Hair analysis is recognized as an effective strategy for discovering drug and alcohol consumption. Hair captures a prolonged history of substances by embedding markers within the growing strand's fibers. When taken from near the scalp, hair offers up to an estimated 3-month detection timeframe for various substances. Hair is convenient to collect, challenging to tamper with, and straightforward to transport.
A sample of 1.5 inches, approximately 200 strands (equivalent to a #2 pencil's thickness), gathered close to the scalp provides 100mg, which is the ideal amount for initial testing and confirmation. For tests involving EtG, additional tests, or those exceeding ten panels, 150mg is suggested. Using a jeweler’s scale to measure the sample is advisable. If scalp hair isn't accessible, a comparable quantity of body hair can be collected. References to head hair specifically indicate scalp hair. Body hair encompasses all other types (such as facial or axillary hair).
Process Overview
The key four stages in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the primary processing of a sample into the lab’s workflow. This step involves checking that the sample was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any extra data entry not covered by an electronic chain of custody system.
Screening is an initial quick analysis for drug use. While it’s a cost-efficient method to dismiss usage in most samples, a screen yielding a positive result must be confirmed for court acceptability. Samples showing presumptive positives in Screening necessitate secondary verification.
Should Screening suggest a positiva sample, more hair is taken from the original batch and prepared for Extraction. In this phase, drugs are removed from hair in lower concentrations compared to other methods (like urine or oral fluid), making hair drug testing the most challenging procedure.
Confirmed screenings follow through GC/MS, GC/MS/MS, or LC/MS/MS analyses. Any samples indicating presumptive positives undergo cleaning before confirmation if necessary. The comprehensive lab procedure from Accessioning to Confirmation is assessed in alignment with the CAP (College of American Pathologists) Hair guidelines and certification in agreement with ISO / IEC 17025 criteria.
