Hair Follicle Drug Testing - Dunwoody, GA

What it is, How it works

Hair testing is recognized as an effective method for identifying the usage of drugs and alcohol. Hair strands retain a long-term history of alcohol and other drug consumption by embedding biomarkers within the fibers of the hair as it grows. When gathered near the scalp, hair can offer a detection period of up to roughly three months for alcohol and drugs. Hair is easy to collect, relatively hard to tamper with, and straightforward to transport.

A sample of 1.5 inches comprising around 200 strands closest to the scalp will yield 100mg of hair, considered the optimal sample for screening as well as confirmation. For EtG and additional panels above 10, a specimen of 150mg is advisable. It’s recommended to weigh the sample using a jeweler's scale. If scalp hair isn’t available, a similar amount of body hair can be gathered. By head hair, we mean specifically scalp hair. Body hair includes all other types (such as facial or axillary hair).

Process Overview

The primary stages encompassed in the laboratory analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, initial processing incorporates the sample into the laboratory’s system. This step consists of ensuring the sample was appropriately sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry not captured by an electronic chain of custody framework.

Screening serves as an initial rapid assessment for substances of abuse. Although Screening is a budget-friendly strategy to discount drug use in many samples, any positive screen results require confirmation for judicial admissibility. Any samples with a presumptive positive result during Screening necessitate secondary verification.

For any presumptively positive sample at the Screening stage, additional hair is drawn from the initial specimen and set up for Extraction. In this stage, drugs are extracted from hair at significantly lower concentrations than alternative methodologies (like urine or oral fluid), making hair drug screening the most challenging methodology to execute.

Confirmation of any negative screening result is performed using GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo a washing process before confirmation as deemed necessary. The entirety of the laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug evaluations can uncover drug use extending up to 90 days, whereas urine tests cover a shorter detection span.
• Challenging to manipulate: Cheating a hair drug examination is extremely difficult, enhancing the reliability of the results.
• Historic data provision: It highlights a drug usage pattern over time, beyond recent consumption.

Limitations:

• Incapable of detecting recent usage: It takes around 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug evaluations tend to be pricier compared to other drug testing approaches.
• Result variations: Elements such as hair color and unique hair growth variations can influence the concentration of drug metabolites in hair.

Note: Often labeled as "hair follicle tests", the examination actually evaluates the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Dunwoody, GA, surpasses urine testing by providing superior detection accuracy. Unlike urine tests which have a limited short-term detection window, hair testing examines a broader timeline, usually up to 90 days.

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.
