Hair Follicle Drug Testing - Coburn, PA

What it is, How it works

Hair analysis has emerged as an effective means for identifying substance and alcohol consumption. Hair retains a comprehensive record of alcohol and drug exposure by embedding biomarkers within the strands as they grow. If collected close to the head, hair offers an approximate 90-day window for detecting drug and alcohol presence. Gathering hair is straightforward, somewhat resistant to tampering, and simple to transport.

A section measuring 1.5 inches with approximately 200 hair strands (roughly the thickness of a #2 pencil) retrieved nearest to the scalp can yield 100mg of hair, the optimal amount needed for testing and validation. For testing that includes EtG, additional compounds, or exceeds a 10-panel screen, 150mg is advised. It is suggested that the hair sample's weight be verified using a jeweler's scale. In cases where scalp hair is inaccessible, an equivalent volume of body hair can be collected. When we speak of head hair, we mean scalp hair exclusively. Body hair encompasses any other types (such as facial, underarm, etc.).

Process Overview

The laboratory examination of a drug test consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of incorporating a specimen into the lab's framework. This ensures the specimen was correctly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and completes any missing data entry from an electronic tracking system.

Screening serves as a preliminary, cost-efficient assessment for banned substances. Although Screening effectively excludes drug presence for most specimens, a positive result necessitates confirmation to be legally acceptable. All samples indicating a likely positive outcome in Screening must undergo further verification.

Should a sample indicate a likely positive during Screening, additional hair is extracted from the original sample and set up for Extraction. In this phase, drugs are withdrawn from hair at concentrations much lower than other methods (e.g., urine or saliva), making hair testing the most challenging to execute.

A confirmed positive result from Screening proceeds to further validation through GC/MS, GC/MS/MS, or LC/MS/MS. Each presumed positive sample is cleaned before confirmation as required. The entire laboratory process from Accessioning to Confirmation undergoes evaluation under both the CAP (College of American Pathologists) Hair guidance and adherence to ISO / IEC 17025 criteria.

Advantages of hair drug testing:

• Extended detection period: Hair drug analyses can reveal drug intake for up to 90 days, as opposed to urine analyses with shorter detection timelines.
• Challenging to manipulate: Cheating a hair drug test is exceedingly difficult, thus enhancing result accuracy.
• Displays historical usage: It can illustrate a pattern of substance intake over time, not just recent activity.

Limitations:

• Incapable of detecting recent use: It generally takes 5-7 days for drugs to surface in hair.
• Expense: Hair analyses are typically pricier than other testing approaches.
• Result variability: Elements like hair color and individual growth differences can influence drug metabolite levels in hair.

Note: Despite being labeled as "hair follicle tests", the procedure actually evaluates the hair shaft, not the follicle beneath the skin.

Why Hair Follicle Testing Beats Urine Testing

In Coburn, PA, hair follicle testing is valued for its superior accuracy compared to traditional urine tests. While urine tests detect drug use shortly after intake, hair tests offer a broader lens, including past months.

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.
