Hair Follicle Drug Testing - Bellerive Acres, MO

What it is, How it works

Hair analysis is recognized as a compelling approach for identifying drug and alcohol consumption. Hair captures a long-lasting record of alcohol and drug intake by embedding biomarkers in the strands as they develop. When taken close to the scalp, hair can present roughly a three-month detection timeframe for alcohol and drug presence. Collecting hair is straightforward, relatively hard to tamper with, and convenient to transport.

An ideal sample size for testing and confirmation is a 1.5-inch length comprising about 200 strands of hair (about the size of a #2 pencil) from nearest the scalp, offering 100mg of hair. For EtG, supplementary tests, and/or tests more than 10 panels, 150mg of the sample is suggested. It is advisable to weigh the sample with a jeweler’s scale. Should scalp hair be inaccessible, a similar quantity of body hair can be gathered. When mentioning head hair, we exclusively refer to scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

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

In Accessioning, the sample enters the laboratory's system for initial processing. This step includes ensuring the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not available through an electronic chain of custody system.

Screening involves a swift preliminary check for substances of abuse. Although Screening is efficient for ruling out drug usage in most samples, any positive Screening needs confirmation for legal admissibility. Presumptively positive samples in Screening necessitate further confirmation.

Upon a presumptive positive result in the Screening phase, additional hair is taken from the initial sample for Extraction. At this point, drugs are extracted from hair at much lower concentrations than with other methods (such as urine or oral fluid), contributing to the complexity of hair drug screening.

GC/MS, GC/MS/MS, or LC/MS/MS are used to confirm any positive Screening outcomes. Pre-confirmation washing is performed on all presumptive positive samples as needed. The complete laboratory process—from Accessioning to Confirmation—is scrutinized according to both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests which offer a shorter detection period.
• Hard to fake: Cheating on a hair drug test is quite challenging, enhancing result accuracy.
• Offers historical insights: It provides a user’s drug use pattern over time, beyond recent usage.

Limitations:

• Incapable of detecting recent use: It usually takes 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug testing generally costs more than other drug-testing methods.
• Result variations: Elements like hair color and individual growth rates can influence drug metabolite concentration in hair.

Note: Commonly known as "hair follicle tests", the test focuses on the hair strand instead of 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.
