Hair Follicle Drug Testing - Trappe, MD

What it is, How it works

Hair analysis is now viewed as an effective means for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and various substances by embedding biomarkers within the strands' fibers as they grow. When clipped at the scalp, hair can offer up to a three-month detection timeframe for alcohol and drugs. Hair collection is easy, tampering is challenging, and it is straightforward to send by mail.

An ideal sample comprises a 1.5-inch length of roughly 200 hair strands (equivalent to a #2 pencil width) near the scalp, yielding 100mg of hair, optimal for testing. For EtG and advanced tests beyond 10-panel, a 150mg specimen is suggested. We advise using a jeweler's scale to verify the specimen's weight. Should there be a lack of scalp hair, an equivalent quantity of body hair can be gathered. "Head hair" specifies scalp hair only, while "body hair" includes all other types (facial, underarm, etc.).

Process Overview

The laboratory processing for drug test results consists of four primary procedures: Accessioning, Screening, Extraction, and Confirmation.

The Accessioning step processes a sample initially into the laboratory's system. Tasks include ensuring the sample's secure sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and entering any supplementary information not covered by electronic custody systems.

The Screening phase provides a preliminary assessment for substances of abuse. Although it is an economically efficient method for ruling out drug use in most specimens, positive screening outcomes must be verified for legal validity. Any presumptive positive samples at the Screening stage necessitate further confirmation.

When a sample tests presumptively positive during Screening, additional hair is taken from the original sample for Extraction. Here, drugs are isolated from hair at significantly lower concentrations than other approaches (e.g., urine or saliva tests), explaining why hair drug screening is among the most challenging methodologies to execute.

For Verification of any positive screening results, GC/MS, GC/MS/MS, or LC/MS/MS methods are employed. All samples with presumptive positive results undergo washing before confirmation when necessary. The complete laboratory process, from Accessioning through Confirmation, adheres to the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Unlike urine tests, hair drug testing can reveal drug usage up to 90 days prior.
• Challenging to fake: The accuracy of hair drug tests is enhanced by being hard to tamper with.
• Delivers historical patterns: Offers an account of drug consumption trends over time, beyond just recent use.

Limitations:

• Doesn't identify very recent use: Drugs become detectable in hair approximately 5-7 days after usage.
• Expense: Hair drug testing is typically pricier than alternatives.
• Result variability: Hair color and personal growth differences can impact drug metabolite levels in hair.

Note: Frequently referred to as "hair follicle tests," this method actually examines 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.
