Hair Follicle Drug Testing - Mount Calm, TX

What it is, How it works

Over time, hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair captures a detailed record of alcohol and drug use due to biomarkers being embedded within the hair strands. When hair is taken near the scalp, it can reflect drug and alcohol exposure over a period of up to three months. The process of collecting hair is straightforward, challenging to tamper with, and convenient to transport.

To obtain an optimal sample for analysis, a 1.5-inch segment of roughly 200 hair strands (approximately equivalent to the thickness of a #2 pencil) from the scalp, which weighs around 100mg, is ideal. For specific tests like EtG or those surpassing ten panels, 150mg is advised. We suggest using a jeweler’s scale for precise measurement. Should scalp hair be nonexistent, the collection of a comparable amount of body hair is acceptable. "Head hair" specifically refers to scalp hair, while "body hair" includes all other types (such as facial or axillary hair).

Process Overview

The laboratory procedure for processing a drug test result consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step where a sample is introduced into the lab's system. This step involves confirming that the sample is properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data entry not available through an electronic chain of custody.

Screening provides an initial evaluation for drug presence. This cost-efficient approach can identify potential drug use in most samples; however, any positive findings require confirmation to be legally acceptable. Samples appearing positive in Screening necessitate further verification through secondary procedures.

Should Screening suggest positivity, additional hair is extracted from the original specimen for further processing in the Extraction stage. Here, drugs are isolated from hair at concentrations lower than other methods like urine or oral fluid, marking hair testing as a complex technique.

Confirmation of positive screenings is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Positively flagged samples undergo necessary washing before confirmation. The entire procedure, from Accessioning to Confirmation, adheres to CAP (College of American Pathologists) Hair guidelines and complies with ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can reveal drug use for up to 90 days, whereas urine tests offer a shorter detection timeframe.
• High accuracy: Due to its challenging nature to manipulate, hair testing results are considered highly reliable.
• Historical insight: It unveils a chronology of drug use, not just recent activity.

Limitations:

• Delayed detection: There’s a 5-7 day lag before drugs are traceable in hair.
• Expense: Typically, hair tests incur higher costs than alternative drug testing methods.
• Result variability: Elements like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: While occasionally termed as "hair follicle tests," the analysis focuses on the hair strand itself, excluding the 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.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
