Hair analysis is increasingly recognized as an effective method for identifying the consumption of drugs and alcohol. Hair strands retain biomarkers within their fibers over time, providing a prolonged account of drug and alcohol usage. When hair gathered close to the scalp is used, it can reveal substance consumption within approximately a 3-month period. The collection process for hair is straightforward, it's relatively tamper-resistant, and it's simple to transport.
A hair sample of 1.5 inches containing around 200 hairs (similar in size to a #2 pencil) near the scalp provides an optimal 100mg sample for both screening and confirmation. For enhanced testing such as EtG additions and/or tests beyond the 10-panel level, a 150mg sample is advised. For precise measurement, we suggest using a jeweler’s scale to weigh the specimen. If scalp hair is not available, an alternative can be an equivalent amount of body hair. When mentioning head hair, we are referring specifically to scalp hair. Body hair includes other types such as facial and axillary hair.
Process Overview
The laboratory processing of a drug test result consists of four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial procedure where a sample is entered into the lab’s system. This step ensures the sample was appropriately sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry not managed by an electronic custody system.
Screening conducts an initial rapid test for drug presence. While cost-efficient and effective at ruling out drug usage in most cases, a positive screening requires a follow-up for court admissibility. Any presumptive positive results in Screening necessitate further confirmation.
For samples that show presumptive positives during Screening, additional hair is taken from the primary sample for Extraction. This stage involves removing drugs from the hair at concentrations lower than those required in other methodologies (such as urine or oral fluid tests), which underscores the complexity of performing hair drug testing.
Positive screening confirmation is achieved through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples testing presumptive positive undergo washing prior to confirmation if necessary. From Accessioning to Confirmation, the entire laboratory process aligns with the CAP (College of American Pathologists) Hair standards and maintains compliance with ISO / IEC 17025 accreditation.
