Hair Follicle Drug Testing - Iron Gate, VA

What it is, How it works

Hair testing has acquired recognition as an effective instrument for identifying drug and alcohol consumption. Hair strands can encase biomarkers within their fibers, thus providing an extended overview of alcohol and drug usage. Collected near the scalp, such samples can offer a detection period of up to around three months for alcohol and drugs. Hair is easy to collect, comparatively tough to tamper with, and straightforward to transport.

A 1.5-inch sample comprising roughly 200 hair strands (approximating the thickness of a #2 pencil) taken nearest to the scalp yields approximately 100mg of hair, which is the optimum amount for screening and verification. For EtG, additional tests, or panels exceeding 10, 150mg of the sample is advised. It's suggested to measure the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent volume of body hair can be taken. When mentioning head hair, it refers exclusively to scalp hair. Body hair denotes all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary stage where a sample is entered into the laboratory’s system. This step ensures the sample is sealed and dispatched correctly, assigns a random LAN (Laboratory Accessioning Number), and addresses any further data entry not accounted for by an automated chain of custody system.

Screening comprises an initial rapid test for drugs of abuse. While Screening offers an economical means to dismiss drug use in most cases, any positive Screening must be validated to stand up in court. Samples that are presumed positive in Screening need another validation test.

If a sample is provisionally positive during Screening, additional hair is extracted from the original sample for the Extraction stage. At this point, drugs are drawn out from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), rendering hair drug screening the most complex methodology to conduct.

The Confirmation of positive screening results is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Samples initially deemed positive are cleaned before confirmation if necessary. The entire laboratory procedure, from Accessioning to Confirmation, undergoes review under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests ascertain drug use for a period reaching 90 days, unlike urine tests which have a shorter detection span.
• Challenging to alter: Hair drug tests are remarkably challenging to manipulate, lending greater accuracy to results.
• Provides longitudinal data: They can outline a trajectory of drug use over time, not limited to recent consumption.

Limitations:

• Cannot identify recent consumption: Drugs require about 5-7 days to be discernible in hair.
• Expense: Hair drug tests generally incur higher costs than other drug testing methods.
• Variability in results: Elements such as hair coloration and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: Commonly termed as "hair follicle tests", the analysis actually examines 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.

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.
