Hair testing is recognized as a significant method for tracking drug and alcohol consumption. Hair offers an extensive history of drug and alcohol use by encasing biomarkers within the structure of the growing hair strand. When gathered near the scalp, hair can provide an approximate 3-month detection window for substances. It's easy to collect, challenging to tamper with, and simple to send.
A 1.5-inch segment consisting of around 200 hair strands (similar in size to a #2 pencil) nearest the scalp provides 100mg of hair, constituting the optimal amount for screening and verification. For EtG, add-ons, and/or analyses exceeding 10 panels, 150mg of the sample is advisable. It's suggested to weigh the sample on a jeweler’s scale. If scalp hair is not available, a comparable amount of body hair may be gathered. When we talk about head hair, we mean scalp hair specifically. Body hair includes all other forms (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test undergoes four main phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning denotes the initial integration of a sample into a lab’s records. This step involves confirming that the sample was properly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.
Screening performs an initial rapid assessment for substances of abuse. Though Screening is an economical approach to exclude substance use in most samples, a positive screen necessitates confirmation for court admissibility. Samples detected as presumptively positive in Screening must undergo secondary confirmation.
Should a sample appear presumptively positive during Screening, further hair is taken from the original sample and prepped for Extraction. Drugs are extracted from hair at much lower levels than in alternate methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.
Confirmation of any positive screens is carried out using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. All samples testing presumptively positive are thoroughly washed before confirmation as required. The comprehensive laboratory workflow from Accessioning to Confirmation is reviewed under the CAP (College of American Pathologists) Hair designation and with ISO / IEC 17025 accreditation.
