Hair Follicle Drug Testing - Ramseur, NC

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair captures a comprehensive timeline of alcohol and drugs by embedding biomarkers within the fibers of the hair strand as it grows. When gathered near the scalp, hair can reveal up to a 3-month detection timeframe for alcohol and other substances. Hair is straightforward to gather, relatively tough to tamper with, and convenient to transport.

A 1.5-inch segment encompassing around 200 hair strands (akin to the size of a #2 pencil) nearest to the scalp will supply 100mg of hair, the optimal sample for both screening and confirmation. For EtG, add-ons, and/or tests beyond 10 panels, a recommendation of 150mg of the sample is given. Using a jeweler’s scale is suggested for weighing the sample. In the absence of scalp hair, an equivalent amount of body hair may be obtained. Specifically, when we mention head hair, we mean only scalp hair. In contrast, body hair includes all other types (facial, axillary, etc.).

Process Overview

The four primary stages in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning comprises the initial intake of a sample into a laboratory’s systems. This process checks that the sample was appropriately sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data input not included in an electronic chain of custody system.

Screening serves as an initial rapid assessment for illicit drug presence. Although Screening is a cost-efficient manner to eliminate drug usage in most samples, a positive screen must be verified to be considered valid in legal settings. Any specimens that show presumptive positives during Screening require a confirmatory analysis.

For samples indicated as presumptive positives in Screening, additional hair is drawn from the initial sample and readied for Extraction. During this phase, drugs are separated from hair at significantly lower concentrations compared to other testing methods (such as urine or oral fluid), which accounts for the complexity of conducting hair drug screening.

Confirming any positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples with presumptive positives are cleansed prior to confirmation as necessary. From Accessioning to Confirmation, the full laboratory procedure is scrutinized in line with the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have comparatively shorter detection periods.
• Challenging to deceive: It is exceedingly challenging to evade a hair drug test, reinforcing the accuracy of the results.
• Delivers historical context: It can illustrate a pattern of drug consumption over time, extending beyond just recent usage.

Limitations:

• Incapable of detecting recent use: It requires about 5-7 days for drugs to become traceable within the hair.
• Higher expenses: Hair drug tests usually incur greater costs compared to alternate drug testing methodologies.
• Result variability: Elements like hair color or personal discrepancies in hair growth can influence the concentration of drug byproducts in the hair.

Note: Commonly termed "hair follicle tests", the examination actually analyzes the hair strand rather than the hair 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.
