Hair testing is now regarded as a crucial method for identifying drug and alcohol consumption. Hair captures long-term drug and alcohol history by embedding biomarkers within the fibers of the growing hair strand. When sourced close to the scalp, hair can reveal drug and alcohol use across an estimated 3-month time frame. Hair is easy to collect, challenging to tamper with, and convenient to transport.
Collecting a 1.5-inch sample, consisting of about 200 hair strands (roughly the size of a #2 pencil), located nearest to the scalp will yield approximately 100mg of hair, the optimal amount for screen and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen weight of 150mg is advisable. We suggest measuring the specimen with a jeweler's scale. Should scalp hair be unavailable, a comparable amount of body hair can be collected. "Head hair" pertains exclusively to scalp hair. "Body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result is composed of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the sample's preliminary integration into a laboratory's system. It verifies that the sample was correctly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes additional data entry as needed, absent from an electronic chain of custody system.
Screening serves as a preliminary evaluation for drugs of abuse. It offers a cost-effective approach to excluding drug use among the majority of samples; however, a positive screen necessitates confirmation for legal acceptance. All samples presumptively positive in Screening must undergo a secondary confirmation.
Should a sample show a presumptive positive result during Screening, more hair is taken from the initial specimen and prepped for Extraction. In this stage, drugs are extracted from hair at much lower concentrations compared to other methodologies (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.
Confirmation for positive screening results is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation, as required. The entire laboratory process from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.
