Hair analysis is now considered an effective method to identify substance and alcohol consumption. Hair captures a prolonged record of alcohol and other substances by embedding chemical markers within the fibers of the hair shaft as it grows. When trimmed near the scalp, hair offers a detection period of up to roughly three months for alcohol and other substances. Collecting hair is straightforward, somewhat resistant to tampering, and simple to dispatch.
A 1.5-inch segment comprising about 200 hair strands (approximately the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is optimal for initial tests and verifications. To perform tests like EtG, additional analyses, or screenings beyond 10 panels, 150mg of the sample is advisable. It’s best to weigh this sample using a jeweler’s scale. If scalp hair cannot be obtained, a comparable amount of body hair can be used instead. Mention of head hair specifically pertains to scalp hair, while body hair encompasses all other hair types (e.g., facial, armpit, etc.).
Process Overview
The primary phases in laboratory handling of a drug test outcome consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary treatment of a sample within a lab’s protocol. This involves confirming the sample was correctly sealed and dispatched, creating a random LAN (Laboratory Accessioning Number), and fulfilling any further data entry absent in an electronic chain of custody framework.
Screening serves as an initial swift assessment for drug misuse. While it’s a cost-efficient method to exclude drug intake in most samples, any positive results from Screening need validation to be admissible legally. Samples flagged as presumptively positive during Screening require further confirmation.
In cases where a sample shows presumptive positivity during Screening, extra hair is extracted from the initial sample and readied for Extraction. During Extraction, drugs are drawn from hair at much lower concentrations compared to alternative techniques (e.g., urine or oral fluids), thereby making hair drug screening the most challenging methodology to execute.
Positive results from Screening undergo Confirmation through techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed prior to confirmation as necessary. Every stage from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair category and accreditation to ISO / IEC 17025 criteria.

Note: Despite often being termed as "hair follicle tests", the test examines the hair strand itself rather than the follicle below the scalp.
