Hair Follicle Drug Testing - Chestnut Mound, TN

What it is, How it works

With its comprehensive capabilities, hair testing serves as a robust method for identifying drug and alcohol consumption. This technique utilizes hair’s ability to encapsulate biomarkers within its fibers, offering a longitudinal view of substance use. When acquired near the scalp, hair can reveal drug and alcohol presence over a span of roughly three months. Collecting hair is straightforward, tampering proves challenging, and transportation is convenient.

A segment of hair measuring 1.5 inches, consisting of about 200 strands (comparable to a #2 pencil width) near the scalp, yields 100mg of hair, which is the optimal amount for both screening and confirmation. For procedures involving EtG, ancillary tests, or over 10 panels, 150mg of the specimen is ideal. It’s advised to weigh the hair sample with a jeweler’s scale. In the absence of scalp hair, an equivalent volume of body hair may be utilized. Scalp hair specifically refers to hair from the head, whereas body hair includes all other types (such as facial or underarm hair).

Process Overview

There are four essential phases in the laboratory processing of drug test outcomes: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the sample's initial integration into the laboratory’s framework. This step ensures the sample's proper sealing and transport, allocates a LAN (Laboratory Accessioning Number) randomly, and fulfills any ancillary data requirements not handled by an electronic chain-of-custody system.

The Screening phase performs an expedited assessment for drug abuse markers. Although Screening is an economical approach to preliminarily exclude drug consumption across most samples, positive findings necessitate additional validation for legal admissibility. Samples yielding presumed positives in Screening must undergo further confirmation.

Upon a presumed positive indication during Screening, additional hair is extracted from the original sample for the Extraction phase. This stage isolates drugs from hair at notably diminished concentrations than other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.

For Confirmed results from screening, advanced techniques like GC/MS, GC/MS/MS, or LC/MS/MS are employed. Prior to confirmation, all samples presumptively positive undergo washing as required. The complete laboratory procedure, from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair designation and the compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use for as long as 90 days, whereas urine tests offer a reduced detection span.
• Minimal tampering risk: Hair drug testing is notably resistant to deception, ensuring result reliability.
• Longitudinal data provision: This method reveals a drug use history over time, not just recent consumption.

Limitations:

• Non-detection of recent usage: It typically requires 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug testing generally incurs higher costs than alternative testing methods.
• Result variability: Differences such as hair color and individual hair growth rates may impact drug metabolite levels detected within the hair.

Note: Commonly termed "hair follicle tests", this examination actually assesses the hair strand, 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.
