Hair Follicle Drug Testing - Point Blank, TX

What it is, How it works

Hair testing is now recognized as an effective means for detecting drug and alcohol usage. Hair captures a long-term record of alcohol and drug intake by embedding biomarkers in the fibers of the hair strand as it grows. When sourced near the scalp, hair offers around a 3-month detection period for alcohol and substances. Hair samples are easy to obtain, relatively hard to tamper with, and simple to transport.

A sample measuring 1.5 inches, consisting of roughly 200 hair strands (comparable to the girth of a #2 pencil) nearest the scalp, yields 100mg of hair, the optimal amount for both screening and confirmation stages. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg sample is advisable. It is suggested to weigh the sample using a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair can be used. By “head hair”, we specifically mean scalp hair. “Body hair” encompasses all other hair categories (such as facial or axillary hair).

Process Overview

The lab processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the initial handling of a sample when it enters a laboratory’s system. This step includes ensuring the sample's seal and proper shipment, assigning a random LAN (Laboratory Accessioning Number), and addressing any necessary data entry not covered by an electronic chain of custody system.

Screening offers a preliminary check for potential drug abuse. It's a cost-effective means to dismiss drug use in most samples; however, a positive screen necessitates confirmation to be valid in legal settings. Any samples yielding presumptive positives in Screening require confirmation in secondary testing.

Should a sample display presumptive positivity in Screening, additional hair is extracted from the original specimen for the Extraction phase. Here, drugs are separated from hair at a significantly lower concentration than in other testing methods (such as urine or oral fluid), explaining why hair drug screening ranks as the most challenging method to execute.

The Confirmation of any positive Screening results is performed with GC/MS, GC/MS/MS, or LC/MS/MS techniques. Every presumptive positive sample undergoes washing before Confirmation as required. The full laboratory procedure, from Accessioning to Confirmation, is evaluated under the guidelines of both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage over a span of up to 90 days, unlike urine tests which offer a shorter window of detection.
• Hard to manipulate: Cheating a hair drug test is exceedingly difficult, enhancing the reliability of results.
• Chronological data: These tests can indicate drug use patterns over time, rather than just recent consumption.

Limitations:

• Cannot identify recent usage: Drugs become detectable in hair roughly 5-7 days post-use.
• Expense: Hair drug tests generally come at a higher cost compared to other testing techniques.
• Result variability: Aspects like hair color and individual hair growth rates can influence drug metabolite concentrations in hair.

Note: Although often termed "hair follicle tests", the analysis actually examines the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing the benefits of hair testing to urine testing in Point Blank, TX, hair follicle tests emerge as the superior choice. The reliability and accuracy of hair testing surpass traditional methods. Employers seeking longer detection periods turn to hair testing to ensure better accuracy.

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.
