Hair analysis is recognized as an effective method for identifying substance use, including drugs and alcohol. Hair offers a prolonged timeline of substance intake by embedding indicators within the structure of the growing hair strands. When obtained near the scalp, hair can reveal substance presence for a period extending to around three months. The collection process is straightforward, tampering is challenging, and transportation is manageable.
A hair sample of 1.5 inches, consisting of roughly 200 strands (comparable to the diameter of a #2 pencil) nearest the scalp, will provide 100mg, suitable for both screening and verification. For EtG tests and panels exceeding ten, 150mg of the sample is suggested. Measuring the sample with a jeweler's scale is recommended. If scalp hair cannot be acquired, an equivalent quantity of body hair may be used. "Head hair" refers exclusively to scalp hair, whereas "body hair" includes all other hair varieties (like facial, axillary, etc.).
Process Overview
The laboratory handling of drug test samples follows four core steps: Accessioning, Screening, Extraction, and Confirmation.
The Accessioning step involves integrating the sample into the lab's records, ensuring it was properly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data requirements not covered by an electronic chain of custody system.
Screening is a preliminary evaluation to check for drug presence. Although cost-efficient for excluding drug use in most cases, any positive result in the screening phase requires confirmation for legal admissibility. All samples indicating a possible positive result in Screening must undergo further confirmation.
Upon detecting a potential positive in Screening, additional hair is extracted from the original sample for the Extraction phase. This step involves extracting drugs from hair at much lower concentrations compared to other methods (such as urine or oral fluid), making hair drug analysis more complex.
Positive Screening results are validated using GC/MS, GC/MS/MS, or LC/MS/MS. Samples showing potential positives are cleansed before confirmation if needed. The complete lab process from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 certification.
