Hair tests are now recognized as an effective means for detecting drug and alcohol consumption. Hair strands retain biomarkers in their fibers, offering a historical profile of alcohol and drug use. When gathered near the scalp, hair can reveal a drug and alcohol use record spanning up to three months. Collection is straightforward, tampering is difficult, and shipment is uncomplicated.
A 1.5-inch section containing around 200 hair strands (similar in size to a #2 pencil) taken close to the scalp yields 100mg of hair, an ideal quantity for both screening and confirmation. For tests like EtG, add-ons, or those exceeding 10 panels, a 150mg sample is advised. We suggest using a jeweler’s scale for accuracy in weighing the sample. If scalp hair is not available, a comparable amount of body hair is acceptable. When we mention head hair, we mean exclusively scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially integrated into the lab's system. This step ensures the sample was correctly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and completes any additional data entries absent from an electronic chain of custody system.
Screening offers a preliminary rapid assessment for substance abuse. While Screening is a cost-efficient method to eliminate drug use in most samples, a positive result requires confirmation before being considered valid in legal contexts. Samples that test presumptively positive in Screening necessitate a secondary confirmation.
If Screening results are presumptively positive, additional hair is extracted from the initial sample for the Extraction phase. At this stage, drugs are extracted from hair in significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which contributes to the complexity of performing hair drug tests.
Positive Screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are washed as necessary. The entire process, from Accessioning to Confirmation, adheres to both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.
