Hair sampling is recognized as an effective method for identifying drug and alcohol usage. The composition of hair captures biomarkers within the fibers as it grows, offering an extended timeline of substance consumption. When cut near the head, hair can reveal evidence of alcohol and drug use for roughly up to three months. Its collection is straightforward, hard to alter, and simple to transport.
A sample measuring 1.5 inches with around 200 hair strands (approximately the diameter of a #2 pencil) closest to the head yields 100mg, deemed the optimal amount for both screening and confirmation. For EtG, additional requests, or tests exceeding 10 panels, 150mg of hair specimen is suggested. Using a jeweler’s scale is advised for measuring the sample. If head hair is missing, a similar quantity of body hair might be gathered. When addressing head hair, it specifically means scalp hair. Meanwhile, body hair encompasses all other varieties (like facial, axillary, etc.).
Process Overview
The four key phases in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the sample's preliminary processing into the lab system. This process involves ensuring the sample's proper sealing and shipment, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any extra data input missing from an electronic chain of custody system.
Screening provides a preliminary rapid assessment for substance abuse. Although Screening is a cost-efficient method to exclude drug exposure in most samples, a positive result needs confirmation to be court-admissible. Samples presumed positive in Screening necessitate a secondary affirmation.
In cases of a presumptive positive during the Screening phase, additional hair from the initial sample is prepared for Extraction. In this step, substance extraction from hair occurs at a significantly lower concentration than alternative methods (such as urine or oral fluid), highlighting why hair drug screening is a challenging approach.
Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleaned before confirmation if required. The overall laboratory journey, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards.
