Hair testing is recognized as an effective method for detecting drug and alcohol usage. Hair traps biomarkers within its fibers, offering a long-term history of substance use. When harvested close to the scalp, hair can reveal drug and alcohol consumption within a detection period of up to three months. Collecting hair is straightforward, challenging to tamper with, and simple to send.
A sample measuring 1.5 inches and consisting of approximately 200 strands (akin to a #2 pencil's thickness) near the scalp yields about 100mg—the optimal amount for screening and verification. For EtG, extensions, or tests exceeding ten panels, 150mg of the sample is advisable. We suggest using a jeweler’s scale for weighing the specimen. If scalp hair cannot be sourced, an equivalent volume of body hair may be used. When mentioning head hair, we specifically refer to scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where the laboratory registers the sample in its system. This step involves confirming the proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent in an electronic chain of custody system.
Screening involves a preliminary assessment for drugs of abuse. Although Screening is economically efficient for initially ruling out drug presence in most samples, a confirmed positive screen is necessary for legal admissibility. Samples that are presumptively positive during Screening require secondary validation.
Should a sample test presumptively positive during the Screening phase, additional hair is extracted from the original sample for Extraction. In this phase, drugs are extracted from the hair at significantly lower concentrations compared to other methodologies (e.g., urine or oral fluid), making hair drug screening one of the most challenging methods to execute.
Societal confirmation of any positive screen is achieved through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positive results are cleansed before confirmation when necessary. The complete laboratory procedure, from Accessioning through Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.
