The perception of hair testing as an effective method for detecting drug and alcohol consumption has grown. Hair allows for a prolonged overview of substance use by embedding biomarkers within its evolving fibers. When hair is harvested near the scalp, it can reveal up to a three-month timeline for drug and alcohol presence. The collection of hair is straightforward, relatively resistant to tampering, and easy to transport.
For optimal analysis and verification, a 1.5-inch segment comprised of roughly 200 hair strands (comparable to a #2 pencil) near the scalp can yield 100mg, which is deemed ideal. However, for EtG, additional substances, or tests exceeding ten panels, a sample of 150mg is advised. It's best to measure the sample using a precision jeweler’s scale. If scalp hair is not an option, a similar amount of body hair can be used. All references to head hair specifically pertain to scalp hair, whereas body hair encompasses all other types (e.g., facial, axillary).
Process Overview
The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially logged into the lab's system. This step ensures the sample is properly sealed and delivered, assigns an arbitrary LAN (Laboratory Accessioning Number), and inputs any additional data not covered by an electronic custody chain.
Screening performs an initial, rapid assessment for drug presence. As a cost-efficient method, it can often rule out substance use in most samples; however, to be legally valid, a positive Screen requires confirmation. Any samples indicated as positive during Screening need a follow-up confirmation test.
If Screening suggests a positive, more hair from the initial sample is set aside for Extraction. In this step, drug compounds are extracted from the hair at a dramatically reduced concentration compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug analyses.
For Confirmation, any suspect positive outcomes are validated via GC/MS, GC/MS/MS, or LC/MS/MS. Samples testing positive are cleansed before Confirmation as necessary. The entire flow from Accessioning to Confirmation is vetted under the CAP (College of American Pathologists) Hair designation and aligned with ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Despite often being named "hair follicle tests," the evaluation targets the hair strand and not the follicle beneath the scalp.
