Hair Follicle Drug Testing - Ingram, TX

What it is, How it works

The use of hair testing has been recognized as a potent method for identifying drug and alcohol intake. By embedding biomarkers within the strands of growing hair, hair provides an extended history of substance use. When hair is harvested near the scalp, it can offer a detection period of up to about three months for substances like alcohol and drugs. The process for collecting hair is straightforward, somewhat resistant to tampering, and convenient for shipping.

A sample measuring 1.5 inches with roughly 200 hair strands (equivalent to the thickness of a #2 pencil) taken nearest to the scalp yields 100mg of hair, which is the desired amount for both screening and confirmation. For EtG, additional testing, and/or analysis beyond ten panels, a 150mg sample is suggested. It's advised to measure the sample using a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair may be gathered. The term "head hair" pertains solely to scalp hair, whereas "body hair" encompasses all other types of hair (such as facial or axillary).

Process Overview

The main stages involved in laboratory analysis of drug test results are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample enters the laboratory’s system. This process verifies proper sealing and shipment of the sample, assigns a unique LAN (Laboratory Accessioning Number), and completes any additional data input that the electronic chain of custody system might not cover.

Screening is a preliminary rapid assessment for drugs of abuse. Though Screening is cost-effective in excluding drug usage for most samples, a positive result must be confirmed to be valid in legal contexts. Any samples that produce a presumptive positive in Screening must undergo secondary confirmation.

Should a sample yield a presumptive positive during Screening, additional hair is extracted from the original sample to prepare for Extraction. This step involves withdrawing drugs from hair at significantly lower concentrations compared to other methods like urine or oral fluid, making hair drug screening a challenging technique to execute.

Confirmation for any positive result from screening is carried out with GC/MS, GC/MS/MS, or LC/MS/MS. All samples that yield a presumptive positive are cleansed before confirmation if necessary. The entire process from Accessioning to Confirmation is subject to scrutiny under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug use up to 90 days, unlike urine tests which have a briefer detection period.
• Hard to circumvent: Cheating a hair drug test is extremely challenging, resulting in more credible results.
• Provides historical usage data: It can illustrate a timeline of drug use over an extended period, rather than just recent use.

Limitations:

• Unable to detect recent use: Drugs become detectable in hair approximately 5-7 days after usage.
• Expense: Hair drug tests usually incur higher costs than other testing methods.
• Result variation: Factors like hair color and individual hair growth differences can alter the concentration of drug residues in hair.

Note: Despite being commonly called "hair follicle tests", the procedure evaluates the hair strand rather than the hair follicle beneath the scalp.

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.
