Hair testing is now recognized as an effective method for detecting drug and alcohol use. Hair can encapsulate a long-term record of these substances by capturing biomarkers within the strands as they grow. When hair is obtained near the scalp, it offers a detection timeframe of up to about three months for alcohol and drugs. Collecting hair is straightforward, relatively resistant to tampering, and convenient to transport.
A hair sample measuring 1.5 inches, consisting of approximately 200 strands (similar to the thickness of a #2 pencil), yields 100mg of hair, which is the optimal sample size for both screening and confirmation purposes. For testing involving EtG, additional assessments, and/or tests exceeding 10 panels, a specimen weighing 150mg is advisable. It's suggested to weigh the sample using a jeweler’s scale. If scalp hair isn't available, the same quantity of body hair may be gathered. When we mention head hair, we specifically refer to scalp hair only. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The primary stages in lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the first step of integrating a sample into the laboratory's system. This process checks the sample's seal and shipping accuracy, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not covered by an electronic chain of custody.
Screening involves a preliminary swift drug presence check. Though Screening is cost-efficient for dismissing drug use in most samples, any positive results must be confirmed for court approval. Presumptive positives in Screening require further confirmation.
When a sample is likely positive in the Screening, more hair from the initial sample is used for Extraction. During this phase, drugs are drawn from hair at a much reduced concentration level compared to other tests (e.g., urine or oral fluid), contributing to hair drug testing’s complexity.
GC/MS, GC/MS/MS or LC/MS/MS techniques are employed to confirm any positive Screening outcomes. Presumptive positive samples are cleansed beforehand if required. The complete lab process from Accessioning to Confirmation undergoes inspection under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 standards accreditation.
