Hair Follicle Drug Testing - Oma, AR

What it is, How it works

Hair testing has emerged as a significant method for identifying the usage of drugs and alcohol. Hair retains a comprehensive record of alcohol and drug exposure, encapsulating biomarkers within the strand's fibers as it grows. When gathered in proximity to the scalp, a hair sample can reveal drug and alcohol usage up to around a 90-day timeframe. The collection process for hair is straightforward, relatively tamper-resistant, and convenient for shipping.

A sample measuring 1.5 inches, comprising roughly 200 strands (akin to the thickness of a #2 pencil) near the scalp, results in 100mg of hair, which is optimal for both screening and verification. For EtG, supplementary tests, or analyses beyond 10 panels, a sample of 150mg is suggested. Using a jeweler’s scale for weighing is advisable. In cases where scalp hair cannot be obtained, an equivalent quantity of body hair is acceptable. The term head hair specifically denotes scalp hair. Body hair encompasses all other types, including facial and axillary.

Process Overview

There are four primary stages in the laboratory processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial incorporation of a sample into a laboratory's framework. This step ensures the sample is securely sealed and correctly sent, assigns a unique LAN (Laboratory Accessioning Number), and concludes any additional data recording not included in an electronic custody system.

Screening is a preliminary quick assessment for drug abuse. Although Screening offers an economical approach to dismiss drug consumption in the bulk of samples, a court-accepted positive result must undergo confirmation. Presumptively positive Screening samples require subsequent verification.

Upon a presumptive positive result in the Screening phase, additional hair is extracted from the original sample to prepare for Extraction. Drugs are drawn from hair at far lower concentrations here than other methods like urine or oral fluid; thus, making hair drug screening particularly challenging.

Any positive results from screening are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS procedures. Prior to confirmation, presumptive positives undergo necessary washing. The comprehensive laboratory workflow from Accessioning to Confirmation is consistently monitored under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Lengthy detection period: Hair drug tests can identify drug consumption for up to 90 days, in contrast to urine tests with a briefer detection period.
• Hard to deceive: Cheating a hair drug test is notably challenging, thereby enhancing result accuracy.
• Historical insight: It offers a timeline of drug usage over a substantial period, unlike merely identifying recent use.

Limitations:

• Inability to spot recent usage: Drugs become detectable in hair approximately 5-7 days after usage.
• Expense: Hair drug testing generally incurs higher costs compared to other testing alternatives.
• Result variability: Aspects like hair color and individual growth differences can influence metabolite concentration levels in hair.

Note: Although often termed as "hair follicle tests", the analysis targets the hair strand itself, not the follicle under the skin.

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.
