Hair analysis has emerged as an effective method for identifying the usage of drugs and alcohol. Hair encapsulates a prolonged history of substance use by embedding biomarkers within the growing strands. When hair is taken near the scalp, it offers a detection period of up to three months for drugs and alcohol. Hair collection is straightforward, relatively tamper-proof, and simple to transport.
A sample measuring 1.5 inches consisting of approximately 200 strands (the approximate thickness of a #2 pencil) closest to the scalp yields 100mg of hair, which is optimal for screening and confirmation. For EtG, additional tests, or panels exceeding 10, a 150mg sample is preferred. It's advisable to measure the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent amount of body hair may be used. When we mention head hair, it specifically refers to scalp hair. In contrast, body hair includes all other types (facial, axillary, etc.).
Process Overview
The core stages in laboratory processing for a drug test result entail Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step of incorporating a sample into a laboratory’s system. This process ensures the sample was correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any remaining data entry not handled by an electronic chain of custody.
Screening serves as an initial rapid assessment for drug substances. Although Screening is cost-efficient for excluding drug use in most samples, positive results necessitate confirmation for legal acceptability. Samples showing presumptive positives during Screening require further validation.
Should a sample test presumptively positive during Screening, additional hair from the initial batch is extracted for further testing. The Extraction stage involves isolating drugs from hair at concentrations significantly lower than those found in urine or saliva tests, which accounts for the complexity of hair drug testing.
Confirmation of positive Screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS technologies. Presumptive positive samples undergo washing before confirmation as needed. The complete lab procedure from Accessioning through Confirmation is inspected according to CAP (College of American Pathologists) Hair designation alongside ISO/IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Despite being called "hair follicle tests", the analysis focuses on the hair strand, excluding the follicle beneath the scalp.
