Hair Follicle Drug Testing - Du Quoin, IL

What it is, How it works

Hair assessments have increasingly been recognized as a strong instrument in identifying drug and alcohol consumption. Hair offers an extensive record of alcohol and drugs by capturing biomarkers within the fibers of the developing hair strand. When collected near to the scalp, hair can offer up to an approximate three-month detection period for alcohol and other substances. Hair is easy to gather, somewhat resistant to tampering, and straightforward to transport.

A 1.5-inch portion of around 200 strands of hair (roughly the size of a #2 pencil) nearest the scalp will yield 100mg of hair, which is the optimal amount for screening and validation. For EtG, extra tests, and/or assessments over ten panels, 150mg of the sample is advised. It's suggested to weigh the sample on a jeweler’s scale. If scalp hair is not available, a corresponding quantity of body hair may be used. When we mention head hair, we refer specifically to scalp hair. Body hair refers to all other types (facial, axillary, etc.).

Process Overview

The four key steps in the laboratory analysis of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the preliminary handling of a sample within a laboratory’s system. This step involves verifying that the sample was sealed and dispatched correctly, allocating a random LAN (Laboratory Accessioning Number), and completing any additional data inputs not covered by an electronic chain of custody system.

Screening entails a preliminary rapid check for drugs. Though Screening is a cost-efficient means to exclude drug use for the majority of samples, a positive screen requires confirmation to be valid in legal settings. All samples that are tentatively positive in Screening necessitate a secondary confirmation.

If a specimen is found tentatively positive during the Screening phase, additional hair is taken from the initial sample and readied for Extraction. During this stage, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), thereby making hair drug assessment one of the most challenging methodologies.

Confirmation of any screening positive result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All tentative positive samples undergo washing before confirmation as required. The entire laboratory procedure from Accessioning to Confirmation is supervised under both CAP (College of American Pathologists) Hair designation and the accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug evaluations can detect substance use up to 90 days, contrary to urine tests which have a shorter detection span.
• Challenging to deceive: It is quite difficult to circumvent a hair drug evaluation, thus enhancing result accuracy.
• Yields historical insight: It can reveal a pattern of substance use over time, rather than merely recent consumption.

Limitations:

• Cannot detect recent usage: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug evaluations are generally pricier than other drug testing methods.
• Result variations: Factors like hair color and individual discrepancies in hair development can influence drug metabolite concentrations in hair.

Note: Though often termed "hair follicle tests", the analysis targets the hair strand itself and not 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.
