Hair Follicle Drug Testing - Monroe, LA

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol use. Hair offers a prolonged history of alcohol and drug consumption by encapsulating biomarkers within the strands of growing hair. When obtained near the scalp, hair can provide an approximate 3-month detection period for alcohol and drugs. Hair is easy to gather, challenging to tamper with, and simple to transport.

A 1.5-inch portion of about 200 hair strands (about the thickness of a #2 pencil) from near the scalp supplies 100mg of hair, which is ideal for screening and confirmation. For EtG, additional testing or tests beyond 10 panels, it is advised to use 150mg of the specimen. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair is unavailable, an equivalent amount of body hair can be collected. The term head hair specifically refers to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The four crucial stages in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves integrating the sample into the laboratory’s system. It includes confirming that the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.

Screening is a preliminary quick assessment for drugs of abuse. Although Screening is an economical method to rule out drug usage in most samples, a positive screen must be confirmed to be court-admissible. Any samples that are presumptively positive during Screening need a secondary confirmation.

If a sample is presumptively positive at the Screening stage, additional hair is extracted from the initial specimen for Extraction. At this stage, drugs are extracted from hair at considerably lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to conduct.

The confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned before confirmation if necessary. The entire lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can uncover drug use for up to 90 days, unlike urine tests which have a short detection window.
• Difficulty to cheat: Hair drug tests are hard to deceive, thus producing more accurate results.
• Provides historical data: It reveals a pattern of drug use over time rather than just recent use.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair roughly 5-7 days after use.
• Cost: Hair drug tests typically cost more compared to other drug testing methods.
• Variations in results: Elements like hair color and individual differences in hair growth can impact drug metabolite concentration in hair.

Note: Often known as "hair follicle tests", the analysis targets the hair strand, not the follicle below 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.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings.
