Hair Follicle Drug Testing - Gerton, NC

What it is, How it works

Hair testing has become recognized as an effective means for identifying drug and alcohol usage. Hair can reveal an extended history of alcohol and drug intake by embedding biomarkers within the structure of the growing hair shaft. When cut near the scalp, hair can disclose up to a roughly 3-month timeline for alcohol and drug detection. Hair is straightforward to collect, relatively tamper-resistant, and easy to transport.

A sample of 1.5 inches comprising roughly 200 hair strands (equivalent to a #2 pencil's width) taken nearest the scalp will yield 100mg of hair, which is the perfect amount for screening and confirming. For EtG, additional tests, or assessments exceeding 10 panels, 150mg of the sample is advised. It is recommended to weigh the sample using a jeweler’s scale. If scalp hair is absent, a comparable quantity of body hair can be collected. In reference to head hair, we specifically mean scalp hair. Body hair includes all other hair varieties (beard, armpits, etc.).

Process Overview

The four key stages in processing a drug test in the laboratory are Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the preliminary processing of a sample into a lab's system. It involves ensuring the sample was properly sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and concluding any pending data entry not captured by an electronic chain of custody System.

Screening includes a preliminary swift examination for drugs of abuse. While Screening is economically efficient for dismissing drug usage in most samples, a positive screen needs verification to be eligible in court. Any samples with presumptive positivity in Screening require an additional confirmation.

If a sample shows presumptive positivity in the Screening step, more hair is taken from the initial sample and made ready for Extraction. Here, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or saliva), and thus hair drug screening is the toughest method to execute.

Confirmation of any positive Screening outcome is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are washed before confirmation if necessary. The whole lab process from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug tests can recognize drug use for up to 90 days, compared to urine tests that have a briefer detection period.
• Challenging to falsify: Cheating a hair drug test is exceptionally difficult, ensuring more reliable results.
• Supplies historical information: It can present a timeline of drug use over a longer duration, not just recent consumption.

Limitations:

• Cannot identify recent use: It takes roughly 5-7 days for drugs to manifest in hair.
• Expense: Hair drug tests are commonly more costly than other drug testing techniques.
• Result variations: Hair color and personal differences in hair growth can impact the drug metabolite levels in hair.

Note: Despite being commonly called "hair follicle tests", the test evaluates the hair strand and 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.
