Recognized as an insightful mechanism, hair testing is utilized for identifying drug and alcohol consumption. Hair can encapsulate a prolonged timeline of substance intake by embedding biomarkers within the fibers of the growing strand. When collected close to the scalp, it can offer a maximum detection period of about three months for substances like alcohol. The process of collection is straightforward, challenging to tamper with, and convenient for transportation.
Obtaining a 1.5-inch sample comprising roughly 200 hair strands (akin to the thickness of a #2 pencil) near the scalp results in 100mg of hair, which is the optimal quantity for both screening and confirmation. For EtG, add-ons, or tests comprising over 10 panels, a specimen amount of 150mg is advisable. It's recommended to use a jeweler’s scale for weighing the sample. In cases where scalp hair is unavailable, an equivalent quantity of body hair can be collected. References to head hair pertain solely to scalp hair, whereas body hair mentions all other types (like facial or axillary hair).
Process Overview
The primary phases in the lab processing of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the preliminary sample processing within a lab's database. This includes confirming the sample's sealing and shipping, allocating a random LAN (Laboratory Accessioning Number), and executing any extra data entry not covered by an electronic chain of custody system.
Screening denotes a preliminary assessment for substance abuse. Although Screening is an economical means to negate drug presence in the bulk of samples, a positive result must be validated for court admissibility. Presumptively positive samples during Screening necessitate further confirmation.
Should a sample test presumptively positive during Screening, additional hair is extracted from the original specimen for the Extraction phase. Here, substances are derived from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), underlining why hair drug screening remains the most challenging to execute.
Confirmation of any positive result from Screening utilizes techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Each presumptively positive sample undergoes washing before confirmation when required. The entire lab procedure, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
