Hair analysis is now widely acknowledged as an effective method for identifying the use of drugs and alcohol. By encasing biomarkers within the fibers of the growing strand, hair records a comprehensive history of alcohol and drug use. When clipped close to the scalp, hair samples can reveal a substance use history of up to about three months. Collection is straightforward, it's not easy to tamper with, and is convenient for shipping.
A 1.5-inch segment consisting of approximately 200 hairs (roughly equivalent to the size of a #2 pencil) nearest to the scalp yields 100mg, the preferred quantity for both initial screening and confirmation. For EtG, supplemental assessments, and/or extensive testing beyond 10 panels, 150mg is optimal. Using a jeweler’s scale for measuring the sample is suggested. If scalp hair cannot be obtained, a corresponding volume of body hair can be used. References to head hair specifically pertain to scalp hair. Body hair includes all other types (e.g., facial, axillary).
Process Overview
The primary stages in the lab proceeding of a drug test result comprise Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into a lab system. This stage ensures the sample was correctly sealed and dispatched, allocates a unique LAN (Laboratory Accessioning Number), and fills out any required data not provided by an electronic chain of custody framework.
Screening involves an initial quick check for substances of abuse. Although Screening is cost-effective in eliminating drug usage for the bulk of samples, a positive outcome necessitates Confirmation to be valid in legal proceedings. Any samples that show a presumptive positive in Screening will need a secondary validation.
If a sample is deemed presumptively positive during Screening, further hair is extracted from the original specimen and readied for Extraction. This stage involves extracting drugs from hair at substantially lower concentrations than other methods (e.g., urine or oral fluid), which is why hair drug analysis remains the most challenging method to execute.
Positive Screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo a wash before confirmation if required. The entire lab operation from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Commonly known as "hair follicle tests", the analysis focuses on the hair strand itself rather than the follicle beneath the scalp.
