Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair can capture a prolonged record of alcohol and drug presence by storing biomarkers within the strands of growing hair. When acquired near the scalp, hair might offer nearly a 3-month detection span for alcohol and drugs. Hair is easy to collect, challenging to tamper with, and convenient to ship.
A 1.5-inch segment of around 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp supplies 100mg of hair, which is the optimal sample amount for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen weight of 150mg is advised. Utilizing a jeweler’s scale to weigh the specimen is recommended. If scalp hair cannot be obtained, a similar quantity of body hair can be used. The term head hair specifically refers to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The key stages in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial processing of a sample within a lab’s system. This step verifies that the sample was appropriately sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and concludes any extra data entry absent from an electronic chain of custody system.
Screening constitutes an initial rapid inspection for drugs of abuse. Although Screening offers a cost-effective way to dismiss drug usage in many samples, a positive screen must be confirmed for court admissibility. Any samples presumptively positive in Screening must undergo secondary confirmation.
If a sample shows presumptive positivity in the Screening phase, additional hair is extracted from the initial specimen and readied for Extraction. In this phase, drugs are retrieved from hair at much reduced concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug screening is one of the most challenging methodologies to execute.
Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS or LC/MS/MS techniques. All presumptive positive samples are cleansed before confirmation as required. The complete laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
