Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. The strands retain biomarkers during growth, offering an extended timeline of substance use when collected near the scalp, identifying usage over an estimated period of three months. Hair is straightforward to gather, challenging to tamper with, and easy to send for analysis.
A sample measuring 1.5 inches, consisting of approximately 200 strands (around the diameter of a #2 pencil) nearest to the scalp, yields 100mg, the perfect amount for screening and confirmation tests. For EtG, additional tests, and those exceeding 10 panels, a sample of 150mg is advised. It’s best to weigh the sample using a jeweler's scale. Should scalp hair be unobtainable, a similar quantity of body hair can be used. References to head hair mean scalp hair exclusively, while body hair encompasses all other types such as facial and axillary hair.
Process Overview
The key phases of processing drug test results in a lab include Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the sample enters the lab system, ensuring it was sealed and shipped correctly, a random LAN (Laboratory Accessioning Number) is assigned, and any extra data entry not captured by an electronic chain of custody is completed.
Screening is an initial rapid assessment for abused substances. While it provides a cost-effective method to indicate drug usage for most samples, a positive result needs confirmation to be valid in court, thus requiring secondary confirmation for presumptively positive samples.
When Screening indicates a presumptive positive, more hair is extracted from the original sample and set up for Extraction. In Extraction, drugs are drawn out from hair at significantly lower concentrations compared to other methods like urine or oral fluid, making hair drug testing one of the most challenging techniques.
Any positive results from Screening are confirmed using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation if necessary. The entire procedure from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
