Hair analysis is recognized as an effective means for detecting drug and alcohol consumption. It archives a comprehensive history of substance use by capturing biomarkers within the strands. When gathered near the scalp, hair samples can deliver a detection period of up to roughly 90 days for substances. Collecting hair is straightforward, fairly tamper-proof, and convenient for transportation.
A sample of 1.5 inches consisting of around 200 hair strands (comparable to a #2 pencil in thickness) taken closest to the scalp yields 100mg, which is the optimal sample size for testing and confirmation. For extended tests, such as EtG, add-ons, or panels exceeding ten, a 150mg specimen is advised. It's recommended to measure the specimen using a jeweler’s scale. If scalp hair is unavailable, an equivalent quantity of body hair is acceptable. References to head hair pertain solely to scalp hair, while body hair encompasses all other types (such as facial and axillary).
Process Overview
The laboratory processing of a drug test result entails four primary stages: Accessioning, Screening, Extraction, and Confirmation.
In the Accessioning stage, the sample enters the lab’s system, which involves checking that the sample was properly sealed and shipped, assigning a randomized LAN (Laboratory Accessioning Number), and finalizing any remaining data entries not covered by an electronic chain of custody.
Screening provides an initial assessment for drugs. Though it is an economical approach to minimize drug presence in most samples, a positive indication necessitates further confirmation for legal admissibility. Any samples with presumptive positive results in Screening must undergo additional confirmation.
In the event of a presumptive positive during Screening, the initial sample is utilized for the Extraction stage. Here, drugs are isolated from hair at lower concentrations compared to other testing methods (such as urine or oral fluid), which makes hair drug testing particularly challenging.
Confirmation follows positive screening results through methods like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo washing before confirmation if required. This complete lab process, from Accessioning to Confirmation, is reviewed under the standards of CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation.
