Hair Follicle Drug Testing - Highland Haven, TX

What it is, How it works

Hair analysis is now recognized as an effective means for identifying drug and alcohol consumption. Hair serves as a long-lasting record of alcohol and drug intake by encapsulating biomarkers in the strands of hair as they continue to grow. When clipped near the scalp, hair offers roughly a 3-month detection span for alcohol and various drugs. Hair is uncomplicated to gather, hard to tamper with, and straightforward to send.

Approximately 1.5 inches of 200 hair strands (around the diameter of a #2 pencil) nearest the scalp will yield 100mg of hair, the optimal amount for both screening and verification. For EtG, additional testing, and/or analyses exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale for specimen weighing. If scalp hair isn't accessible, a similar quantity of body hair can be used. When discussing head hair, we specifically mean scalp hair. Body hair refers to all other types (facial, axillary, and so on).

Process Overview

The four primary phases in laboratory drug test processing are Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the initial handling of a sample into a lab's system. This process includes confirming the sample's proper sealing and shipment, generating a random LAN (Laboratory Accessioning Number), and completing any missing data input not provided by an electronic custody chain system.

Screening includes a preliminary quick evaluation for substance abuse. Although Screening is a cost-effective method to dismiss drug use in most samples, a positive screen requires confirmation for court admissibility. Samples that presumptively test positive during Screening necessitate additional confirmation.

With a presumptive positive outcome in Screening, additional hair is taken from the original sample for Extraction. In this stage, drugs are extracted from hair at lower concentrations than using other methods (like urine or oral fluid), making hair drug screening one of the most challenging methodologies.

Confirmed positive results are verified through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are cleansed before confirmation as necessary. The complete lab process from Accessioning to Confirmation is assessed under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug usage for up to 90 days, whereas urine tests offer a shorter detection period.
• Resistance to falsification: Cheating a hair drug test is particularly challenging, enhancing result accuracy.
• Historical data provision: It can reveal drug use patterns over time, not just recent usage.

Limitations:

• Incapable of detecting recent use: Detection in hair requires about 5-7 days post-drug use.
• Expense: Hair drug tests tend to be pricier than other testing methods.
• Result variability: Differences such as hair color and individual hair growth rates can influence drug metabolite concentration in hair.

Note: Often dubbed as "hair follicle tests", the actual test analyzes the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Highland Haven, TX, hair follicle testing proves superior to urine testing in several ways. With its advanced detection capabilities, hair testing provides a more accurate analysis of substance usage. Traditional urine tests often fall short in tracking long-term drug use, whereas hair tests offer a comprehensive review of substance habits over an extended period, ensuring greater reliability for employers and institutions.

Extended Detection Window

Employers in Highland Haven, TX, benefit from the extended detection window of hair follicle testing, which shows drug use history for up to 90 days. This extended timeframe offers a thorough insight into a person's substance behavior, aiding in making informed decisions. Such a broad examination period is invaluable for a complete understanding of an employee's or candidate's history.

Tamper-Resistant Testing Method

The hair follicle testing method significantly reduces the risk of tampering, delivering unquestionable reliability in Highland Haven, TX. Unlike other testing forms, hair sampling is far less vulnerable to adulteration, ensuring results that stakeholders can trust.

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.
