Hair Follicle Drug Testing - Dante, VA

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a comprehensive record of substance use by embedding biomarkers within the strands of the hair as it grows. When taken near the scalp, hair can provide an approximate three-month detection period for alcohol and drugs. The collection of hair is straightforward, relatively resistant to tampering, and easy to transport.

A 1.5-inch segment comprising around 200 hair strands (equivalent to a #2 pencil's thickness) closest to the scalp yields 100mg of hair, which is the ideal amount for screening and confirmation. For EtG, additional tests, and examinations above 10 panels, a sample weighing 150mg is suggested. To ensure precision, we suggest using a jeweler's scale for weighing. In cases where scalp hair is absent, a similar quantity of body hair can be used. Head hair refers specifically to scalp hair. Body hair pertains to all other types such as facial, underarm, etc.

Process Overview

The drug testing process in the lab is composed of four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial handling of a specimen within the laboratory's system. This step includes confirming that the sample is sealed and shipped securely, allocating a random LAN (Laboratory Accessioning Number), and completing any additional data entry not automated by the electronic chain of custody system.

Screening consists of an initial, rapid assessment for drug use. While Screening is a cost-saving method to eliminate drug use from most samples, a positive screen requires confirmation to be court-admissible. Samples that are presumptively positive in Screening necessitate further confirmation.

If a specimen is presumptively positive during the Screening phase, additional hair is taken from the original sample and prepared for Extraction. In this step, substances are extracted from hair at a lower concentration than with other methods (such as urine or oral fluid), marking hair drug screening as the most challenging method to execute.

Confirmation for any positive screening results is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples considered presumptively positive are cleansed before confirmation as needed. The entire sequence from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can uncover drug use up to 90 days back, unlike urine tests which offer a shorter detection scope.
• Hard to manipulate: Cheating a hair drug test is extremely difficult, which enhances result accuracy.
• Delivers long-term patterns: It offers insights into drug use trends over time rather than just recent intake.

Limitations:

• Cannot detect recent intake: Drugs become detectable in hair about 5-7 days post-consumption.
• Expense: Hair drug tests generally cost more than other testing methods.
• Result variations: Elements like hair color and individual differences in hair growth can impact drug metabolite concentrations in the hair.

Note: While commonly termed as "hair follicle tests", the analysis itself is performed on the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
