Hair testing is recognized as a robust means for identifying drug and alcohol consumption. It offers an extensive timeline by encasing biomarkers within the fibers of the hair strand as it grows. When clipped near the scalp, it can present a near 3-month detection window for both alcohol and other substances. Its collection is straightforward, it's relatively resistant to tampering, and it transports easily.
A sample measuring 1.5 inches from about 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp yields 100mg, the optimal amount for testing and verification. For tests like EtG, add-ons, or those exceeding 10 panels, 150mg of the hair specimen is advised. We suggest determining the specimen's weight using a jeweler's scale. If no scalp hair is accessible, a comparable quantity of body hair can be gathered. By head hair, we specifically mean scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).
Process Overview
The critical stages in a lab's processing of drug test outcomes include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the primary integration of a sample into a lab's framework. This process includes verifying the sample's seal and shipment, assigning a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data input absent in an electronic chain of custody framework.
Screening is the preliminary scanning for substance abuse. While screening efficiently eliminates drug use in most samples, any screen showing positivity requires confirmation for legal validity. Presumptive positive samples from this stage demand further confirmation.
For samples that show potential positivity during Screening, additional hair is taken from the first specimen and made ready for Extraction. During this phase, drugs are drawn from the hair at significantly lower concentrations than seen in other methods (such as urine or saliva), making hair drug testing a notably challenging methodology.
Confirming any initial positive findings is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed before confirmation when necessary. The full laboratory procedure, from Accessioning to Confirmation, undergoes review in accordance with the CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.

Note: The term "hair follicle tests" commonly used, refers to analysis of the hair strand itself, not the hair follicle beneath the scalp.
