Hair testing has emerged as an influential method for identifying drug and alcohol consumption. Biomarkers are captured in the fibers of actively growing hair, providing a prolonged record of substance use. When cut near the scalp, it can offer a detection period of roughly three months for alcohol and drugs. The collection process is straightforward, moderately challenging to tamper with, and simple to mail.
An optimal sample involves a 1.5-inch segment of approximately 200 hair strands (roughly pencil-thick) nearest to the scalp, supplying 100mg of hair for screening and confirmation. For EtG, additions, or tests exceeding 10 panels, 150mg is advisable. It's best to weigh this sample using a jeweler’s scale. In the absence of scalp hair, an equivalent portion of body hair can be taken. By head hair, we mean only scalp hair. Body hair encompasses all other types (face, armpits, etc.).
Process Overview
The key phases in lab processing for a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is incorporated into the lab’s system, ensuring it was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any extra data not covered by an electronic chain of custody.
Screening offers a quick initial assessment for drugs of abuse. Although a cost-efficient way to clear most samples, a positive result needs legal admissibility, requiring further confirmation. Samples that test positive at this stage need additional verification.
If a sample tests positive initially, more hair is taken from the first sample for Extraction. Here, drugs are isolated from hair at lower concentrations than other methods (such as urine or saliva), which makes hair drug assays the toughest method to conduct.
Any positive screening is validated through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo washing before confirmation. The whole laboratory process from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
