Hair Follicle Drug Testing - Northfield, NJ

What it is, How it works

Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair retains a long-lasting record of alcohol and other substances by embedding biomarkers within the strands of the developing hair. By collecting hair near the scalp, it offers up to a three-month detection period for alcohol and various drugs. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.

A 1.5-inch segment of about 200 hair strands (roughly the size of a #2 pencil) taken nearest to the scalp provides 100mg of hair, the optimal amount for screening and validation. For EtG, additional tests, and panels beyond ten, 150mg is suggested. Utilizing a jeweler’s scale is suggested for weighing the specimen. If scalp hair cannot be obtained, a comparable quantity of body hair may be used. 'Head hair' specifically refers to scalp hair, while 'body hair' covers all other types (facial, axillary, etc.).

Process Overview

The laboratory evaluation of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning deals with the preliminary handling of a specimen in a lab's system, ensuring the sample was properly sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and filling in any missing data not captured by an electronic chain of custody system.

Screening performs an initial quick test for drugs of abuse. Although it provides an economical method to eliminate drug use in most samples, a positive screen must be affirmed to be permissible in court, requiring secondary confirmation for presumptively positive samples.

In the Screening phase, if a sample appears positive, additional hair is extracted from the initial amount for Extraction. At this point, drugs are removed from the hair at significantly lower concentrations than other techniques (such as urine or oral fluid), making hair drug screening a challenging procedure.

Confirmation of any positive screening outcome is completed through GC/MS, GC/MS/MS, or LC/MS/MS. Every sample showing presumptive positive results is washed as necessary prior to confirmation. The entire laboratory workflow from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, whereas urine tests offer a much shorter detection timeframe.
• High resistance to tampering: Hair drug tests are hard to manipulate, thus delivering more reliable results.
• Historic data provision: These tests reveal drug use patterns over time, rather than just recent consumption.

Limitations:

• Inability to detect recent use: Drugs typically take about 5-7 days to become noticeable in hair.
• Expense: Hair drug tests are usually costlier than other testing approaches.
• Result variations: Factors like hair color and personal hair growth rates can influence drug metabolite concentrations in hair.

Note: Although frequently called "hair follicle tests," the test actually examines 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.
