Hair testing is recognized as an effective means for identifying drug and alcohol consumption. Hair strands capture biomarkers of alcohol and drugs in their growing fibers, providing a historical record. When collected near the scalp, hair samples can offer a detection period of up to three months for alcohol and drugs. The collection process is straightforward, the potential for tampering is minimal, and shipping is uncomplicated.
A 1.5-inch section consisting of about 200 hair strands (equivalent to the diameter of a #2 pencil) near the scalp yields 100mg of hair, which is the optimal quantity for analysis and verification. For tests including EtG, additional components, and/or panels exceeding 10, a 150mg sample is ideal. Using a jeweler's scale is advised to measure the specimen. In cases where scalp hair is lacking, similar body hair quantities can be collected. Head hair pertains specifically to scalp hair, while body hair includes other types (e.g., facial, axillary).
Process Overview
Drug test result processing in the lab involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially logged into the lab's system. This step ensures the sample's seal and shipment integrity, assigns a random LAN (Laboratory Accessioning Number), and completes additional data entry if an electronic chain of custody system isn’t available.
Screening is the initial efficient assessment for drug presence. Although it is a cost-saving method to eliminate drug usage for most samples, positive screening results require confirmation for legal admissibility. Samples indicating a presumptive positive in Screening necessitate further verification.
For samples showing presumptive positivity in Screening, additional hair is extracted from the initial sample for further analysis. In this phase, drugs are removed from hair at lower concentrations than in other methods (like urine or oral fluid), explaining why hair drug screening is challenging.
Confirmation of positive results from Screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing before Confirmation as needed. The full laboratory process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and accredited by ISO / IEC 17025 standards.

Note: Frequently termed as "hair follicle tests," the analysis actually inspects the hair strand, not the follicle beneath the scalp.
