Utilizing hair testing has become recognized as an effective means for identifying alcohol and drug consumption. Hair offers a prolonged timeline of exposure by capturing biomarkers within its growing fibers. When sourced near the scalp, hair can present a detection timeframe of approximately three months for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.
A sample measuring 1.5 inches of roughly 200 hair strands (comparable to a #2 pencil in size) nearest the scalp provides 100mg of hair, the optimal amount for screening and confirmation. For EtG, supplementary tests, or panels over 10, a 150mg specimen is advised. We suggest utilizing a jeweler’s scale for weighing the specimen. If scalp hair is not accessible, an equivalent quantity of body hair may be gathered. When mentioning head hair, we specify scalp hair exclusively. Body hair encompasses all other types (facial, axillary, etc.).
Procedure Synopsis
The drug testing laboratory workflow encompasses four key phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample enters the lab's system, including ensuring its appropriate sealing and shipping, issuing a random LAN (Laboratory Accessioning Number), and performing any additional data entry absent from an electronic chain of custody framework.
Screening is a preliminary rapid assessment for substance abuse. Although cost-efficient for excluding drug usage in most samples, a positive screening requires confirmation for legal admissibility. Any samples presumptive of positivity in Screening necessitate successive confirmation.
For presumptive positives in the Screening stage, more hair is extracted from the original sample and prepared for Extraction. Here, drugs are isolated from hair at a substantially lower concentration compared to other methods (ex. urine or oral fluid), which contributes to the complexity of hair drug screening.
Positive screening result confirmation occurs through GC/MS, GC/MS/MS, or LC/MS/MS. All samples preliminarily positive undergo washing before confirmation as warranted. The full lab process from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
