The utilization of hair testing for detecting substance use is considered highly effective. Hair acts as a repository for long-term exposure to alcohol and drugs by embedding biomarkers within the hair strand as it grows. Collected near the scalp, hair can offer an approximate detection timeframe of up to three months for substances. Hair collection is straightforward, challenging to tamper with, and easy to transport.
A specimen measuring 1.5 inches comprising roughly 200 hair strands (comparable to a #2 pencil) near the scalp yields 100mg, which is optimal for testing. For EtG, additional tests, or panels exceeding 10, 150mg is advisable. It's best to use a jeweler’s scale for measuring. If scalp hair isn't available, an equivalent quantity of body hair is acceptable. When mentioning head hair, it specifically refers to scalp hair. Body hair encompasses all other types such as facial and axillary.
Process Overview
The process for analyzing a drug test sample in the lab includes these four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step of integrating a sample into a lab’s system. It checks for proper sealing and shipping, assigns a unique LAN (Laboratory Accessioning Number), and completes any manual data entry not covered by an electronic chain of custody.
Screening serves as an initial assessment for substances of abuse. Although Screening effectively detects the absence of substances in most samples affordably, it necessitates confirmation for a positive result before being considered court-admissible. Presumptively positive samples in Screening demand secondary confirmation.
Should a sample test presumptively positive during Screening, additional hair from the original specimen is prepared for Extraction. Drugs are extracted at significantly lower concentrations than other techniques (e.g., urine or oral fluid), making hair drug testing particularly challenging.
Confirmation of any positive results from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Presumptive positive samples undergo washing before confirmation when required. The comprehensive laboratory procedure from Accessioning to Confirmation is monitored under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation.
