Hair Follicle Drug Testing - Trout Valley, IL

What it is, How it works

Hair testing is increasingly regarded as an effective method for detecting drug and alcohol consumption. Hair offers an extended history of alcohol and drug presence by capturing biomarkers within its growing strands. When acquired near the scalp, hair can reveal up to a 3-month detection period for alcohol and drugs. Collection is straightforward, tampering is challenging, and transportation is convenient.

A 1.5-inch segment of roughly 200 hair strands (about as thick as a #2 pencil) nearest the scalp will produce 100mg of hair, the optimal sample for both screening and confirmation. For EtG, additional tests, and/or panels beyond 10, a 150mg sample is advised. It's suggested to weigh the hair on a jeweler’s scale. If scalp hair can't be collected, an equivalent quantity of body hair is acceptable. "Head hair" specifically refers to scalp hair. "Body hair" encompasses all other hair types (such as facial or axillary hair).

Process Overview

There are four primary stages in lab processing of a drug test: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of integrating a sample into a lab's system. This involves ensuring the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry omitted by an electronic chain of custody system.

Screening entails an initial swift check for drugs of abuse. Though Screening is a cost-efficient strategy to rule out drug usage for most samples, a positive screen must be validated for court admissibility. Any samples that test presumptively positive during Screening need further confirmation.

For samples showing a presumptive positive during Screening, additional hair is taken from the original specimen for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), which makes hair drug testing the most challenging method to conduct.

Confirmation for any positive screen result is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as needed. The complete lab process, from Accessioning to Confirmation, is assessed in line with both the CAP (College of American Pathologists) Hair standards and the accreditation to ISO / IEC 17025 requirements.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests that have a shorter detection timeframe.
• Challenge to deceive: It is exceedingly tough to cheat on a hair drug test, rendering the results more trustworthy.
• Offers historical insight: It provides a pattern of drug usage over time, rather than just recent consumption.

Limitations:

• Cannot detect recent use: It takes about 5-7 days for drugs to become noticeable in hair.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Result variability: Elements like hair color and personal differences in hair growth can influence drug metabolite concentration in hair.

Note: Although often termed "hair follicle tests," the analysis actually involves the hair strand, not the follicle below 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.
