Hair Follicle Drug Testing - Loganville, PA

What it is, How it works

Hair analysis has emerged as a potent method for detecting drug and alcohol consumption. Hair fibers capture biomarkers over time, providing a comprehensive substance history. Sampling hair close to the scalp allows approximately a 3-month detection timeframe for alcohol and drugs. It is easy to collect, hard to tamper with, and simple to transport.

Collecting a 1.5-inch piece comprising about 200 hairs (roughly the thickness of a #2 pencil) nearest the scalp yields 100mg, which is perfect for both screening and confirmation. For additional testing like EtG, extras, or tests surpassing 10 panels, 150mg is advised. We suggest using a jeweler's scale for specimen measurement. When scalp hair is unavailable, equivalent body hair can be used. “Head hair” pertains to scalp hair exclusively, while “body hair” encompasses all other types (such as facial, axillary, etc.).

Process Overview

Drug test result processing in a lab follows four major steps: Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, the sample undergoes initial processing within the lab's system. This involves ensuring the sample was sealed and sent correctly, assigning it a unique LAN (Laboratory Accessioning Number), and completing any supplementary data not recorded by an electronic chain of custody system.

Screening serves as a preliminary check for substance abuse. Though it economically excludes drug usage in most samples, a positive screen must be validated to be accepted in legal contexts. Samples testing positive in Screening necessitate further confirmation.

Samples flagged as presumptively positive in Screening undergo further Extraction by retrieving more hair from the initial sample. Here, drugs are isolated from hair at lower concentrations than other methods (e.g., urine or oral fluid), rendering hair drug screening more challenging.

Positive screening results are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Prior to confirmation, all presumptive positive samples are washed as required. The comprehensive lab process from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests with a shorter detection range.
• Resistance to tampering: Manipulating a hair drug test is quite challenging, ensuring accurate outcomes.
• Historical insights: Provides a pattern of drug use over time, beyond just recent consumption.

Limitations:

• Inability to detect recent usage: It takes roughly 5-7 days before drugs are traceable in hair.
• Expense: Generally pricier than other drug testing options.
• Result variability: Elements such as hair color and individual growth differences can influence metabolite concentrations in hair.

Note: Although often termed “hair follicle tests,” the analysis targets the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Loganville, PA, the choice for drug testing is shifting towards hair analysis due to its undeniable benefits over urine screening. Hair testing enhances detection accuracy and reliability.

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.
