Hair Follicle Drug Testing - Jewett, TX

What it is, How it works

Recognized as a robust method, hair testing efficiently identifies drug and alcohol consumption. It offers an extensive history of substance use by encapsulating biomarkers within the hair's fibers. When collected near the scalp, hair can provide an approximate 3-month detection frame for drugs and alcohol. It is easy to gather, somewhat resistant to tampering, and simple to transport.

Collecting a 1.5-inch segment of about 200 hair strands (comparable to the dimension of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for both screening and confirmation. For EtG, additional tests, and tests beyond 10 panels, a collection of 150mg is advisable. It is recommended to measure the hair on a jeweler’s scale. If scalp hair is unobtainable, an equivalent amount of body hair can be used. The term "head hair" refers specifically to scalp hair, while "body hair" encompasses all other hair types (such as facial and axillary hair).

Process Overview

The laboratory processing for drug test results involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning integrates the sample into the lab’s system initially. This step confirms the proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data entry absent from the electronic chain of custody.

Screening serves as a preliminary check for drug abuse. Though cost-effective for excluding drug usage in most samples, a positive screen necessitates confirmation for court acceptance. Samples with presumptive positive results in Screening require a second confirmation.

Should a sample have a presumptive positive result in Screening, further hair is extracted from the original sample to prepare for Extraction. In this step, drugs are extracted from hair at much lower concentrations than in other methods (like urine or oral fluid), making hair drug screening particularly challenging.

Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned before confirmation when necessary. The whole lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests can ascertain drug usage up to 90 days, compared to the shorter timeframe of urine tests.
• Hard to manipulate: Cheating a hair drug test is notably challenging, thus ensuring result accuracy.
• Traces drug use history: Reflects patterns of drug consumption over time, not merely recent usage.

Limitations:

• No recent use detection: Drugs require about 5-7 days to become detectable in hair.
• Expense: Hair drug tests typically incur higher costs than alternative testing methods.
• Result variability: Factors such as hair color and individual differences in hair growth can influence the level of drug metabolites found in hair.

Note: Though occasionally termed "hair follicle tests", the analysis evaluates the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing boasts several advantages over traditional urine tests in Jewett, TX. Primarily, these tests provide superior detection accuracy and reliability in identifying past drug usage. Where urine tests may fail, hair analysis offers a more holistic view, showcasing consumption patterns over an extended period and thereby supporting stringent drug-free guidelines maintained by employers.

Extended Detection Window

One notable benefit of hair follicle testing in Jewett, TX, is its extensive detection window. Unlike urine tests which offer a brief look into recent use, hair testing examines drug intake over a much larger timeframe, often up to 90 days. This advantage provides a thorough evaluation of an applicant’s or employee’s drug history, enabling more informed employment decisions.

Tamper-Resistant Testing Method

Jewett, TX's hair follicle testing minimizes the potential for sample tampering, ensuring reliability. The method stands as a formidable barrier against adulteration, providing clear, undistorted results. Such integrity in testing backs the employer’s confidence in the accuracy of the data obtained, reinforcing fair and objective employment practices.

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.
