Hair analysis is recognized as an effective method for detecting alcohol and drug consumption. Hair collects a long-term record of substance use by embedding biomarkers within the fibers of the hair strand as it grows. With samples taken near the scalp, one can identify alcohol and drug use within approximately a 3-month time frame. Collecting hair is straightforward, tampering is relatively challenging, and it can be easily transported.
A 1.5-inch lock consisting of around 200 hair strands (approximating the girth of a #2 pencil) from the closest proximity to the scalp yields 100mg, which is the optimal sample for both screening and confirmation. For EtG, additional panels, or tests exceeding 10 panels, it is suggested to collect 150mg of hair. We suggest using a jeweler’s scale to measure the sample. Should scalp hair be inaccessible, an equivalent volume of body hair may be obtained. Head hair refers exclusively to scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The laboratory procedure for processing drug test results comprises four essential phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed into the laboratory’s records. This step ensures the sample is properly sealed and shipped, assigns it a unique LAN (Laboratory Accessioning Number), and completes any supplementary data entry that is not covered by an electronic chain of custody process.
Screening performs a preliminary assessment for illicit drugs. Although Screening offers a cost-efficient measure to discard drug use in most cases, a positive outcome requires verification to be legally valid. Samples showing presumptive positives in Screening necessitate secondary confirmation.
In instances of presumptive positives during Screening, additional hair is derived from the original sample and prepped for Extraction. In this phase, substances are isolated from hair at a much reduced concentration than through other techniques (e.g., urine or oral fluid), explaining why hair drug analysis is the most intricate method to carry out.
Any positive result from Screening is verified through GC/MS, GC/MS/MS, or LC/MS/MS. Each presumptive positive sample is cleansed prior to confirmation as necessary. The whole laboratory procedure, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: The term "hair follicle tests" is commonly used, yet the examination targets the hair strand, not the underlying follicle.
