Hair Follicle Drug Testing - Proctor, MN

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. Hair offers a prolonged record of alcohol and drug presence due to biomarkers being embedded in the developing strand fibers. When gathered near the scalp, it can reveal a substance usage history of approximately three months. Hair is straightforward to collect, challenging to tamper with, and convenient to transport.

A 1.5-inch segment with roughly 200 hair strands (comparable to a #2 pencil) closest to the scalp offers 100mg of hair, which is the preferred amount for screening and confirmation. For EtG add-ons or for tests exceeding 10 panels, 150mg is advisable. It's suggested to measure the specimen on a jeweler’s scale. If head hair isn't accessible, an equal quantity of body hair can be used. When mentioning head hair, it refers solely to scalp hair. Body hair signifies any other hair categories (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four crucial steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage where a sample is incorporated into a lab’s system. This step ensures the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and includes any additional data entry absent from an electronic chain of custody system.

Screening includes a preliminary rapid assessment for drug abuse. Though Screening is a cost-efficient way to eliminate drug usage on most samples, a positive screen requires confirmation to be valid in legal contexts. Any samples testing as presumptively positive during Screening necessitate a secondary confirmation.

If a sample is categorized as presumptively positive at the Screening phase, further hair is extracted from the initial sample and readied for Extraction. During this phase, drugs are extracted from the hair at a significantly lower concentration than other methodologies (e.g., urine or oral fluid), highlighting why hair drug testing is the most challenging methodology to administer.

Confirmation for any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug tests identify drug consumption up to 90 days, unlike urine tests which have a shorter detection span.
• Difficult to deceive: Cheating a hair drug test is very challenging, ensuring more accurate results.
• Provides historical insights: It delivers a pattern of drug use spanning a duration, not merely recent consumption.

Limitations:

• Unable to detect recent use: Drugs take about 5-7 days to become traceable in hair.
• Expense: Hair drug tests are typically more costly compared to other drug testing techniques.
• Result variability: Elements like hair color and personal differences in hair growth can impact drug metabolite concentrations within the hair.

Note: While often termed as "hair follicle tests," the evaluation 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. 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.
