Hair Follicle Drug Testing - Linden, IN

What it is, How it works

Hair testing is recognized as an effective method for uncovering drug and alcohol consumption. Hair captures a detailed history of substances by embedding biomarkers within the strands' fibers. When gathered close to the scalp, it offers a detection window extending up to 3 months for drugs and alcohol. Hair collection is straightforward, challenging to tamper with, and convenient for transportation.

A sample size of 1.5 inches, consisting of about 200 hair strands (comparable to a #2 pencil's width) near the scalp, yields 100mg of hair, the optimal amount for both screening and confirmation. For EtG, additional screenings, and tests exceeding 10 panels, a specimen weight of 150mg is advised. Using a jeweler's scale for measuring the specimen is suggested. If scalp hair isn't available, an equivalent quantity of body hair can be utilized. "Head hair" refers specifically to scalp hair, while "body hair" includes all other types (like facial or axillary hair).

Process Overview

The laboratory processing of drug tests encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the sample's initial intake into the lab's system. This involves checking that the sample was properly sealed and couriered, assigning a random LAN (Laboratory Accessioning Number), and concluding any further data entry absent from an electronic chain of custody system.

Screening serves as a quick preliminary check for drug presence. While it's a budget-friendly approach for detecting drug use in most samples, only a confirmed positive screen holds up in court. Samples returning presumptive positives in Screening necessitate additional confirmation.

For samples with presumptive positive results during Screening, additional hair is extracted from the original specimen for Extraction. This step entails withdrawing drugs from hair at lower concentrations than other methods (such as urine or oral fluid), highlighting the complexity of hair drug screening.

Positive results from screening undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples may be washed before confirmation if needed. The comprehensive laboratory process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug activity up to 90 days, whereas urine tests cover a shorter timeframe.
• Hard to evade: Cheating a hair drug test is notably difficult, leading to more reliable results.
• Offers historical insights: It charts a pattern of drug usage over time, rather than only highlighting recent consumption.

Limitations:

• Cannot detect immediate use: A delay of 5-7 days occurs before drugs become discernible in hair.
• Expense: Hair drug tests tend to be pricier than alternative testing methods.
• Result variability: Factors like hair color and individual hair growth differences may impact the levels of drug metabolites in hair.

Note: Although often termed "hair follicle tests", the analysis targets the hair strand rather than 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.
