Hair Follicle Drug Testing - Leeville, LA

What it is, How it works

Hair analysis is now acknowledged as a potent method for detecting alcohol and drug consumption. Hair encapsulates a prolonged timeline of substance usage by embedding biomarkers within the strands. When snapped close to the scalp, it can reveal up to a 90-day window of drug and alcohol intake. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.

A 1.5-inch fragment of approximately 200 hairs (roughly the dimensions of a #2 pencil) nearest to the scalp yields 100mg, which is optimal for analysis and verification. For EtG and comprehensive tests exceeding 10 panels, 150mg of hair is advisable. It's suggested to measure the hair on a jeweler’s scale. If scalp hair isn't available, a comparable quantity of body hair can be used. "Head hair" specifically pertains to scalp hair. "Body hair" includes all other types (beard, armpit, etc.).

Process Overview

The core steps in processing a lab drug test are Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial recording of a sample within a lab's framework. This stage ensures the sample's packaging and dispatch were intact, assigns a LAN (Laboratory Accessioning Number) at random, and completes any extra data omissions from an electronic custody system.

Screening involves a preliminary swift assessment for narcotics. Though Screening economically dismisses drug presence in most cases, court-valid samples require secondary verification if initial results are positive.

Presumptive positives in Screening undergo further hair withdrawal and preparation for Extraction. During this phase, drugs are isolated from hair at lower densities than alternative methods (such as urine or oral fluid), rendering hair drug analysis technically demanding.

Confirmation of Screening positives is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All tentative positive specimens are cleansed prior to confirmation as deemed necessary. The entirety of the lab process from Accessioning to Confirmation is assessed in compliance with the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug assays can reveal drug intake over a 90-day span, unlike urine tests that offer a shorter timeframe.
• Cheating deterrence: Cheating a hair drug test proves highly arduous, ensuring greater accuracy in results.
• Historical insight: It offers a timeline of drug usage over an extended duration, rather than merely current consumption.

Limitations:

• Recent intake detection: Drugs take about 5-7 days to appear in hair.
• Expense: Hair drug analysis tends to incur higher costs than other drug testing methods.
• Result variability: Elements like hair color and individual hair growth rates can influence drug metabolite concentrations in hair.

Note: Although often labeled "hair follicle tests", the assessment targets the hair shaft, not the follicle itself 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.
