Utilizing hair testing stands out as an effective method for detecting the use of drugs and alcohol. Hair serves as a long-term repository for the history of substance use by capturing biomarkers within the strands of growing hair. When sourced near the scalp, hair can reveal a detection period spanning up to roughly 3 months for alcohol and other substances. Collecting hair is straightforward, relatively resistant to tampering, and convenient to transport.
A sample measuring 1.5 inches from around 200 hair strands (comparable to the width of a #2 pencil) near the scalp will yield 100mg of hair, which is the optimal quantity for both screening and confirmation. For EtG tests, additional analyses, and/or tests exceeding 10 panels, a sample of 150mg is preferred. It is advisable to weigh the sample using a jeweler’s scale. If scalp hair is inaccessible, a comparable amount of body hair can be taken. Reference to head hair pertains solely to scalp hair, whereas body hair includes all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory processing of a hair drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the laboratory’s system. This stage includes confirming the integrity of the sample’s seal and shipment, allocating a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry that isn’t covered by an electronic chain of custody system.
Within Screening, an initial and rapid assessment is performed for drugs of abuse. Although Screening affords a cost-effective measure for excluding drug usage in the majority of samples, a positive outcome necessitates confirmation to be viable in legal settings. All samples showing a presumptive positive result require further verification.
Should a sample demonstrate a presumptive positive during Screening, additional hair is extracted from the initial sample and set aside for Extraction. In this phase, drugs are isolated from hair at a markedly lower concentration compared to other methods (such as urine or oral fluids), which renders hair drug screening one of the most challenging techniques to administer.
Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples with presumptive positive results are cleansed before the confirmation process as necessary. The entire laboratory procedure from Accessioning to Confirmation is undertaken with adherence to both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
