eliminate drug use in most samples, any positive screen must undergo confirmation to be court-admissible. Samples that test presumptively positive with Screening necessitate additional confirmation.
In cases where a sample tests presumptively positive during the Screening phase, more hair is taken from the initial sample and processed for Extraction. During Extraction, drugs are isolated from the hair at a notably lower concentration than other techniques (e.g., urine or oral fluid), signifying why hair drug screening is fundamentally challenging to execute.
Verification of any positive Screening outcome is completed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are cleaned as needed. The entire lab process from Accessioning to Confirmation is examined under both CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests", the procedure examines the hair strand rather than the follicle beneath the scalp.
