Hair analysis is recognized as an effective method for identifying the consumption of alcohol and drugs. It provides an extended timeline by preserving biomarkers within the hair's growing fibers. When sampled near the scalp, hair can offer a detection period of roughly three months for substances. It is easy to gather, hard to tamper with, and simple to transport.
A 1.5-inch piece containing around 200 hair strands (similar in size to a #2 pencil) that's nearest to the scalp yields 100mg of hair, which is perfect for initial testing and confirmation. For EtG, additional tests, or beyond 10-panel examinations, 150mg is suggested. We advise measuring the hair weight with a jeweler's scale. Should scalp hair be absent, equivalent body hair may be used. Head hair specifies only scalp hair, whereas body hair includes other types (facial, axillary, etc.).
Process Summary
The drug test procedure in a lab comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning begins with entering a sample into a laboratory’s system. This includes checking that the sample is correctly sealed and shipped, assigning a LAN (Laboratory Accessioning Number), and completing any necessary data entry that's not covered by an electronic chain of custody system.
Screening allows for an initial evaluation for drug presence. Although cost-efficient for determining drug usage on most samples, a positive screen must be validated to be acceptable in legal proceedings. Any samples marking as presumptive positive in Screening need a follow-up confirmation.
Once a sample tests presumptive positive in Screening, additional hair from the initial collection is used for Extraction. Here, drugs are retrieved from hair at notably lower levels compared to other methods (like urine or oral fluid), underscoring why hair drug analysis is a challenging technique.
Verification of any positive screen result is undertaken via GC/MS, GC/MS/MS or LC/MS/MS. Before confirmation, all presumptive positive samples are cleaned as necessary. The complete laboratory operation, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation.
