Hair Follicle Drug Testing - Newellton, LA

What it is, How it works

Hair testing is now regarded as a crucial mechanism for identifying drug and alcohol consumption. It offers an extended timeline by encapsulating biomarkers within the growing hair fiber. When taken near the scalp, hair can reveal a detection window of up to about three months for substances. It's easy to gather, relatively resistant to tampering, and straightforward to transport.

A 1.5-inch hair sample, around 200 strands (comparable to the width of a #2 pencil), near the scalp, yields 100mg—optimal for assessment and verification. For EtG, additional checks, and/or panels exceeding 10, a specimen of 150mg is suggested. It's advisable to measure the sample using a jeweler’s scale. Should scalp hair be lacking, the equivalent amount of body hair can be used. 'Head hair' strictly refers to scalp hair, while 'body hair' includes all other forms (e.g., facial, axillary).

Process Overview

Processing a drug test result in the lab involves four stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary phase where a sample is integrated into the lab’s system. This step ensures the sample's seal and shipment integrity, allocates a unique LAN (Laboratory Accessioning Number), and completes outstanding data entry omitted by an electronic chain of custody.

Screening performs a swift preliminary assessment for substance misuse. While cost-effective for eliminating drug usage in most specimens, any positive findings must be validated for court acceptance. Presumptive positive cases in Screening need confirmatory testing.

For samples flagged as presumptive positive during Screening, additional hair from the initial sample is used for Extraction. Here, substances are extracted from hair at notably low concentrations compared to other methods like urine or oral fluid, making hair drug screening particularly challenging.

Confirmation for a positive Screening result takes place via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with initial positive results undergo washing before confirmation if needed. The entire lab procedure, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug consumption for as long as 90 days, unlike urine tests with shorter detection timelines.
• Resistance to tampering: It’s extremely challenging to falsify hair drug test results, ensuring higher accuracy.
• Tracks usage over time: It reveals patterns of drug use over extended durations, not just recent consumption.

Limitations:

• Incapable of detecting recent usage: Drugs become traceable in hair after about 5-7 days.
• Expense: Hair drug tests are typically pricier compared to other drug-testing techniques.
• Result variability: Hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although commonly called "hair follicle tests", these tests analyze the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
