Hair Follicle Drug Testing - Lake Colorado City, TX

What it is, How it works

Hair testing is now recognized as an effective method for detecting drug and alcohol usage. Hair captures a long-term record of alcohol and drug intake by embedding biomarkers in its fibers as it grows. When taken near the scalp, hair can present a detection period of up to three months for alcohol and other substances. Hair is easy to collect, challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches with roughly 200 hair strands (similar in size to a #2 pencil) nearest the scalp provides about 100mg of hair, which is the ideal sample size for both screening and confirmation. For tests involving EtG, additional substances, or over 10 panels, 150mg of the sample is suggested. Utilizing a jeweler's scale for weighing the specimen is advisable. If scalp hair is not available, a comparable amount of body hair may be used. When referring to head hair, it specifically means scalp hair. Body hair encompasses other hair types (such as facial hair, axillary hair, etc.).

Process Overview

The lab process for determining a drug test result involves four main stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the primary processing of a sample within a lab’s framework. This step ensures the sample was properly sealed and sent, allocates a random Laboratory Accessioning Number (LAN), and completes any supplementary data input not covered by an electronic chain of custody system.

Screening represents an initial rapid examination for drugs of abuse. Although Screening is an economical approach to dismiss drug usage in most samples, a positive screen must be confirmed for court validity. Samples that are presumptively positive in Screening demand a secondary confirmation.

For samples presumptively positive during Screening, additional hair is taken from the primary sample and prepped for Extraction. During this phase, drugs are extracted from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), making hair drug screening a challenging method to execute.

Confirmation of positive screening results is achieved with GC/MS, GC/MS/MS or LC/MS/MS. All samples considered presumptive positive are cleansed before confirmation as necessary. The entire lab process, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair standards and the accreditation for ISO / IEC 17025 requirements.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, contrasting with urine tests that have a more limited detection timeframe.
• Resistance to cheating: It's exceedingly difficult to deceive a hair drug test, enhancing the credibility of the results.
• Historical usage data: It illustrates patterns of drug use across a timeline rather than solely recent consumption.

Limitations:

• Inability to detect recent usage: It generally takes around 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Result variability: Elements like hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: While these are often called "hair follicle tests", the examination focuses on the hair strand, not the follicle below the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle tests to traditional urine testing in Lake Colorado City, TX, the advantages are clear. Hair testing offers superior detection accuracy and boasts a longer detection but also presents a more reliable history of drug use compared to urine tests.

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.
