Hair Follicle Drug Testing - Perry, LA

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair can capture a historical record of substances, including alcohol, by preserving biomarkers in the strands as they grow. Hair taken near the scalp can offer an approximate 3-month detection timeframe for alcohol and other drugs. The collection of hair samples is straightforward, tends to resist tampering, and is easy to transport.

A sample of 1.5 inches with around 200 hair strands (comparable to a #2 pencil) near the scalp provides 100 mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional tests, and/or examinations exceeding 10 panels, a 150 mg specimen is suggested. It's advisable to weigh the specimen using a jeweler's scale. If scalp hair isn't available, a proportionate quantity of body hair may be used. When mentioning head hair, we imply scalp hair exclusively. Body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the entry-level handling of a sample within a laboratory's system. This step includes verifying the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.

Screening constitutes an initial rapid examination for substances of abuse. While Screening is a cost-efficient method for ruling out drug use in most samples, any positive screen must be confirmed for court admissibility. Samples presumptively positive in Screening require further verification.

If a sample tests presumptively positive during Screening, additional hair is extracted from the original sample and readied for Extraction. During this process, drugs are extracted from hair at significantly lower concentrations compared to other methodologies (e.g., urine or oral fluid), which challenges hair drug screening as a complex methodology to execute.

Confirmation of any positive screening result is accomplished via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, presumptive positive samples undergo washing as needed. The comprehensive laboratory process, ranging from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests can identify drug use spanning up to 90 days, whereas urine tests have a more limited detection timeframe.
• Challenging to manipulate: Cheating on a hair drug test is very difficult, enhancing result accuracy.
• Supplies historical insights: It can reveal a pattern of substance use over time, beyond just recent activity.

Limitations:

• Incapable of detecting recent use: Detection of drugs in hair takes approximately 5-7 days.
• Expense: Hair drug tests typically incur higher costs than alternative drug testing methods.
• Result variability: Aspects like hair color and individual growth differences can impact the concentration of drug metabolites in hair.

Note: Commonly termed "hair follicle tests", the test actually evaluates 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.
