The role of hair testing has evolved into a crucial mechanism for identifying the use of drugs and alcohol. Hair serves as a historical record for alcohol and other substances by encapsulating biomarkers within the fiber structure of the hair strand as it grows. Sourced near the scalp, hair offers a potential detection span for alcohol and other agents spanning up to roughly three months. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A hair segment of 1.5 inches, consisting of approximately 200 strands (similar to the circumference of a #2 pencil), collected nearest to the scalp will provide 100mg, which is the optimal sample size for both screening and verification purposes. For EtG, additional tests, and/or assessments expanding beyond 10 panels, a 150mg specimen is advocated. Utilizing a jeweler's scale for specimen measurement is advised. In the absence of scalp hair, a comparable quantity of body hair may be obtained. By "head hair," we explicitly mean scalp hair. Body hair encompasses all other categories of hair (facial, axillary, etc.).
Process Overview
There are four fundamental phases in the laboratory process for generating a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the primary phase of integrating a sample into a lab's framework. It entails the verification of the sample's seal and shipping condition, the assignment of a random LAN (Laboratory Accessioning Number), and the finalization of any additional data entry not facilitated by an electronic chain of custody protocol.
Screening is a preliminary, swift examination for drug misuse. Although Screening is a cost-efficient method for excluding drug use in most samples, a confirmed positive result is necessary for court admissibility. Any samples identified as presumptively positive during Screening mandate a subsequent confirmation test.
In instances where a sample is presumptively positive at the Screening phase, additional hair is extracted from the initial specimen and readied for Extraction. During this process, drugs are isolated from the hair at notably lower concentrations than in other techniques (e.g., urine or oral fluid), which underscores why hair drug screening is the most complex technique to conduct.
Verification of any positive screen involves methodologies such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation if required. The laboratory process from Accessioning to Confirmation is conducted in accordance with both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
