Hair Follicle Drug Testing - Wheeler, WA

What it is, How it works

Hair analysis is now regarded as an effective means for uncovering drug and alcohol consumption. The hair acts as a long-term record of alcohol and drugs by capturing biomarkers within the strands of growing hair. When procured near the scalp, hair can offer an approximately 3-month detection span for alcohol and other substances. Hair is straightforward to obtain, relatively challenging to tamper with, and convenient to transport.

A 1.5-inch portion consisting of roughly 200 hair strands (comparable to the size of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimum quantity for screening and confirmation. For EtG, supplementary tests, and/or analyses exceeding 10 panels, 150mg of the sample is advisable. It is suggested to weigh the hair using a jeweler's scale. If scalp hair is not accessible, a comparable amount of body hair can be gathered. Reference to head hair indicates only scalp hair. Body hair encompasses all other forms of hair (facial, axillary, etc.).

Process Overview

The key stages in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial incorporation of a sample into a lab's framework. This process includes ensuring the sample was properly sealed and dispatched, ascribing a random LAN (Laboratory Accessioning Number), and completing any further data input not provided by an electronic chain of custody system.

Screening provides a preliminary rapid check for misuse of drugs. While Screening is a cost-efficient method to dismiss drug use in most samples, a positive result needs verification for legal acceptance. All samples with presumptive positive results in Screening require subsequent confirmation.

In the event a sample indicates a presumptive positive during Screening, additional hair is extracted from the original sample for Extraction. Here, drugs are isolated from hair at notably lower concentrations than other methods (i.e., urine or oral fluid), which accounts for the higher complexity of hair drug screenings.

GC/MS, GC/MS/MS, or LC/MS/MS methods are employed to validate any positive screening outcomes. All samples with presumptive positive results are cleansed before confirmation if necessary. The lab procedures from Accessioning to Confirmation are evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection span: Hair drug tests can reveal drug usage up to 90 days, unlike urine tests which offer a shorter detection timeframe.
• Complexity to deceive: Cheating a hair drug test is notably difficult, enhancing result accuracy.
• Delivers historical insight: It offers a record of drug use patterns over time, beyond immediate use.

Limitations:

• Inability to detect recent use: Detectability of drugs in hair typically requires about 5-7 days.
• Expense: Generally, hair drug tests are costlier than alternative drug testing techniques.
• Result variability: Variables like hair color and individual hair growth differences can impact drug metabolite concentrations in hair.

Note: Although frequently termed "hair follicle tests", the analysis pertains to 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.
