Hair Follicle Drug Testing - Leola, AR

What it is, How it works

Hair testing is recognized as a compelling method for uncovering the consumption of alcohol and drugs. Hair offers a protracted record of alcohol and other substances by embedding biomarkers in the fibers of the developing hair strand. When taken near the scalp, hair can present up to a roughly 90-day detection window for substances. Hair is straightforward to gather, somewhat challenging to falsify, and uncomplicated to send.

A 1.5-inch portion consisting of around 200 hair strands (similar in size to a #2 pencil) close to the scalp will supply 100mg of hair, which is the optimal sample for assessment and verification. When testing for EtG, additional substances, or conducting analyses above 10 panels, 150mg of the sample is advised. It is recommended to measure the sample using a jeweler's scale. If scalp hair is not present, an equivalent quantity of body hair may be gathered. In the context of head hair, we only denote scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves incorporating a sample into a laboratory’s system at the onset. This entails confirming the sample was sealed and shipped correctly, assigning a unique LAN (Laboratory Accessioning Number), and concluding any supplementary data input absent from an electronic chain of custody system.

Screening constitutes an initial rapid assessment for substances of abuse. While Screening offers a cost-effective means to negate drug usage for most samples, a positive outcome requires confirmation to be court admissible. Any samples tentatively positive in Screening necessitate a subsequent verification.

Should a sample show as tentatively positive in the Screening stage, additional hair is extracted from the primary sample and readied for Extraction. At this stage, substances are isolated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging technique to apply.

Verification of any positive screening result is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumptively positive undergo washing prior to verification as necessary. The entire laboratory sequence from Accessioning to Verification is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests are capable of identifying drug usage for up to 90 days, unlike urine tests which have a shorter detection period.
• Hard to manipulate: Cheating a hair drug test is quite tough, thus heightening the accuracy of results.
• Offers historical insights: It can reveal a trend of drug usage over some time, not just recent consumption.

Limitations:

• Inability to identify recent use: Drugs become traceable in hair after around 5-7 days.
• Expense: Hair drug tests are typically more costly than other drug testing techniques.
• Result variability: Elements such as hair color and individual discrepancies in hair growth can affect the concentration of drug metabolites in the hair.

Note: Often termed as "hair follicle tests", the analysis targets the hair strand rather than the hair follicle located 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.
