Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair retains a comprehensive record of alcohol and drugs by embedding biomarkers in the fibers of the developing hair strand. When sourced near the scalp, hair can reveal a window of detection extending up to roughly 3 months for alcohol and drugs. Hair is straightforward to collect, moderately challenging to tamper with, and uncomplicated to transport.
A 1.5-inch section of around 200 hair strands (around the width of a #2 pencil) nearest to the scalp will produce 100mg of hair, which is the optimal sample size for testing and verification. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg sample is advised. We suggest measuring the sample using a jeweler’s scale. If scalp hair is unavailable, an equivalent quantity of body hair can be gathered. "Head hair" refers exclusively to scalp hair. "Body hair" includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the entry of a sample into a laboratory system. This step verifies the correct sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entry from an electronic chain of custody system.
Screening involves an initial evaluation for drugs of abuse. While Screening offers a cost-efficient method to exclude drug usage in most samples, a positive result requires verification for court admissibility. Samples with presumptive positive results in Screening necessitate further confirmation.
Presumptive positive samples in Screening require more hair from the initial specimen for Extraction. In this phase, drugs are removed from hair at significantly lower concentrations than in methods like urine or oral fluid, highlighting the complexity of hair drug screening.
Confirmation of a positive screening result is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation if needed. The complete laboratory process from Accessioning to Confirmation is assessed according to both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests," the examination focuses on the hair strand rather than the hair follicle under the scalp.
