Hair Follicle Drug Testing - Wolf, KS

What it is, How it works

Hair testing is recognized as an effective means for detecting drug and alcohol consumption. Hair captures a historical record of alcohol and drugs by embedding biomarkers within the hair's fibers. When sourced from near the scalp, hair can offer a detection span for alcohol and drugs extending to roughly three months. Collection of hair is straightforward, tampering is relatively challenging, and shipping is uncomplicated.

A 1.5-inch segment comprising around 200 hair strands (comparable to the thickness of a #2 pencil) at the closest point to the scalp yields 100mg, which is the optimal quantity for assessment and verification. For EtG, supplementary, and/or tests exceeding 10 panels, 150mg of the sample is advisable. It's suggested to measure the sample using a jeweler’s scale. In circumstances where scalp hair is inaccessible, a proportional amount of body hair may be gathered. Reference to head hair solely denotes scalp hair. Body hair pertains to all other types, such as facial and axillary hair.

Process Overview

The laboratory processing of a drug test result includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the preliminary processing of a sample into the laboratory’s system. It involves confirming the appropriate sealing and shipment of the sample, allocating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data input absent in an electronic chain of custody system.

Screening constitutes an initial examination for substances of abuse. While cost-effective, Screening serves to disprove drug consumption in the majority of cases; however, a positive screen mandates confirmation for court admissibility. Any samples indicating a positive result during Screening necessitate an additional confirmation.

In the event of a presumptive positive sample during Screening, additional hair is retrieved from the initial sample and prepared for Extraction. In this phase, drugs are isolated from hair at significantly reduced concentrations compared to other methods (e.g., urine or oral fluid), rendering hair drug screening a more complex procedure to conduct.

Confirmation of any positive screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples suspected to be positive undergo washing prior to confirmation as required. The complete laboratory process ranging from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a limited detection timeframe.
• Challenging to manipulate: It is highly challenging to deceive a hair drug test, ensuring more reliable outcomes.
• Delivers historical insight: It offers a usage pattern over time, and not just recent usage.

Limitations:

• Inability to identify recent use: Approximately 5-7 days are required for drugs to become detectable in hair.
• Expense: Hair drug tests are typically pricier compared to alternative drug testing methods.
• Result variability: Elements like hair color and individual hair growth differences can influence the concentration of drug metabolites within the hair.

Note: Commonly termed as "hair follicle tests", this test evaluates 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.
