Hair Follicle Drug Testing - Great Barrington, MA

What it is, How it works

Hair testing is recognized as an effective method for identifying alcohol and drug use. Hair can reveal a comprehensive history of substance use by capturing biomarkers within the fibers of the growing hair strand. When samples are taken near the scalp, hair can show drug and alcohol presence over roughly a 3-month period. It is straightforward to collect, challenging to tamper with, and convenient for shipping.

Collecting a 1.5-inch sample of approximately 200 hair strands, equivalent to the thickness of a #2 pencil, close to the scalp yields 100mg of hair, which is the optimal quantity for analysis. For tests like EtG, add-ons, or those exceeding 10 panels, it's suggested to collect 150mg of the sample. We advise using a jeweler's scale to measure the specimen. In the absence of scalp hair, a similar amount of body hair can be obtained. References to head hair pertain solely to scalp hair, while body hair encompasses other variations (facial, axillary, etc.).

Process Overview

The drug test result process in laboratories includes the key steps of Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of integrating a sample into a laboratory’s system. This step entails verifying the proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing additional entries not covered by an electronic chain of custody.

Screening involves a preliminary assessment for drug presence. While it provides a cost-efficient method to exclude drug use in most samples, a screen yielding a positive outcome must be confirmed for legal acceptance. All samples presumed positive in Screening require a second confirmation.

When a sample tests positive at the Screening phase, extra hair is taken from the original sample and prepared for Extraction. In this phase, substances are isolated from hair at lower concentrations compared to other methods (like urine or saliva), making hair drug testing the most challenging method to conduct.

Confirmations for any positive screenings are carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are washed as necessary. The complete lab process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair criteria and in accordance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can uncover drug use up to 90 days back, whereas urine tests offer a shorter validation span.
• Cheating is exceptionally challenging: The accuracy of hair drug tests is heightened due to the difficulty in compromising them.
• Shows historical patterns: Provides insight into drug use patterns over time, rather than just recent usage.

Limitations:

• Inability to detect recent consumption: Drugs take roughly 5-7 days to become detectable in hair strands.
• Expense: Hair drug tests tend to be pricier compared to other testing methods.
• Result variability: Factors like hair color and individual hair growth differences can impact drug metabolite concentrations in hair.

Note: Although often called "hair follicle tests", the analysis is performed on the hair strand itself, 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
