Hair Follicle Drug Testing - Oldtown, MD

What it is, How it works

Hair examinations are increasingly recognized as an effective means of identifying alcohol and drug usage. Hair retains an extensive record of substances by capturing biomarkers within the hair shaft itself. When gathered near the scalp, hair can offer approximately a 3-month retrospective window for drugs and alcohol usage. The collection is straightforward, has a moderate level of tamper resistance, and is conveniently transportable.

A 1.5-inch portion consisting of roughly 200 hair strands (comparable to the girth of a #2 pencil) near the scalp sums up to 100mg, which is considered the perfect sample for both initial and confirmatory testing. For EtG, supplementary, and/or tests exceeding 10 panels, a sample weighing 150mg is suggested. Utilizing a jeweler's scale for weighing is advisable. If head hair is insufficient, an equivalent portion of body hair can be procured. When we mention head hair, it pertains solely to scalp hair, while body hair encompasses all other types such as facial and axillary.

Process Overview

The quartet of pivotal stages in lab processing of a drug test outcome includes Accessioning, Screening, Extraction, and Confirmation.

Accessioning constitutes the preliminary processing of a specimen into the lab's framework. This stage ensures the sample's integrity by verifying its proper sealing and transportation, assigns a distinctive LAN (Laboratory Accessioning Number), and fills in any missing information absent from an e-chain of custody document.

Screening acts as an initial, swift assessment for illicit substances. Although Screening is a cost-efficient mechanism to dismiss drug use in the majority of cases, a reactive result demands subsequent confirmation for court admissibility. Samples that presumptively test positive during Screening necessitate further verification.

Should a testing sample yield a presumptive positive in Screening, additional hair is extracted from the main specimen to undergo Extraction. This phase involves extracting drugs from the hair at far lower concentrations compared to other testing methods (e.g., urine or oral fluid), thereby making hair drug screening a notably intricate procedure.

Confirmation of any positive screening results transpires via GC/MS, GC/MS/MS, or LC/MS/MS analyses. Before confirmation, all samples testing positive in preliminary screens are cleaned as required. The entire lab procedure from Accessioning to Confirmation complies with both the CAP (College of American Pathologists) standards for hair and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection span: Hair drug evaluations can identify drug use for durations up to 90 days, surpassing the shorter detection timeline of urine tests.
• Difficult to manipulate: Cheating a hair drug test is highly challenging, thereby enhancing reliability.
• Offers historical insight: This test provides insight into patterns of substance use over time, not solely recent consumption.

Limitations:

• Lacks immediacy: Drugs become detectible in hair roughly 5-7 days post-use.
• Expense: The financial outlay for hair drug testing more than other methodologies.
• Result variability: Aspects such as hair pigmentation and individual growth rate differences can influence metabolite levels.

Note: Commonly termed as "hair follicle tests", in reality, the analysis focuses on the hair shaft, not the follicle within 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.
