Hair Follicle Drug Testing - Vermontville, MI

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of drug and alcohol use by embedding biomarkers within the strands as they grow. When collected close to the scalp, hair can offer a detection window of up to three months for drugs and alcohol. The collection process is straightforward, making it hard to tamper with, and easy to transport.

A 1.5-inch sample containing roughly 200 strands of hair (comparable to a #2 pencil size) nearest to the scalp will yield 100mg of hair, which is the optimal sample size for screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, 150mg of the sample is preferable. We advise weighing the sample using a jeweler’s scale. In the case that scalp hair is missing, an equivalent amount of body hair can be gathered. Head hair explicitly refers to scalp hair, while body hair pertains to other types (such as facial or axillary hair).

Process Overview

There are four fundamental stages in the laboratory processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary processing of a sample into a laboratory’s database. This process includes confirming the sample's proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and entering any supplementary data not recorded by an electronic chain of custody system.

Screening is a preliminary check for drugs of abuse. Although Screening is a cost-efficient method to rule out drug use in most samples, a positive screen must be confirmed to be legally admissible in court. Any samples that are preliminary positive in Screening necessitate a secondary confirmation.

If a sample is preliminarily positive at the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. During this stage, the drugs are retrieved from hair at a significantly lower concentration than with other methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methodologies to execute.

All positive screening results are verified using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are cleaned 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 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can detect drug usage for up to 90 days, unlike urine tests which have a more limited detection window.
• Hard to manipulate: Cheating on a hair drug test is very difficult, enhancing the accuracy of the results.
• Provides usage trends: It can illustrate a pattern of drug use over time, rather than just indicating recent use.

Limitations:

• Cannot identify recent usage: Drugs take about 5-7 days to become detectable in hair.
• Expense: Hair drug tests generally cost more than other drug testing methods.
• Result variability: Factors such as hair color and individual hair growth variations can influence the concentration of drug metabolites in the hair.

Note: Although often called "hair follicle tests", the test itself examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why do hair follicle tests excel over traditional urine tests in Vermontville, MI? The benefits are clear: hair testing offers an extended detection window, capturing a longer history of substance use.

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.
