Hair Follicle Drug Testing - North Hodge, LA

What it is, How it works

Hair testing is recognized as a significant method for identifying drug and alcohol consumption. It offers an extensive timeline of alcohol and drug use by embedding biomarkers within the strands of hair as it grows. When sampling close to the scalp, it can reflect a detection window of up to roughly 3 months for both alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.

A 1.5-inch section containing around 200 strands of hair (approximately matching the diameter of a #2 pencil) near the scalp yields 100mg, which is the standard amount for analysis and validation. For EtG, extra checks, and/or analyses surpassing 10 panels, a specimen mass of 150mg is advised. It is advisable to weigh the sample using a jeweler's scale. In cases where scalp hair is absent, an equivalent quantity of body hair can be obtained. When mentioning head hair, this indicates scalp hair exclusively. Body hair includes all other hair types (such as facial, axillary, etc.).

Process Overview

An analysis of a drug test result in the lab encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the introductory management of a sample into the lab’s framework. It verifies the sample’s proper sealing and shipping, allocates a random LAN (Laboratory Accessioning Number), and finalizes any extra data entry absent from an electronic chain of custody system.

Screening features a preliminary rapid assessment for drug misuse. Although cost-efficient for excluding drug use in most samples, a positive screen necessitates confirmation to be valid in a legal setting. Samples that screen positive initially require a follow-up confirmation.

Should a sample indicate positivity during Screening, additional hair is retrieved from the original sample for Extraction. Drugs are isolated from hair with lower concentration levels compared to other methods (such as urine or oral fluid), which contributes to hair drug screening's complexity.

Confirming any positive screening outcome happens via GC/MS, GC/MS/MS or LC/MS/MS. All samples that are positive initially undergo washing before confirmation when necessary. The entire process from Accessioning to Confirmation is conducted under CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 certification.

Advantages of hair drug testing:

• Prolonged detection period: Hair tests can reveal drug use up to 90 days back, whereas urine tests offer a briefer detection timeframe.
• Challenging to evade: It's exceedingly tough to deceive a hair drug test, making results more dependable.
• Delivers historical insights: It offers a usage trend over time, rather than just recent intake.

Limitations:

• Lacks recent use detection ability: It typically takes 5-7 days for substances to appear in hair.
• Expense: Hair tests generally incur higher costs than alternative testing techniques.
• Result variability: Factors like hair color and personal differences in hair growth can influence drug metabolite levels in hair.

Note: Commonly termed as "hair follicle tests", the procedure analyzes the hair strand and not the follicle underneath 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.
