Hair testing is now recognized as an effective method for detecting drug and alcohol usage. Hair retains a prolonged history of substance use by embedding biomarkers within the fibers of the developing hair strand. When taken near the scalp, hair can offer up to about a 3-month detection period for alcohol and other drugs. Hair collection is straightforward, relatively tamper-resistant, and simple to ship.
A 1.5-inch sample consisting of around 200 hair strands (roughly the thickness of a #2 pencil) nearest the scalp yields 100mg, the ideal quantity for both screening and confirmation. For EtG, additional tests, and/or assessments beyond 10 panels, 150mg is advisable. Using a jeweler’s scale for weighing the specimen is recommended. If scalp hair isn’t accessible, a comparable quantity of body hair may be used. By head hair, we mean only scalp hair. Body hair comprises all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four primary procedures: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial processing of a sample into a lab’s system. This step includes confirming the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry absent from an electronic chain of custody system.
Screening performs an initial expedited assessment for drugs of abuse. Though Screening is a cost-effective means to exclude drug usage in most samples, a positive screening result demands confirmation to be court-admissible. Any samples exhibiting a presumptive positive in Screening necessitate a secondary confirmation.
If a sample indicates a presumptive positive during Screening, additional hair is extracted from the original specimen and readied for Extraction. During this phase, drugs are isolated from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.
Confirmation of any positive screening outcome is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as necessary. The complete lab process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Despite often being called "hair follicle tests", the analysis actually examines the hair strand rather than the hair follicle beneath the scalp.
