Hair Follicle Drug Testing - Walthall, MS

What it is, How it works

Seen as a significant mechanism for detecting drug and alcohol consumption, hair testing showcases its potency. By enclosing biomarkers within hair strands as they grow, hair offers a prolonged timeline of alcohol and drug use. When gathered near the scalp, hair can reveal a detection timeframe extending up to 3 months for alcohol and drugs. Hair collection is straightforward, with minimal potential for tampering, and convenient for shipping.

A hair sample measuring 1.5 inches, typically around 200 strands (equivalent to the circumference of a #2 pencil) nearest the scalp yields 100mg, which is ideal for screening and confirmation. For tests such as EtG, additional panels, or those exceeding 10, a specimen quantity of 150mg is advised. Precision weighing using a jeweler’s scale is recommended. Should scalp hair be unavailable, a similar quantity of body hair can be used. When referencing head hair, the term pertains solely to scalp hair. Body hair encompasses all other types (e.g., facial, axillary).

Process Overview

In processing a drug test outcome within the lab, four primary steps are involved: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial entry of a sample into a lab's system. This step confirms proper sealing and shipping of the sample, allocates a random LAN (Laboratory Accessioning Number), and finalizes any outstanding data inputs absent from an electronic custody chain.

Screening is utilized for a preliminary review for drugs. The affordability of Screening makes it ideal for negating drug use across numerous samples; however, to render positive results court-acceptable, further confirmation is indispensable. Samples returning a presumptive positive from Screening must undergo additional confirmation.

With a presumptive positive outcome from Screening, additional hair is sourced from the initial sample for the Extraction phase. Here, drugs are withdrawn from hair at notably reduced concentrations than alternative methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

GC/MS, GC/MS/MS, or LC/MS/MS are employed for confirming any positive findings from Screening. Presumptive positives necessitate washing before confirmation, as required. The complete laboratory process, from Accessioning to Confirmation, is reviewed in compliance with both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use up to 90 days, surpassing urine tests with shorter detection spans.
• Challenge to manipulate results: Hair drug tests are challenging to falsify, increasing result credibility.
• Offers historical insight: They reveal a pattern of drug use over time, beyond mere recent consumption.

Limitations:

• Lacks detection of recent use: Drugs need roughly 5-7 days to become detectable in hair.
• Expense: Typically, hair drug tests incur higher costs than other testing methods.
• Result variations: Hair color and individual hair growth rates can influence metabolite concentrations in hair.

Note: Despite the common term "hair follicle tests", the analysis focuses on the hair strand rather than the 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.
