Hair analysis is now recognized as an effective means for detecting drug and alcohol consumption. Hair captures a prolonged timeline of substance use by encasing markers within the strands as they grow. When taken near the scalp, hair can reveal a detection window extending up to about three months for drugs and alcohol. Hair is easy to gather, relatively hard to tamper with, and simple to transport.
A 1.5-inch segment of around 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp provides 100mg of hair, which is optimal for analysis. For EtG, add-ons, and/or screening more than 10 substances, 150mg of the sample is advised. Using a jeweler's scale to weigh the sample is suggested. If there isn't enough scalp hair, a corresponding portion of body hair may be used. References to head hair specifically pertain to scalp hair. Body hair encompasses all other types (like facial or axillary hair).
Process Overview
The process for determining a drug test result in the lab includes four critical phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about initially processing a specimen into the laboratory system. This phase checks that the sample was correctly sealed and sent, assigns a unique LAN (Laboratory Accessioning Number), and adds any necessary information not supplied by an automated chain of custody system.
Screening conducts a preliminary swift assessment for drugs of abuse. Screening is cost-efficient for negating the majority of drug use cases, but any positive results must be confirmed for legal validity. Any samples that test presumptively positive in Screening mandate a follow-up confirmation.
If the Screening stage indicates a presumptive positive, further hair is extracted from the original sample and readied for Extraction. Here, drugs are derived from hair at concentrations significantly lower compared to other methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methods.
Confirmation of any positive Screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned before confirmation as necessary. The complete process from Accessioning to Confirmation is audited under CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Though frequently labeled as "hair follicle tests," the evaluation examines the hair strand itself, not the follicle beneath the scalp.
