Hair Follicle Drug Testing - Doyle, GA

What it is, How it works

Hair testing is widely regarded as an effective method for spotting drug and alcohol consumption. It offers a comprehensive timeline of usage by capturing biomarkers within the hair shaft as it grows. When cut close to the scalp, hair tests can reveal alcohol and drug presence for up to roughly 90 days. Collecting hair is straightforward, presenting challenges to tampering, and is easy to transport.

A sample of 1.5 inches, consisting of roughly 200 hair strands (comparable to the thickness of a #2 pencil), taken nearest to the scalp provides around 100mg of hair, which is the preferred quantity for both screening and verification. For EtG, additional checks, or tests exceeding 10 panels, 150mg of the specimen is advised. We suggest using a jeweler’s scale for weighing the sample. If scalp hair isn’t present, a comparable volume of body hair can be utilized. Head hair specifically refers to scalp strands, while body hair pertains to all other types (such as facial or axillary).

Process Overview

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

Accessioning involves entering the sample into the lab’s system, which includes the verification of proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any additional required data entry not provided by an existing electronic chain of custody system.

Screening serves as a preliminary check for drug abuse. While it's an economical way to dismiss drug use in most cases, a positive result from Screening needs further validation to be court-admissible. Samples indicating presumptive positivity in Screening necessitate further confirmation.

Should a sample appear positive during the Screening phase, additional hair is extracted from the original sample and prepped for Extraction. In this step, drugs are extracted from hair at significantly lower concentrations than other methods (like urine or oral swabs), making hair drug testing one of the more complex methodologies.

Positive screens are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS methods. Samples showing presumptive positivity are cleaned before confirmation if required. The full laboratory protocol from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, a longer period than urine tests.
• Cheating is challenging: It's immensely difficult to falsify a hair drug test, ensuring high result accuracy.
• Gives usage history: It offers insights into drug use patterns over time, in contrast to only recent usage.

Limitations:

• Inability to identify recent use: Drugs become detectable in hair roughly 5-7 days post-consumption.
• Expense: Hair drug testing typically costs more than alternative drug testing methods.
• Result variability: Factors like hair color and individual hair growth differences can impact drug metabolite concentration in hair.

Note: Despite commonly being called "hair follicle tests", the analysis is conducted on the hair strand, 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. 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. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols.
