Hair Follicle Drug Testing - Alsen, LA

What it is, How it works

Hair examinations have now become recognized as an effective approach for the identification of substance and alcohol consumption. Hair retains a prolonged history of alcohol and drugs by capturing biomarkers within the fibers of the evolving hair strand. When taken close to the scalp, hair can offer a detection period of up to about 3 months for alcohol and drugs. Hair is straightforward to gather, relatively hard to tamper with, and simple to dispatch.

A section measuring 1.5 inches and comprising roughly 200 hair strands (around the thickness of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the perfect sample for analysis and verification. For EtG additional tests and/or screenings over 10 panels, 150mg of the sample is advised. It is suggested to measure the sample on a jeweler's scale. If scalp hair is not available, a similar quantity of body hair may be used. Head hair pertains solely to scalp hair. Body hair denotes all other hair categories (facial, axillary, etc.).

Process Summary

The primary stages in the laboratory handling of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the preliminary handling of a specimen into a lab's framework. This entails confirming that the sample was properly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent in an electronic chain of custody framework.

Screening involves an initial rapid assessment for drugs of abuse. Though Screening is a more budget-friendly means of eliminating drug usage for the majority of samples, a positive screen must be confirmed for legal admissibility. Any samples marked as presumptively positive in Screening necessitate a secondary confirmation.

In instances where a sample is presumptively positive during the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), which is why hair drug testing is considered the most challenging procedure to execute.

Verification of any positive screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are cleansed prior to confirmation if required. The entire lab procedure from Accessioning to Confirmation undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug assays can identify drug usage for up to 90 days, unlike urine tests which have a restricted detection period.
• Hard to manipulate: Hair drug tests are challenging to circumvent, ensuring more precise outcomes.
• Delivers historical information: It provides a pattern of substance usage over time, not merely recent use.

Drawbacks:

• Incapable of identifying recent use: It takes about 5-7 days for substances to become detectable in hair.
• Expenditure: Hair drug tests typically incur higher costs than alternative drug testing techniques.
• Result variability: Elements such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in hair.

Note: Although often termed "hair follicle tests", the test analyzes the hair strand and 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.
