Hair analysis is recognized as an effective method for identifying the use of drugs and alcohol. Hair captures a prolonged record of substance use by embedding biomarkers within the fibers of the developing hair shaft. When taken near the scalp, hair can offer around a 3-month detection timeframe for substances. Hair collection is straightforward, relatively secure against tampering, and convenient to transport.
A 1.5-inch portion containing roughly 200 hairs (similar in size to a #2 pencil) closest to the scalp provides 100mg of hair, which is the optimal sample for both analysis and confirmation. To analyze EtG, additional substances, and/or tests beyond 10 panels, a 150mg specimen is advised. It is suggested to measure the specimen using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be obtained. The term head hair refers exclusively to scalp hair, whereas body hair encompasses all other types (e.g., facial, axillary).
Process Overview
The laboratory processing of a drug test result consists of four fundamental stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the primary integration of a sample within a laboratory’s framework. This encompasses confirming the proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data input not supplied by an electronic chain of custody system.
Screening involves an initial rapid examination for drug abuse. While Screening is a cost-efficient method to exclude drug consumption for most samples, a positive result must be verified for legal acceptability. Any samples that are presumptively positive in Screening necessitate a secondary confirmation.
If a sample yields a presumptive positive in the Screening phase, additional hair is extracted from the original specimen and processed for Extraction. At this stage, drugs are isolated from hair at considerably lower concentrations than with alternative methods (such as urine or oral fluid), which is why hair drug testing is the most intricate method to execute.
Confirmation of any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. The full laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Despite being commonly termed "hair follicle tests", the assay examines the hair shaft, not the hair follicle beneath the scalp.
