Hair Follicle Drug Testing - Scaly Mountain, NC

What it is, How it works

Over time, hair testing has emerged as a significant asset in identifying alcohol and drug use. Hair serves as a chronicled record for alcohol and drugs by embedding biomarkers within the strands of hair that are actively growing. When obtained near the scalp, such hair can offer a detection window for substances lasting up to roughly 3 months. The collection process for hair is straightforward, it is fairly resistant to tampering, and it is convenient to transport.

A sample measuring 1.5 inches comprised of roughly 200 hair strands (comparable to the girth of a #2 pencil) nearest to the scalp amounts to 100mg of hair, which is the optimal sample size for screening and subsequent confirmation. For EtG, additional testing, or extensive panel tests beyond 10, a specimen of 150mg is suggested. It is advisable to use a jeweler’s scale for weighing the sample. If scalp hair isn’t available, an equivalent portion of body hair can be obtained. When we refer to head hair, it implies scalp hair specifically. Body hair encompasses all other varieties (such as facial, axillary, etc.).

Process Overview

The laboratory processing of drug tests is structured into four crucial phases: Accessioning, Screening, Extraction, and Confirmation.

The Accessioning step involves incorporating a sample into the laboratory’s workflow. This step entails ensuring that the sample has been appropriately sealed and transported, allocating a random LAN (Laboratory Accessioning Number), and addressing any outstanding data input not covered by an electronic custody system.

The Screening phase is a preliminary, efficient assessment for the presence of illicit substances. Although Screening is a cost-effective method to dismiss drug presence in many samples, a positive Screen must be corroborated for court validity. Any Screening-positive samples necessitate subsequent confirmation.

Upon receiving a presumptive positive result during Screening, additional hair is extracted from the initial sample for the Extraction process. Here, drugs are extracted from hair at notably lower concentrations than seen in alternative techniques (e.g., urine or oral fluid), highlighting why hair drug testing is a complex procedure.

The Confirmation stage of any screening-positive result is executed utilizing GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing as necessary before confirmation. The entirety of the laboratory's process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation, along with ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair tests can identify drug use extending to 90 days, while urine tests have a briefer detection period.
• Nearly impossible to falsify: Cheating on a hair drug test is extremely challenging, enhancing result reliability.
• Historic data provision: It can outline a trend of drug use over a significant timeframe as opposed to current use only.

Limitations:

• Inability to capture recent use: Drugs take about 5-7 days to become detectable in hair.
• Expense: Generally, hair drug tests entail greater costs compared to other testing methodologies.
• Outcome discrepancies: Factors such as hair pigmentation and individual hair growth rates can influence metabolite concentrations within the hair.

Note: Often termed as "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. 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.
