Hair Follicle Drug Testing - Knob Creek, TN

What it is, How it works

Hair analysis has grown to be recognized as an effective method for identifying drug and alcohol consumption. Hair captures a record of alcohol and drug intake over time by holding biomarkers within the hair strand as it grows. Collected near the scalp, it allows for up to a three-month window of detection for alcohol and drugs. Hair is easy to gather, somewhat challenging to tamper with, and simple to transport.

A section of hair measuring 1.5 inches with about 200 strands (equivalent to a #2 pencil) near the scalp offers 100mg of hair, ideal for both screening and confirming results. For EtG, additional panels, or tests exceeding 10 panels, a collection of 150mg is advised. Using a jeweler’s scale to weigh the sample is recommended. If scalp hair is unavailable, equivalent body hair may be used. In reference to head hair, we mean only scalp hair. Body hair includes all other types such as facial and axillary hair.

Process Overview

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

Accessioning involves entering a sample into a lab’s system. This step includes ensuring the sample was properly sealed and sent, assigning a Laboratory Accessioning Number (LAN), and completing any missing data entry not covered by electronic chain of custody systems.

Screening entails a quick initial check for drugs of abuse. Although it’s a cost-effective way to eliminate the possibility of drug use in most samples, a positive screen must be confirmed for court acceptance. Samples showing presumptive positive results in Screening require additional confirmation.

If presumptively positive in the Screening stage, the sample undergoes additional hair collection for Extraction. This step extracts drugs from hair at a lower concentration compared to other methods like urine or oral fluid, enhancing the complexity of hair drug screening.

Confirmation of positive screening results employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. Samples showing presumptive positives are washed before confirmation as needed. The complete process from Accessioning to Confirmation is verified under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection: Hair drug tests can identify drug use over a 90-day period, while urine tests have a shorter detection range.
• Hard to falsify: Manipulating a hair drug test is very challenging, thus ensuring more accurate outcomes.
• Shows drug usage history: Provides an overview of drug usage over time, not just recent use.

Limitations:

• Not effective for recent use: There is a delay of 5-7 days before drugs become detectable in hair.
• Expense: Hair drug tests typically cost more than other testing methods.
• Result variation: Individual differences such as hair color and growth rates can influence drug metabolite levels in hair.

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

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle tests to urine analyses, the former triumphs in Knob Creek, TN with its unmatched detection accuracy and reliability.

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.
