Hair analysis has emerged as an effective mechanism to identify drug and alcohol consumption. Hair acts as a long-term record for alcohol and drugs by encapsulating biomarkers within the fiber of the hair as it grows. Hair sampled from close to the scalp can reveal drug and alcohol usage for approximately up to a 3-month duration. Hair collection is straightforward, relatively resistant to tampering, and convenient for shipping.
A 1.5-inch sample, comprising around 200 hair strands (comparable to the girth of a #2 pencil) from the scalp will provide 100mg of hair, optimal for screening and confirmation. For EtG, additional evaluations, and/or tests exceeding 10 panels, a 150mg specimen is advised. It is recommended to measure the weight of the specimen using a jeweler’s scale. If scalp hair is inaccessible, an equivalent portion of body hair can be utilized. When mentioning head hair, it strictly refers to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The four primary steps in the laboratory analysis of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial phase of incorporating a sample into a laboratory’s system. It includes confirming the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.
Screening encompasses an initial rapid assessment for drugs of abuse. Although Screening is an economical method for excluding drug usage on most samples, a positive screen necessitates confirmation to be valid in court. Any specimens yielding presumptive positive results in Screening demand additional confirmation.
When a sample shows presumptive positivity during the Screening stage, more hair is extracted from the original specimen and made ready for Extraction. During this phase, drugs are retrieved from hair at concentrations significantly lower than other methods (e.g., urine or oral fluid), which accounts for the complexity of performing hair drug screening.
Verification of any positive screening outcome is executed using GC/MS, GC/MS/MS or LC/MS/MS. Prior to confirmation, all presumptive positive samples are cleansed as required. The full laboratory process from Accessioning to Confirmation undergoes assessment under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
