Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. Hair captures long-term evidence of substances by embedding biomarkers within the fibers of the growing hair. If taken close to the scalp, hair can deliver a detection span of roughly 3 months for substances like drugs and alcohol. Collecting hair is straightforward, moderately hard to tamper with, and convenient to transport.
A sample measuring 1.5 inches with approximately 200 hair strands (similar to the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, the optimal quantity for analysis. For EtG, additional tests, and/or panels exceeding 10, a specimen weight of 150mg is suggested. Utilizing a jeweler’s scale to weigh the sample is advisable. Should scalp hair be lacking, equivalent body hair may be gathered. When mentioning head hair, it pertains exclusively to scalp hair. Body hair covers all other hair categories (facial, axillary, etc.).
Overview of Process
The laboratory processing of a drug test result follows four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial intake of a sample into a laboratory’s system. It involves checking that the sample was correctly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data entry not included by an electronic chain of custody system.
Screening is an introductory rapid inspection for illicit substances. While Screening offers a budget-friendly option to discount drug usage in most samples, a positive result in Screening needs to be confirmed for legal acceptability. Samples that show presumptive positive results in Screening necessitate subsequent validation.
For samples showing presumptive positivity during Screening, additional hair is extracted from the initial sample and prepped for Extraction. Drugs are extracted in this stage from hair at considerably lower concentrations than with alternate methods (e.g., urine or oral fluid), making hair drug testing the most challenging method to execute.
Confirmation of any positive result from screening is executed via GC/MS, GC/MS/MS or LC/MS/MS. All samples showing presumptive positivity undergo washing prior to confirmation if needed. The comprehensive laboratory procedure from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair standard and the accreditation of ISO/IEC 17025 criteria.
