Hair Follicle Drug Testing - Ellisville, MO

What it is, How it works

Hair analysis has emerged as an effective method for determining drug and alcohol consumption. Hair retains a lasting record of alcohol and drug use by encapsulating biomarkers in the fibers of the growing hair strand. When cut near the scalp, hair can show evidence of alcohol and other drugs for up to around 3 months. Hair is straightforward to collect, relatively hard to tamper with, and simple to transport.

A 1.5-inch segment of about 200 hair strands (similar in size to a #2 pencil) nearest to the scalp equates to 100mg of hair, which is the preferred sample amount for both screening and confirmation. For EtG, add-ons, or for tests beyond 10 panels, 150mg of hair is suggested. We advise using a jeweler’s scale to measure the specimen. If scalp hair is not available, an equivalent amount of body hair may be taken. When referring to head hair, it specifically means scalp hair. Body hair includes all other types such as facial and axillary hair.

Process Overview

The four primary steps in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the first stage of incorporating a sample into a laboratory's framework. This entails confirming that the sample was properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and concluding any supplementary data entry not provided by an electronic chain of custody system.

Screening may include an initial check for potential drug usage. While Screening is an economical approach for eliminating drug use on the majority of specimens, a positive screen result must be verified to be valid in legal proceedings. Any samples that yield a preliminary positive in Screening necessitate follow-up confirmation.

If a sample shows a preliminary positive during Screening, additional hair is drawn from the original specimen for Extraction. At this phase, drugs are isolated from hair at concentrations much lower than in other test methodologies (e.g., urine or oral fluid), which makes hair drug screening an especially challenging testing method.

Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with leads indicating positivity are cleansed before confirmation if needed. The entire laboratory workflow from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests offer a shorter detection period.
• Hard to manipulate: It is extremely challenging to evade a hair drug test, ensuring more precise results.
• Reveals usage history: It can depict a drug use pattern over time, not limited to recent use.

Limitations:

• Inability to detect recent use: It takes roughly 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests are typically costlier than other drug testing techniques.
• Result variability: Certain factors such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in hair.

Note: While often called "hair follicle tests", this type of test assesses the hair strand, 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.
