Hair Follicle Drug Testing - Marion Hill, PA

What it is, How it works

As an effective approach for identifying substance and alcohol consumption, hair testing is highly regarded. By embedding biomarkers within the hair strand's fibers, hair can reveal extensive histories of alcohol and drug use. When collected near the scalp, hair can offer up to a 3-month detection period for both alcohol and drugs. Collecting hair is uncomplicated, relatively tamper-proof, and convenient to transport.

Gathering a 1.5-inch segment of around 200 hairs (roughly the width of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal amount for screening and confirmation tests. For EtG, additional tests, and/or beyond 10-panel screenings, a 150mg sample is advisable. We suggest using a jeweler’s scale for weighing the specimen. If scalp hair is unavailable, an equivalent quantity of body hair may be collected. References to head hair specifically denote scalp hair. Body hair covers all other types (facial, axillary, etc.).

Process Overview

Laboratory processing of a drug test result encompasses four main steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial sample intake process within a laboratory’s system. This procedure ensures the sample is sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry not covered by an electronic chain of custody system.

Screening entails a rapid initial assessment for illicit substances. While a cost-effective method to exclude drug use in most samples, a positive screen requires confirmation to be legal in court. Any samples tentatively positive in Screening necessitate further confirmation.

Should a sample show presumptive positive results during Screening, additional hair is extracted from the original specimen for the Extraction phase. Here, drugs are extracted from hair at concentrations lower than other methods (e.g., urine or oral fluids), making hair drug screening exceptionally challenging to execute.

Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The entire laboratory process, from Accessioning to Confirmation, is thoroughly reviewed under the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests identify drug use for as long as 90 days, whereas urine tests have a shorter detection timeframe.
• Hard to tamper: It's highly challenging to manipulate a hair drug test, ensuring more accurate results.
• Supplies backdated data: It demonstrates a drug use pattern over time rather than just recent use.

Limitations:

• Inability to determine recent consumption: Drugs take approximately 5-7 days to materialize in hair.
• Expense: Hair drug tests are generally costlier than alternative testing methods.
• Result variance: Hair color and individual hair growth variations can influence the concentration of drug residues in hair.

Note: While frequently labeled as "hair follicle tests", the examination itself targets the hair strand, 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.
