Hair Follicle Drug Testing - Webb, TX

What it is, How it works

Hair examinations have increasingly been regarded as a formidable instrument for identifying drug and alcohol consumption. Hair possesses the ability to capture a prolonged record of alcohol and other substances by embedding biomarkers within the fibers of the developing hair shaft. When taken near the scalp, hair can reveal a detection period of up to nearly 90 days for alcohol and other substances. Hair collection is straightforward, moderately challenging to tamper with, and convenient to transport.

A 1.5-inch segment comprising roughly 200 hair strands (comparable in size to a #2 pencil) closest to the scalp will produce 100mg of hair, which is the optimal sample for both analysis and confirmation. For EtG, supplementary tests, and/or those exceeding 10 panels, a specimen of 150mg is advisable. It is advised to weigh the specimen using a jeweler’s scale. If scalp hair cannot be obtained, an equivalent volume of body hair may be substituted. The term head hair is used specifically to denote scalp hair. Body hair encompasses all other varieties (beard, underarm, etc.).

Process Overview

The primary four stages involved in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial incorporation of a specimen into a lab’s procedure. This entails confirming that the specimen was properly sealed and transported, allocating a random LAN (Laboratory Accessioning Number), and performing any supplementary data entry absent from an electronic chain of custody system.

Screening pertains to an initial expedited examination for illicit substances. Although Screening is a cost-efficient method to rule out drug consumption in the majority of specimens, a positive screen must be corroborated to be accepted in judicial proceedings. Examples yielding a presumptive positive in Screening necessitate a subsequent verification.

If a specimen registers as presumptively positive during the Screening phase, additional hair is extracted from the original sample for the Extraction process. Here, substances are extracted from hair at a significantly lower concentration than alternative methods (e.g., urine or oral fluid), rendering hair drug examinations the most challenging methodology to execute.

Confirmation of any positive screening result is performed through techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo a washing procedure before confirmation as needed. The comprehensive laboratory sequence from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair accreditation alongside the ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify substance use for up to 90 days, whereas urine tests have a brief detection period.
• Resistance to deception: It is exceedingly difficult to falsify a hair drug test, enhancing the precision of results.
• Offers historical insight: It can furnish a pattern of substance usage over a duration, not merely recent usage.

Limitations:

• Inability to detect recent consumption: It usually takes 5-7 days for substances to become noticeable in hair.
• Expense: Hair drug assessments are typically pricier compared to other drug test methodologies.
• Result variability: Elements like hair dye and individual differences in hair growth can influence drug metabolite concentration in hair.

Note: Despite often being termed "hair follicle tests", the assessment analyzes the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle drug testing is increasingly preferred over traditional urine tests in Webb, TX. The advantages include superior detection capabilities and reliability. With hair testing, there’s a broader look into drug use history, as it can reveal substance presence long after use.

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.
