Hair Follicle Drug Testing - Northeast Brazos, TX

What it is, How it works

Hair testing is recognized as an effective method for identifying the use of alcohol and drugs. Hair strands hold a long-term record of alcohol and drug intake by encasing biomarkers within the strand's fibers. When taken near the scalp, hair can indicate drug and alcohol use for up to roughly three months. Hair samples are easy to collect, less prone to tampering, and straightforward to ship.

A hair sample measuring 1.5 inches and containing about 200 strands (similar to a #2 pencil's thickness) cut close to the scalp gives 100mg of hair, which is ideal for both screening and confirmation tests. For EtG, additional tests, or those exceeding 10 panels, a 150mg sample is preferable. It's advisable to weigh the hair using a jeweler’s scale. If scalp hair is missing, an equivalent quantity of body hair may be used. References to head hair specifically mean scalp hair, while body hair encompasses other types such as facial and axillary.

Process Overview

The key stages in processing a drug test result in the lab include Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, a sample is initially processed into the lab’s system. This step ensures that the sample was sealed and transported correctly, a random LAN (Laboratory Accessioning Number) is assigned, and any further data entry not handled by an electronic chain of custody system is completed.

Screening serves as an early check for substance abuse. While it is a cost-effective strategy to eliminate drug presence in most cases, any positive outcomes require verification for legal admissibility. Samples that screen positive undergo further confirmation.

If a Screening indicates a positive result, more hair is extracted from the original sample for further Extraction. In this process, drugs are isolated from hair in much lower concentrations than with methods like urine or oral fluid tests, making hair drug screening notably challenging.

Confirmation for any positive screen result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, presumptive positive samples are cleansed as necessary. The entire lab operation, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair tests can find drug use up to 90 days in the past, unlike urine tests with shorter detection periods.
• Hard to manipulate: Cheating a hair drug test is quite difficult, increasing accuracy.
• Historical usage patterns: It reveals drug use over time, not only recent consumption.

Limitations:

• Cannot identify recent use: Drugs take around 5-7 days to be detected in hair.
• Expense: Hair drug tests typically cost more than other methods.
• Result variability: Factors such as hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: Despite being called "hair follicle tests", these tests assess the hair strand, not the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Northeast Brazos, TX
In comparison to traditional urine tests, hair follicle testing provides enhanced accuracy and dependability.

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.
