Hair assessments are now viewed as an effective means for identifying usage of drugs and alcohol. As hair captures biomarkers within its fibers, it can present a historical record of substance consumption over time. Collecting hair close to the scalp can offer a detection timeframe of up to 3 months for both alcohol and drugs. The process of obtaining hair samples is straightforward, challenging to tamper with, and convenient to dispatch.
A hair sample measuring 1.5 inches, consisting of roughly 200 strands (equivalent to a #2 pencil diameter) near the scalp, yields 100mg of hair—ideal for analysis and verification. For testing like EtG or those exceeding 10 panels, a larger 150mg sample is suggested. It's advisable to measure the sample with a jeweler’s scale. In the absence of scalp hair, a comparable volume of body hair can be used. References to head hair solely indicate scalp hair, whereas body hair refers to other varieties (facial, axillary, etc.).
Process Overview
Laboratory processing of test results comprises four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning kicks off the integration of a sample into a lab’s protocol. It entails confirming seal and shipment integrity, allocating a unique LAN (Laboratory Accessioning Number), and carrying out extra information entry not pre-supplied through electronic custodial systems.
Screening offers a preliminary examination for prohibited substances. Although cost-friendly for excluding drug presence in most samples, any positive display requires corroboration for judicial acceptability. Probable positive outcomes in Screening necessitate additional confirmation.
When probed further due to a preliminary positive in Screening, more hair is extracted from the main sample for the Extraction phase. Here, drugs are isolated from hair at significantly reduced levels compared to methods like urine or oral fluid analyses, establishing hair tests as among the most intricate.
GC/MS, GC/MS/MS, or LC/MS/MS procedures validate positive Screening results. Prior to final verification, all suspect positive samples go through appropriate cleansing. This comprehensive lab work from Accessioning to Confirmation is inspected under CAP (College of American Pathologists) Hair criteria as well as ISO / IEC 17025 accreditation.
