Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. Hair offers an extensive history of substance use by encapsulating biomarkers within the fibers of the hair as it grows. When obtained near the scalp, hair samples can reveal substance presence for a period of approximately three months. Collecting hair is straightforward, challenging to tamper with, and simple to transport.
A specimen of 1.5 inches consisting of roughly 200 hair strands (comparable to the girth of a #2 pencil) close to the scalp yields 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional tests, or analyses beyond 10 panels, a 150mg specimen is advisable. It is suggested to measure the specimen using a jeweler’s scale. If head hair is unavailable, an equivalent volume of body hair can be gathered. Referring to head hair implies scalp hair exclusively, while body hair comprises all other types (facial, axillary, etc.).
Process Overview
The procedure for processing a drug test result in a laboratory encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a specimen into a laboratory's system. This step involves confirming that the specimen was sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not included by an electronic chain of custody system.
Screening consists of a preliminary swift assessment for substance misuse. While Screening provides an economical method to exclude drug presence in most samples, any positive result requires confirmation for court admissibility. Samples exhibiting presumptive positive results in Screening necessitate further confirmation.
When a sample appears presumptively positive during Screening, additional hair from the original specimen is used for Extraction. Here, drugs are extracted from hair at a much lower concentration compared to other methodologies (e.g., urine or oral fluid), explaining why hair drug screening is the most complex to execute.
Confirmation of positive Screening results is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample undergoes washing before confirmation if necessary. The entire process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
