Hair testing is now acknowledged as an effective method for identifying drug and alcohol consumption. Hair offers a retrospective account of substance usage by encapsulating biomarkers in the fibers of the growing hair shaft. When obtained near the scalp, hair can offer a detection period of roughly up to 3 months for both alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and convenient for shipping.
A 1.5-inch segment consisting of approximately 200 hair strands (akin to the size of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the optimal amount for testing and verification. For EtG, add-ons, and/or screenings beyond 10 panels, 150mg of the specimen is advised. We suggest weighing the specimen with a jeweler’s scale. If scalp hair is not available, the same amount of body hair may be gathered. "Head hair" specifically refers to scalp hair. "Body hair" encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result includes four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is integrated into a laboratory’s database. This phase ensures that the sample is sealed and transported correctly, assigns a unique LAN (Laboratory Accessioning Number), and fills in any missing data not recorded by an electronic chain of custody system.
Screening provides an initial rapid assessment for drugs. While screening is a budget-friendly method for excluding drug use in the majority of samples, confirmed positivity is necessary for legal admissibility. Samples that test presumptive positive in screening must undergo confirmation.
If screening indicates presumptive positivity, additional hair from the original sample is extracted and prepared for Extraction. Here, drugs are withdrawn from hair at lower concentrations compared to other methods (like urine or saliva), making hair drug testing among the most intricate to execute.
Confirmation of any screening positives is done using GC/MS, GC/MS/MS or LC/MS/MS. Samples that are presumptive positive are cleansed before confirmation as necessary. The entire laboratory process from Accessioning to Confirmation adheres to the CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.
