Hair Follicle Drug Testing - Nokesville, VA

What it is, How it works

Hair screening is now recognized as a notable method for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and drug use by embedding biomarkers within the fibers of the developing hair strand. When extracted near the scalp, hair can reveal approximately a 3-month time frame for alcohol and drug detection. The collection of hair is uncomplicated, relatively tamper-proof, and convenient for shipping.

A hair sample of 1.5 inches, comprising around 200 strands (about the size of a #2 pencil) nearest to the scalp, provides 100mg of hair, which is the perfect amount for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a 150mg specimen is suggested. It's recommended to measure the specimen using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be gathered. When discussing head hair, it specifically refers to scalp hair. Body hair encompasses all other types of hair (such as facial or axillary hair).

Process Overview

There are four primary steps in the laboratory process for producing a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the preliminary integration of a sample into the laboratory system. It involves ensuring that the sample was accurately sealed and mailed, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry absent from an electronic chain of custody system.

Screening serves as a preliminary efficient check for substance abuse. Although Screening is a cost-effective method to dismiss drug usage for most samples, any positive screen must be verified to be court-admissible. Samples showing presumptive positivity in Screening necessitate further confirmation.

In the event of a presumptive positive result during Screening, additional hair is extracted from the initial sample for preparation in the Extraction phase. During this phase, substances are isolated from the hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which makes hair drug screening one of the most challenging methodologies to execute.

Confirmation for any positive screening finding is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are cleansed before confirmation as required. The overall laboratory procedure, 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:

• Extended detection period: Hair drug assessments can identify drug use for up to 90 days, unlike urine tests which offer a shorter detection period.
• Challenging to falsify: Cheating a hair drug test is notably difficult, hence the results are more reliable.
• Reveals usage history: It can reflect a trend of drug consumption over an extended period, not just recent usage.

Limitations:

• Incapable of detecting recent usage: Drugs take roughly 5-7 days to become detectable in hair.
• Expense: Hair drug testing usually involves higher costs compared to other drug testing methods.
• Result variations: Aspects like hair color and individual hair growth differences can influence the concentration of drug metabolites in the hair.

Note: The term "hair follicle tests" often used refers to the analysis of the hair strand, not the hair 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.
