The utilization of hair testing has earned recognition as an effective means for identifying drug and alcohol usage. Hair offers an extended timeline of substance history by encapsulating biomarkers within the fibers of the elongating hair strand. When taken near the scalp, hair can yield a detection span of up to roughly 3 months for alcohol and other substances. The collection process for hair is straightforward, challenging to tamper with, and convenient to send.
A 1.5-inch segment consisting of approximately 200 hair strands (akin to the thickness of a #2 pencil) situated closest to the scalp delivers 100mg of hair, which is the optimal amount for both screening and confirmation processes. For EtG, add-ons, and/or exams beyond 10 panels, it is advisable to gather 150mg of the sample. It is advisable to measure the sample using a jeweler’s scale. Should scalp hair be inaccessible, an equivalent quantity of body hair can be gathered. When mentioning head hair, we specifically refer to scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).
Process Overview
The key phases in a laboratory's drug test result processing encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial handling of a sample within a laboratory’s system. This step involves checking that the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry omitted by an electronic chain of custody system.
Screening involves a swift initial assessment for drug abuse. While Screening provides a cost-effective method to eliminate drug usage suspicion for the majority of samples, a positive screen result needs confirmation for court admissibility. Any samples that render a presumptive positive during Screening do necessitate a further confirmation process.
In the event a sample shows a presumptive positive in the Screening phase, more hair is extracted from the initial sample and prepared for Extraction. At this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening one of the most complex methodologies.
Confirmation of any positive screening outcomes is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as required. The entire laboratory procedure from Accessioning to Confirmation is assessed in accordance with both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
