Hair testing has gained recognition as a robust method for identifying drug and alcohol consumption. Hair offers an extensive record of alcohol and other substances by capturing biomarkers within the fibers of the expanding hair strand. When collected near the scalp, hair can deliver about a 3-month detection range for alcohol and drugs. Hair is easy to collect, somewhat resistant to adulteration, and straightforward to ship.
A 1.5-inch section of roughly 200 strands of hair (approximately the diameter of a #2 pencil) closest to the scalp will provide 100mg of hair, the perfect amount for analysis and confirmation. For EtG, supplementary tests, and/or assessments beyond 10 panels, 150mg of the sample is advised. It is recommended to measure the sample on a jeweler’s scale. Should scalp hair be unavailable, a similar amount of body hair can be collected. When we mention head hair, we refer solely to scalp hair. Body hair includes all other hair categories (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a laboratory’s framework. This step involves verifying the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry missing from an electronic chain of custody system.
Screening consists of an initial rapid evaluation for drugs of abuse. While Screening is a financially efficient method to exclude drug usage for most samples, a positive screen requires confirmation to be valid in legal proceedings. Any samples deemed presumptively positive in Screening necessitate a secondary confirmation.
If a sample is presumptively positive during the Screening phase, additional hair is extracted from the initial sample and prepped for Extraction. In this phase, drugs are withdrawn from hair at a notably lower concentration than in other methods (e.g., urine or oral fluid), making hair drug screening the most complex methodology to execute.
Confirmation of a positive screening result is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo cleaning prior to confirmation if needed. The complete laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly termed "hair follicle tests", the analysis is actually conducted on the hair strand, not on the follicle beneath the scalp.
