Hair Follicle Drug Testing - Meeker, LA

What it is, How it works

Hair analysis has increasingly been valued as a robust mechanism for identifying drug and alcohol consumption. Hair offers an extensive timeline of substance usage by embedding biomarkers within the structure of the hair as it grows. When sampled near the scalp, hair can reveal drug and alcohol usage history for nearly three months. Hair collection is straightforward, relatively challenging to tamper with, and convenient to transport.

Acquiring a 1.5-inch segment consisting of about 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal amount for testing and confirmation. For EtG, additional elements, and/or tests exceeding 10 panels, it is advisable to use a 150mg sample. We recommend measuring the sample using a jeweler’s scale. Should scalp hair not be an option, a comparable quantity of body hair can be collected. When mentioning head hair, it specifically refers to hair on the scalp. Body hair encompasses all other types of hair (facial, underarm, etc.).

Process Overview

The laboratory processing of drug test results consists of four principal phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a specimen into a lab's system. This involves verifying that the sample was sealed and sent appropriately, assigning a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry not conducted by an electronic chain of custody system.

Screening refers to an initial brief examination for substances of abuse. While Screening is economical for eliminating drug usage in most samples, any positive screening needs confirmation to be valid in legal proceedings. Presumptive positives in Screening necessitate further confirmation.

If a sample shows presumptive positivity during the Screening phase, additional hair is removed from the original sample and prepared for Extraction. Here, substances are extracted from hair at much lower concentrations compared to other methodologies (e.g., urine or oral fluid), rendering hair drug testing as one of the most challenging methodologies to execute.

Confirmation of any positive outcomes from screening is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positives undergo cleansing before confirmation as needed. The complete laboratory process, spanning from Accessioning to Confirmation, is subjected to scrutiny under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.

Pros of hair drug testing:

• Extended detection window: Hair drug assessments can identify drug use for up to 90 days, as opposed to urine tests which offer a shorter detection framework.
• Hard to falsify: Manipulating a hair drug test is exceedingly challenging, thus enhancing result accuracy.
• Chronological data: It can offer an ongoing record of drug use over time, rather than just recent use.

Drawbacks:

• Incapable of detecting recent consumption: Approximately 5-7 days are required for drugs to appear in hair.
• Cost: Generally, hair drug tests incur higher costs than other drug testing techniques.
• Result variations: Factors like hair color and individual differences in hair growth may impact the concentration of drug metabolites within the hair.

Note: Although frequently known as "hair follicle tests", the assessment actually examines the hair strand and not 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.
