Regarded as an effective method, hair testing serves in detecting drug and alcohol consumption. Hair fibers trap biomarkers within the strand, offering a prolonged timeline of alcohol and drug use. When taken near the scalp, a hair test can present a detection range of nearly 3 months for substances. Collection is straightforward, resistant to tampering, and conveniently shippable.
A 1.5-inch hair sample comprising roughly 200 strands (approximating a #2 pencil) from the scalp provides 100mg, the optimal amount for both screening and confirmation procedures. For EtG, additional tests, or panels exceeding 10, a specimen of 150mg is advisable. Utilizing a jeweler’s scale for weighing the sample is suggested. Should scalp hair be inaccessible, a similar quantity of body hair can be used. References to head hair apply solely to scalp hair, whereas body hair encompasses all other variants like facial and axillary types.
Process Overview
Accessioning, Screening, Extraction, and Confirmation are the four key steps in processing drug test results in the lab.
Accessioning includes the sample's initial entry into the lab's system, confirming it was correctly sealed and shipped, assigning a LAN (Laboratory Accessioning Number), and filling in any supplementary data absent from an electronic chain of custody.
Screening entails a preliminary rapid check for drug presence. While cost-effective for excluding drug use across most samples, a positive outcome requires confirmation for court usability. Any samples testing positive in Screening need secondary verification.
For samples testing positive in Screening, additional hair is extracted from the primary sample and readied for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology.
Confirmed positive results are validated using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, suspected positive samples are washed if necessary. Every step from Accessioning to Confirmation is scrutinized under CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
