Hair testing has emerged as a robust method for identifying drug and alcohol consumption. Hair serves as a long-term record of alcohol and drug presence by encasing biomarkers within the fibers of a developing strand. When collected near the scalp, hair can deliver up to a 3-month window for detecting alcohol and drugs. It is straightforward to gather, challenging to tamper, and easy to transport.
A 1.5-inch section of around 200 hair strands (roughly the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, which is the ideal amount for screening and affirmation. For EtG tests, add-ons, and/or evaluations above 10 panels, a sample size of 150mg is advisable. Using a jeweler’s scale for weighing the sample is recommended. Should scalp hair be unavailable, an equivalent quantity of body hair is acceptable. References to head hair imply only scalp hair, while body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial processing of a specimen into a lab’s system. This step ensures the sample is sealed and shipped correctly, allocates a random LAN (Laboratory Accessioning Number), and addresses any additional data entry absent from an electronic custody system.
Screening constitutes a preliminary examination for drugs. While Screening efficiently rules out drug usage on most samples, a positive finding necessitates confirmation to be valid in legal proceedings. Any samples showing positive signs upon Screening require subsequent confirmation.
For samples indicating positive signs during Screening, further hair is taken from the original sample and readied for Extraction. Here, drugs are extracted at a lower concentration than with other methods (e.g., urine or oral fluid), rendering hair drug testing the most challenging approach to execute.
Verification of any positive screening results is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All apparent positive samples are cleansed before confirmation as necessary. The complete lab process, from Accessioning to Confirmation, is examined under the CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 standards.
