Hair Follicle Drug Testing - Kaufman, TX

What it is, How it works

Hair examination is recognized as an effective means for identifying substance use, including drugs and alcohol. Hair retains evidence of alcohol and drug use by embedding biomarkers within the hair strand during growth. When sampled near the scalp, hair can capture up to a three-month history of substance consumption. The collection process for hair is straightforward, largely resistant to tampering, and convenient for shipping.

A sample measuring 1.5 inches comprising roughly 200 hair strands (approximately the diameter of a #2 pencil) from near the scalp yields 100mg, which is optimal for initial and confirmatory screenings. For tests involving EtG, additional analysis, and/or those exceeding 10-panel testing, it is advisable to use 150mg of the specimen. Using a jeweler’s scale to weigh the sample is recommended. In the absence of scalp hair, an equivalent amount of body hair can be sourced. The term head hair denotes only scalp hair, whereas body hair encompasses all other variants (such as facial and underarm hair).

Process Overview

The laboratory processing for drug testing encompasses four pivotal phases: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is initially processed into the laboratory’s system, ensuring it was properly sealed and sent, receiving a random LAN (Laboratory Accessioning Number), and addressing any supplementary data entry not covered by an electronic chain of custody system.

Screening acts as a preliminary review for substances of abuse. While it is a cost-efficient method to eliminate drug usage in most samples, a positive screening result must be validated to hold credibility in legal proceedings. Samples presumed positive from Screening will necessitate further confirmation.

Should a sample indicate a presumptive positive during the Screening phase, additional hair is extracted from the original sample and readied for Extraction. In this phase, substances are extracted from hair at a significantly reduced concentration relative to other analyses (e.g., urine or oral fluid), highlighting hair drug screening as a notably challenging procedure.

Confirmation of positive screening outcomes is achieved through GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples with presumptive positive results undergo washing before confirmation, if required. The complete laboratory sequence from Accessioning to Confirmation is scrutinized under the standards of the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can uncover drug usage over up to 90 days, unlike urine tests with shorter detection spans.
• Resistance to tampering: It presents a significant challenge to cheat a hair drug test, enhancing accuracy.
• Historical substance use: It documents patterns of drug usage over time, rather than only recent usage.

Limitations:

• Inability to detect recent use: Substances only become detectable in hair after about 5-7 days.
• Expense: Hair drug testing generally incurs higher costs compared to alternative testing methodologies.
• Variability in outcomes: Elements such as hair color and individual hair growth rates can influence the concentration of drug metabolites in hair.

Note: Though often labeled as "hair follicle tests", the analysis targets the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Kaufman, TX, hair follicle testing has a clear edge over urine testing. Hair tests not only offer a wider detection window but also a higher level of accuracy and reliability. Whilst urine tests excel in detecting very recent substance use, hair testing remains unbeaten in providing historical insights into an individual's drug use for up to 90 days.

Extended Detection Window

One of the standout benefits of hair follicle tests in Kaufman, TX is their extended detection window. With the ability to trace drug use up to 90 days back, employers gain a more detailed understanding of an individual's substance usage. This comprehensive analysis aids in making informed and proper decisions about employee or applicant backgrounds.

Tamper-Resistant Testing Method

Hair follicle drug testing in Kaufman, TX offers unparalleled security against tampering, providing trustworthy results. The very nature of hair testing makes it extremely difficult, if not impossible, to adulterate samples.

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.
