Hair Follicle Drug Testing - Lautz, TX

What it is, How it works

Hair analysis is recognized as a potent technique for identifying drug and alcohol consumption. Hair retains a comprehensive history of substance use by capturing biomarkers within its fibers. When extracted near the scalp, hair can indicate substance use within a detection period of up to roughly 90 days for alcohol and drugs. Hair is straightforward to gather, relatively hard to tamper with, and convenient to transport.

A hair sample of 1.5 inches, comprising around 200 hairs (similar in size to a #2 pencil) nearest to the scalp, will yield 100mg of hair, the optimal amount for screening and verification. For EtG, additional tests, and/or panels exceeding 10, a specimen of 150mg is suggested. Utilizing a jeweler's scale to measure the sample is advisable. If scalp hair isn’t available, an equivalent volume of body hair might be used. "Head hair" refers specifically to scalp hair. "Body hair" encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

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

Accessioning comprises the initial administration of a sample into a lab system. This process involves confirming the sample’s sealed and proper shipment, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not provided by an electronic chain of custody system.

Screening provides an initial rapid check for drugs of abuse. Screening is a cost-efficient method to negate drug use in most samples, yet a positive screening demands confirmation to stand in legal proceedings. Specimens that test positive in Screening need a subsequent confirmation.

If a sample exhibits a presumptive positive at the Screening level, more hair is retrieved from the original sample for Extraction. During this phase, drugs are derived from hair at a considerably lower concentration than found in other methods (e.g., urine or oral fluid), marking hair drug screening as the most challenging technique to execute.

Confirming a positive screening outcome is carried out through GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation as necessary. The entire laboratory procedure from Accessioning to Confirmation is examined according to both the CAP (College of American Pathologists) Hair category and in adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug assessments can identify drug usage for up to 90 days, compared to urine assessments with a briefer detection range.
• High resistance to fraud: Cheating a hair drug assessment is notably challenging, enhancing the reliability of the outcomes.
• Yields historical insights: It offers insight into a pattern of substance use over a prolonged period, not just immediate consumption.

Limitations:

• Incapable of determining recent use: Drugs become detectable in hair after an estimated period of 5-7 days.
• Expense: Hair drug assessments are generally pricier than alternative testing approaches.
• Result variability: Elements such as hair color and individual hair growth variations can influence drug metabolite concentration in the hair.

Note: The so-called "hair follicle tests" actually analyze the hair shaft and not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle tests to traditional urine tests in Lautz, TX, the benefits are substantial. Hair tests boast superior detection accuracy, revealing drug use over an extended period.

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.
