Hair Follicle Drug Testing - Pontiac, MI

What it is, How it works

Hair examining has emerged as a significant method for detecting drug and alcohol consumption. Hair captures a prolonged history of alcohol and drug use by embedding biomarkers within the growing hair strand. By collecting hair close to the scalp, it offers a detection period of up to roughly 90 days for substances. It is straightforward to collect, challenging to tamper with, and convenient to send.

A 1.5-inch collection of around 200 hair strands (roughly the dimension of a #2 pencil) near the scalp yields 100mg of hair, the ideal amount for analysis and verification. For EtG, additional tests, or evaluations exceeding 10 panels, 150mg of hair is advised. We suggest measuring the hair sample with a jeweler’s scale. If scalp hair is missing, a similar amount of body hair can be utilized. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other forms of hair (facial, axillary, etc.).

Process Overview

The four main phases in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the initial integration of a sample into a lab's system. This involves confirming the sample was sealed and transported correctly, assigning it a random LAN (Laboratory Accessioning Number), and completing any other data input not provided by an electronic custody chain.

Screening provides a preliminary assessment for drug abuse. While it serves as a financially logical way to exclude drug presence in most samples, any positive findings require confirmation for court admissibility. Samples that show a presumptive positive in Screening necessitate additional verification.

If Screening uncovers a presumptive positive, additional hair is extracted from the initial sample for Extraction. Here, drugs are isolated from hair at concentrations lower than other methodologies (e.g., urine or oral fluid), making hair drug analysis the most challenging method to perform.

Confirmation of positive findings from Screening is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation if necessary. The entire laboratory procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection timeline: Hair drug assessments can discover drug consumption for up to 90 days, in contrast to urine tests with shorter timelines.
• Hard to falsify: Successfully cheating a hair drug test is very challenging, providing more reliable results.
• Offers historical insights: It can indicate a timeline of drug use over time, rather than just recent occurrences.

Limitations:

• Inability to detect recent usage: It approximately takes 5-7 days for drugs to appear in hair.
• Expense: Hair drug evaluations are typically costlier than other drug testing ways.
• Result variability: Elements such as hair color and individual hair growth variations can influence drug metabolite concentration in hair.

Note: Although often termed as "hair follicle tests," the evaluation focuses on analyzing the hair strand, not the scalp follicle.

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.
