Hair analysis is now regarded as a potent method for identifying drug and alcohol consumption. Hair captures long-term substance use history by embedding biomarkers within the strands as they grow. When a sample is taken from near the scalp, hair offers about a three-month window for alcohol and drug detection. It is easy to collect, relatively hard to tamper with, and straightforward to ship.
A sample length of 1.5 inches, consisting of roughly 200 hair strands (comparable to the width of a #2 pencil) closest to the scalp, will yield 100mg of hair—this is the ideal quantity for analysis and confirmation. For tests such as EtG, add-ons, or those exceeding 10 panels, a 150mg sample is advised. We suggest using a jeweler's scale for measurement. Should scalp hair be unavailable, an equivalent quantity of body hair can be used. Here, head hair denotes scalp hair specifically, whereas body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four core steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial entry stage of a sample into the lab’s workflow, ensuring the sample’s integrity, assigning a unique LAN (Laboratory Accessioning Number), and handling any data entry not covered by an electronic chain of custody.
Screening involves a preliminary scan for drugs. Although Screening is cost-efficient for ruling out drug use in most samples, a positive result needs confirmation for legal validity. Any sample yielding a presumptive positive during Screening will require a confirmatory procedure.
If a sample indicates a potential positive status in Screening, additional hair is extracted from the original specimen for the Extraction step. Here, drug compounds are isolated from hair at lower concentrations than in urine or oral fluid methods, which makes hair drug screening particularly challenging.
Positive screen results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Samples showing presumptive positives are cleansed before confirmation if necessary. The entire process from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 standards.
