Hair Follicle Drug Testing - Occoquan, VA

What it is, How it works

The use of hair testing is recognized as an effective approach for detecting drug and alcohol consumption. Hair serves as a repository for long-term substance use history, capturing biomarkers within the strands as they grow. Collected from the scalp, hair can offer an approximately 3-month window for detecting alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and convenient to transport.

Gathering a 1.5-inch sample of around 200 hair strands (roughly equivalent to a #2 pencil) closest to the scalp provides 100mg, which is ideal for screening and confirmation. For EtG, add-ons, and tests beyond 10 panels, a 150mg sample is advisable. It is suggested to weigh the sample on a jeweler’s scale. If scalp hair cannot be retrieved, a similar amount of body hair can be obtained. 'Head hair' refers specifically to scalp hair. 'Body hair' includes all other types (facial, axillary, etc.).

Process Overview

The laboratory process of drug testing results includes four main steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial lab system entry of the sample, ensuring it was sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry that an electronic chain of custody system has not supplemented.

Screening provides an initial analysis for drugs of abuse. While it is a cost-efficient method for excluding drug use in most samples, a positive result necessitates confirmation for court eligibility. Any samples that are presumptively positive during Screening require a secondary confirmation.

For samples identified as presumptively positive in Screening, additional hair is extracted from the initial sample for the Extraction process. During this stage, drugs are extracted from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Confirmation of any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are pre-washed as needed before confirmation. The comprehensive laboratory procedure, from Accessioning to Confirmation, is subject to review under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can identify substance use for up to 90 days, unlike urine tests which have a briefer detection range.
• Hard to manipulate: Manipulating a hair drug test is highly challenging, enhancing the accuracy of results.
• Historical utilization data: It can reveal a trend of substance use over time, beyond recent usage.

Limitations:

• Inability to detect recent consumption: It requires approximately 5-7 days before drugs become noticeable in hair.
• Expense: Hair drug tests are typically more costly compared to alternative drug testing techniques.
• Result variations: Factors such as hair color and personal variability in hair growth can influence the concentration of drug metabolites found in hair.

Note: Despite frequent references as "hair follicle tests," the analysis is conducted on the hair strand, not the follicle beneath the scalp.

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
