Hair testing has emerged as an effective method for identifying drug and alcohol use. The hair traps biomarkers within its fibers as it grows, providing a comprehensive historical record of substance use. When collected near the scalp, it can reveal alcohol and drug use for a period of up to three months. The collection process is straightforward, and the samples are challenging to tamper with, plus they are convenient to transport.
To obtain the optimal sample for analysis and confirmation, a 1.5-inch section consisting of roughly 200 hair strands (similar to the diameter of a #2 pencil) should be taken from the scalp, yielding approximately 100mg of hair. For tests such as EtG, additional analysis, and/or above 10 panels, a sample of 150mg is advised. We suggest using a jeweler's scale for accurate measurement. If scalp hair is not available, a comparable quantity of body hair can be used. The term "head hair" specifically refers to scalp hair, while "body hair" encompasses all other hair types (including facial and axillary hair).
Process Overview
The laboratory processing of a drug test encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially entered into the laboratory system, ensuring proper sealing and transportation, allocating a unique LAN (Laboratory Accessioning Number), and performing any necessary data entry not captured by an electronic chain of custody system.
Screening conducts a preliminary examination for substances of abuse. While it is an economical approach to eliminate drug use suspicion for a majority of samples, confirmation is essential for any positive result to stand in legal proceedings. Presumptive positive results from Screening require further confirmation.
In cases of presumptive positives during the Screening phase, additional hair from the original sample is processed for Extraction. Drugs are extracted from hair at lower concentrations compared to other methods (such as urine or oral fluid), which is why hair drug analysis demands expert technique.
To substantiate any positive Screening outcome, GC/MS, GC/MS/MS, or LC/MS/MS techniques are employed. All presumptive positives go through a wash process before Confirmation if essential. The comprehensive laboratory workflow from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
