Hair examinations are increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures biomarkers within its fibers, offering a prolonged timeline of drug and alcohol history. When procured near the scalp, hair can reveal substance use up to a roughly 90-day period. Collecting hair is straightforward, relatively tamper-resistant, and simple to transport.
A 1.5-inch portion consisting of around 200 hair strands (comparable to a #2 pencil’s thickness) nearest to the scalp yields 100mg, which is perfect for screening and validation. For EtG, additional tests, or tests exceeding 10 panels, a recommendation of 150mg is advised. Utilize a jeweler’s scale to weigh the hair specimen. If scalp hair is absent, the same amount of body hair is acceptable. "Head hair" denotes scalp hair only, whereas "body hair" encompasses other types (facial, axillary, and more).
Process Overview
The laboratory processing of a drug test follows four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step, where the sample is initially processed into the lab’s system. It involves confirming the sample's seal and correct shipment, assigning a LAN (Laboratory Accessioning Number) at random, and finalizing any extra data entry absent from an electronic chain of custody system.
Screening, a preliminary quick assessment for drug presence, is cost-efficient for eliminating drug usage in most samples. However, a positive result during Screening requires confirmation for court admissibility. Presumptively positive samples must undergo a secondary confirmation.
If a sample yields a presumptive positive during Screening, more hair is extracted from the original sample for the Extraction phase. During this stage, drugs are retracted from hair in significantly lower concentrations than other methods (such as urine or oral fluid), hence making hair drug screening the most challenging to execute.
Confirming any positive screening result is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation as necessary. The entire lab process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and accreditation standards of ISO/IEC 17025.

Note: Although often termed as "hair follicle tests," the analysis focuses on the hair strand, not the follicle beneath the scalp.
