Hair testing is recognized as an effective method for identifying drug and alcohol consumption. By capturing biomarkers within the fibers, hair strands offer an extensive history of substance use. When taken near the scalp, the hair can reveal drug and alcohol use over roughly three months. Hair collection is straightforward, hard to tamper with, and easy to transport.
A 1.5-inch sample consisting of around 200 hair strands (approximately as thick as a #2 pencil) collected from near the scalp yields 100mg, which is ideal for evaluating and confirming. For EtG, additional tests, or panels beyond 10, 150mg of hair is advised. Accurate weighing on a jeweler's scale is recommended. If scalp hair cannot be obtained, a comparable amount of body hair is acceptable. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing drug test results involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step of entering a sample into a lab's system, which includes ensuring the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any missed data entry absent from an electronic chain of custody system.
Screening involves a preliminary assessment for drug use. While Screening is an economical way to negate drug usage in most samples, a positive result needs confirmation to be court-admissible. All samples that test positive during Screening require a secondary confirmation.
For samples testing positive during Screening, further hair is obtained from the original sample and prepared for Extraction. At this point, drugs are extracted from hair at lesser concentrations than through other methods (e.g., urine or oral fluids), making hair drug screening the most challenging to execute.
Confirmation of any initial positive result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumpive positive samples are washed prior to confirmation when necessary. The entire process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
