Hair Follicle Drug Testing - Foster, OR

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a detailed record of substance use over time by encasing biomarkers in the hair strand's fibers. When taken near the scalp, hair offers an alcohol and drug detection timeline of up to around 3 months. Hair is straightforward to collect, relatively challenging to tamper with, and convenient to transport.

A hair sample of 1.5 inches, comprising around 200 strands (comparable to a #2 pencil's girth) near the scalp, yields 100mg of hair, optimal for both screening and confirmation. For assessments like EtG, add-ons, or panels exceeding 10, 150mg of hair is advocated. It is advisable to measure the hair on a jeweler’s scale. In the absence of scalp hair, an equivalent mass of body hair can be used instead. On the topic of head hair, we specifically mean scalp hair. Body hair encompasses all other types (such as facial or axillary hair).

Process Overview

The process of analyzing a drug test sample involves four crucial stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the phase where a sample is initially processed within a lab’s system. This consists of confirming the sample's proper sealing and shipment, assigning a randomized LAN (Laboratory Accessioning Number), and completing any supplementary data input not provided by an electronic chain of custody.

Screening is a preliminary, brief assessment for drug usage. Although Screening is cost-efficient for ruling out drugs in most samples, a positive result necessitates verification for court acceptability. Any samples with presumptive positives in Screening must undergo further confirmation.

For samples deemed presumptively positive during Screening, additional hair is extracted from the original specimen and readied for Extraction. During Extraction, drugs are isolated from hair at concentrations much lower than those in other methods (such as urine or oral fluids), which makes hair drug analysis one of the more challenging techniques.

Confirmation of positive screenings is performed using GC/MS, GC/MS/MS, or LC/MS/MS technologies. All presumptive positives are cleaned as necessary before confirmation. The entire process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests with shorter detection durations.
• High accuracy: Cheating on a hair drug test is highly challenging, ensuring more reliable results.
• Historical usage insight: Provides a usage pattern over time rather than just recent use.

Limitations:

• Recent use undetectable: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests tend to be more costly than alternative methods.
• Result variability: Factors like hair color and individual growth rates can impact metabolite concentration in hair.

Caution: Often called "hair follicle tests", the analysis actually examines the hair strand, not the follicle below the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Foster, OR, proves superior to urine testing for several reasons. While traditional urine tests detect recent drug use, hair tests offer extended detection periods, up to 90 days.

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.
