Hair testing is acknowledged as an effective means for identifying drug and alcohol consumption. Hair captures biomarkers within the fibers of the hair strand as it grows, offering a long-term record of substance use. When sourced near the scalp, hair can indicate drug or alcohol use over a span of up to three months. Its simplicity in collection, resistance to tampering, and ease of transportation make hair testing advantageous.
A sample measuring 1.5 inches with approximately 200 hair strands (comparable to the width of a #2 pencil) near the scalp yields 100mg of hair, which is deemed optimal for analysis and verification. For EtG, additional checks, or panels exceeding 10, a 150mg sample is advisable. It's suggested to weigh the hair using a jeweler’s scale. If scalp hair is inaccessible, an equivalent volume of body hair can be taken. References to head hair specifically mean scalp hair. Body hair encompasses all other types, such as facial and axillary hair.
Process Overview
The comprehensive process in laboratory analysis for a drug test result includes Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, a sample is initially processed within the laboratory’s framework, ensuring correct sealing and ship, generating a unique LAN (Laboratory Accessioning Number), and completing necessary data input absent from an electronic custody chain system.
Screening provides an initial assessment for detecting drug misuse cost-effectively. Despite this, any positive outcomes from screening must undergo confirmation to be court-credible. Presumptive positives in screening require a subsequent verification.
When a sample tests as presumptively positive during Screening, more hair will be reclaimed from the existing sample for Extraction. This involves extracting drugs from hair at concentrations notably lower than those in methods like urine or oral fluid tests. This complexity lends hair testing its reputation as the most intricate method to perform.
Confirmation of positive results from screening is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating a presumptive positive undergo cleaning as required before confirmation. The entire laboratory procedure, from Accessioning through Confirmation, is subjected to scrutiny under the CAP (College of American Pathologists) Hair accreditation, alongside ISO / IEC 17025 standards certification.
Advantages of hair drug testing:
Limitations:
Note: Although often termed as "hair follicle tests", the analysis involves the hair strand itself, not the follicle below the scalp.
