Utilizing hair testing has emerged as an effective means to identify drug and alcohol consumption. Hair offers an extended timeline for detecting alcohol and other substances by capturing biomarkers within the strands of hair as they develop. When hair is collected near the scalp, it can reflect substance usage for up to roughly three months. This method is straightforward to collect, relatively resistant to tampering, and convenient to transport.
A sample of hair measuring 1.5 inches, consisting of around 200 strands (roughly the thickness of a #2 pencil) nearest to the scalp, yields 100mg, which is optimal for analysis and verification. For EtG, additional tests, or tests exceeding 10 panels, 150mg of the specimen is advised. Using a jeweler's scale is suggested to measure the sample. Should scalp hair not be available, a proportional amount of body hair is a suitable substitute. References to head hair pertain exclusively to scalp hair. The term "body hair" encompasses all other types (facial, axillary, and so on).
Process Overview
The laboratory evaluation of a drug test involves four principal phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial entry of the sample onto a lab’s records. This comprises confirming whether the sample was sealed and dispatched correctly, assigning a unique LAN (Laboratory Accessioning Number), and fulfilling any outstanding data entry not supplied by an electronic chain of custody process.
Screening initiates by swiftly checking for substances of abuse. Although Screening effectively eliminates drug use in most samples, any indication of drug detection necessitates a confirmation to be legally acceptable. Samples showing presumptive positives during Screening require a second confirmation.
In instances where a sample is suspected positive during Screening, additional hair is extracted from the original sample for Extraction. Here, the concentration of substances extracted from hair is considerably lower than with other techniques (e.g., urine or oral fluid), making hair drug testing one of the most challenging methods.
Positive screening findings undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before Confirmation as necessary. The lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
