Hair testing is recognized for its efficacy in identifying drug and alcohol consumption. By embedding biomarkers within the strands, hair retains a prolonged history of substance use. Collected from the scalp's surface, hair samples can represent substance use over a span of up to three months. The collection process is straightforward, relatively tamper-proof, and convenient for transport.
A sample measuring 1.5 inches, comprising approximately 200 hairs (resembling a #2 pencil's thickness), yields around 100mg—ideal for both initial screening and confirmatory tests. For EtG, extended panels, or tests beyond 10, 150mg of the sample is advisable. It's recommended to assess the sample's weight using a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair can be substituted. Head hair specifically pertains to scalp hair alone, while body hair encompasses other types like facial or axillary hair.
Process Overview
The laboratory procedure for analyzing drug test results encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a lab’s workflow. This stage involves the verification of proper sealing and shipping, the assignment of a random LAN (Laboratory Accessioning Number), and any supplementary data entry not captured by the electronic chain of custody system.
Screening constitutes a preliminary assessment for the presence of drugs. Despite being a cost-efficient technique for ruling out drug use in most samples, any positive screening results must be validated to be legally defensible. Samples that screen presumptively positive warrant a follow-up confirmation.
In instances of presumptive positivity during Screening, additional hair from the initial sample is used for Extraction. This procedure isolates drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), underscoring hair drug testing's complexity.
Confirmation for positive screening results employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positive results undergo washing prior to confirmation when necessary. The complete laboratory process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair specifications and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although commonly termed "hair follicle tests", the analysis targets the strand itself, not the follicle beneath the scalp.
