Hair testing is recognized as a formidable instrument for detecting drug and alcohol usage. Hair offers a comprehensive history of alcohol and other substances by embedding biomarkers within the fibers of the hair as it grows. When sampled near the scalp, hair can reveal a detection period extending up to around 3 months for alcohol and other substances. Hair is straightforward to collect, relatively challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches containing roughly 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp will provide 100mg of hair, which is the optimal sample size for testing and confirmation. For EtG, additional tests, and/or analyses exceeding 10 panels, a sample of 150mg is advisable. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair is not accessible, a comparable quantity of body hair can be obtained. When mentioning head hair, we refer solely to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial incorporation of a sample into a laboratory system. This process involves ensuring that the sample was sealed and dispatched appropriately, allocating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data input not covered by an electronic chain of custody system.
Screening consists of a preliminary assessment for the presence of drugs. Even though Screening is a cost-efficient method to exclude drug usage in the majority of specimens, a positive screen requires confirmation to be permissible in court. All samples that show potential positivity in Screening necessitate subsequent confirmation.
If a sample is potentially positive during the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. In this step, drugs are isolated from hair at considerably lower concentrations compared to other methodologies (e.g., urine or oral fluid), which is why hair drug screening is regarded as the most challenging methodology to carry out.
Confirmation of any positive screening output is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo washing prior to confirmation as necessary. The entire laboratory procedure from Accessioning to Confirmation is evaluated within both the CAP (College of American Pathologists) Hair designation and the compliance with ISO / IEC 17025 standards.
