As a formidable means for uncovering substance use, hair tests play a significant role. Hair archives a lengthy history of alcohol and drug presence, locking biomarkers within the fibers of its progressively developing strands. When extracted near the scalp, hair offers up to about a three-month detection span for substances, including alcohol. This method of collection is straightforward, tamper-resistant, and convenient for transportation.
Securing a sample measuring 1.5 inches with around 200 hairs (similar to a #2 pencil) from the scalp yields 100mg, the perfect mass for both screening and confirmation. To accommodate EtG, supplementary analyses, and/or screenings beyond 10 panels, 150mg of hair is advisable. Utilizing a jeweler’s scale for weighing the sample is recommended. In circumstances lacking scalp hair, equivalent quantities of body hair may be retrieved. It’s important to note that “head hair” specifically pertains to scalp hair, while “body hair” encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The procedure for analyzing drug test outcomes in a laboratory context encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is concerned with the introductory phase of sample integration into a lab’s system. This procedure ensures the sample’s secure sealing and proper shipment while generating a unique LAN (Laboratory Accessioning Number) and finalizing any omitted data entry not captured by an electronic chain of custody framework.
Screening acts as a preliminary, rapid evaluation for potential drug use. While cost-efficient in discounting drug usage in most cases, any positive screenings must undergo confirmation to hold in legal proceedings. Samples with tentative positive results in Screening necessitate further validation.
Upon an initial positive indication in Screening, additional hair is extracted from the original batch for preparation during the Extraction phase. In this process, hair-derived drug concentrations are extracted at considerably lower levels than other approaches (such as urine or oral fluids), rendering hair drug screening a more sophisticated methodology.
Confirming a positive Screen result is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Every sample generating a potential positive is cleansed before confirmation as required. The entire laboratory procedure, from Accessioning to Confirmation, is scrutinized according to both the CAP (College of American Pathologists) Hair certification and ISO/IEC 17025 accreditation protocols.
Advantages of hair drug testing:
Limitations:
