Hair Follicle Drug Testing - Glen Aubrey, NY

What it is, How it works

Hair analysis has emerged as an effective instrument in identifying drug and alcohol consumption. The strands capture a historical timeline of substance use by embedding biomarkers within their structure. When collected in close proximity to the scalp, hair offers almost a 3-month span for alcohol and drug detection. Hair samples are straightforward to gather, challenging to tamper with, and convenient to transport.

A 1.5-inch hair section, comprising roughly 200 strands (similar in size to a #2 pencil) near the scalp, yields 100mg of hair, an optimal sample size for both screening and verification. For EtG evaluations, extended panels, and tests exceeding 10 panels, 150mg of the specimen is suggested. It is advisable to measure the sample with a jeweler's scale. If scalp hair is not available, an equivalent amount of body hair is collectable. Head hair specifically refers to scalp strands, while body hair denotes all other types (such as facial, axillary, etc.).

Process Overview

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

Accessioning comprises the initial integration of a sample into a lab's protocol. This step includes ensuring the sample was sealed and delivered correctly, generating a random LAN (Laboratory Accessioning Number), and completing additional data input absent from an electronic chain of custody system.

Screening offers an expedited assessment for controlled substances. While cost-efficient, any positive results require confirmation to hold up in legal settings. Samples testing positive during Screening necessitate further verification.

Following a positive result in Screening, additional hair is extracted from the initial sample and readied for Extraction. Here, drugs are isolated from hair at a considerably lower concentration compared to other methods (e.g., urine or oral fluid), rendering hair drug screening particularly challenging.

Confirmation of any affirmative screening outcomes is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples deemed presumptive positive undergo washing before confirmation as necessary. The entire laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair guidelines and adherence to ISO / IEC 17025 benchmarks.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug assays can reveal drug use up to 90 days prior, unlike urine examinations that offer a limited window.
• Low susceptibility to tampering: Hair drug tests are notably resistant to manipulation, enhancing result reliability.
• Chronological insight: It charts drug use patterns over time, rather than just recent intake.

Limitations:

• Inability to detect recent usage: Drugs become traceable in hair roughly 5-7 days post-consumption.
• Expense: Hair drug assays tend to be pricier compared to alternative testing techniques.
• Result variability: Factors like hair color and individual growth differences can impact drug metabolite levels in hair.

Note: Although often termed "hair follicle tests", the assessment actually examines the hair shaft, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Glen Aubrey, NY centers around its superior detection capabilities. Unlike traditional urine tests, hair follicle assessments provide more reliable and comprehensive substance detection, capturing a longer history of drug use with accuracy and robustness that urine tests cannot match.

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.
