Hair Follicle Drug Testing - Toad Hop, IN

What it is, How it works

Recognized as a robust method for uncovering drug and alcohol consumption, hair testing offers a comprehensive timeline of substance use by encasing biomarkers within the hair strand's fibers during growth. By obtaining hair samples near the scalp, one can achieve a detection span of up to roughly 90 days for substances. Hair collection is straightforward, challenging to tamper with, and easy to transport.

Securing a 1.5-inch segment of roughly 200 hair strands (comparable to the thickness of a #2 pencil) adjacent to the scalp yields 100mg of hair, an ideal quantity for both preliminary screening and validation. For tests involving EtG, additional panels, or more than 10 panels, a 150mg specimen is advisable. Using a jeweler’s scale to gauge the specimen is suggested. If scalp hair isn't available, an equivalent quantity of body hair may be used. Here, head hair refers solely to scalp hair, while body hair encompasses all other types (like facial and axillary hair).

Process Overview

The laboratory drug test result processing involves four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the preliminary incorporation of a sample into the lab's database. This phase includes ensuring the sample's proper sealing and shipping, assigning it a random LAN (Laboratory Accessioning Number), and completing any extra data entry tasks absent from an electronic chain of custody system.

Screening entails an initial rapid assessment for drug use. Although Screening provides a cost-efficient means to exclude drug use for most samples, any positive screenings must undergo confirmation to be court-admissible. Samples testing presumptively positive during Screening need a secondary validation.

Any sample showing presumptive positivity in the Screening phase undergoes further hair extraction from the original specimen, preparing it for Extraction. In this phase, the drugs are extracted from hair at significantly lower concentrations compared to other methods (like urine or oral fluids), emphasizing the complexity of hair drug testing methodologies.

Each positive screening result is confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are washed as necessary. The comprehensive laboratory workflow from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days prior, whereas urine tests cover shorter periods.
• Resistance to tampering: Hair drug tests are notably resistant to manipulation, ensuring more accurate results.
• Chronological data provision: This method can reveal drug use patterns over time, unlike tests detecting only recent usage.

Limitations:

• Incapacity for detecting immediate use: Detecting drugs in hair requires approximately 5-7 days post-use.
• Expense: Hair drug tests are typically pricier compared to alternative drug testing methods.
• Result variability: Aspects like hair color and personal hair growth differences may sway the concentration of drug metabolites in hair.

Note: Often termed as "hair follicle tests," these tests focus on analyzing 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.
