Hair analysis is increasingly regarded as an effective means for identifying drug and alcohol use. Hair provides an extended timeline for alcohol and drug history by capturing biomarkers within the strands of emerging hair. When obtained near the scalp, hair can offer up to a 3-month detection timeframe for alcohol and drugs. Hair collection is easy, relatively hard to tamper with, and straightforward to transport.
A 1.5-inch length of around 200 hair strands (approximately #2 pencil thickness) nearest the scalp yields 100mg of hair, the optimal amount for screening and confirmation. For EtG testing, add-ons, or panels beyond 10, a specimen of 150mg is advised. We suggest weighing the sample using a jeweler’s scale. If no scalp hair is accessible, an equivalent amount of body hair may be gathered. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The primary stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is concerned with the initial incorporation of a sample into the lab’s system. This process ensures the sample was properly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data input not covered by an electronic chain of custody system.
Screening constitutes an initial swift assessment for drug presence. While it serves as a cost-effective means to exclude drug consumption in most samples, a positive screen must be confirmed for legal admissibility. All samples with presumptive positive results in screening necessitate secondary confirmation.
If a sample shows presumptive positive results during Screening, additional hair is extracted from the original sample and prepped for Extraction. This phase involves extracting drugs from hair at lower concentrations than other methods (e.g., urine or oral fluid), explaining why hair drug testing stands as the most challenging methodology.
Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive findings undergo washing before confirmation as needed. The comprehensive lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Note: Although commonly referred to as "hair follicle tests", the analysis targets the hair strand rather than the scalp's follicle.
