Hair Follicle Drug Testing - Riley, IN

What it is, How it works

Hair assessments have emerged as an effective method for detecting substance and alcohol consumption. Hair captures a long-range record of alcohol and drug use by embedding biomarkers into the strands as they grow. When taken near the scalp, hair samples can showcase substance use for a duration of up to three months. Hair is easy to collect, challenging to tamper with, and convenient to transport.

A 1.5-inch portion of roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg, which is optimal for both preliminary and confirming analysis. For tests like EtG add-ons and those requiring more than ten panels, 150mg is suggested. Using a jeweler's scale for weighing the sample is advisable. If head hair is absent, an equivalent amount of body hair may be gathered. Head hair pertains solely to scalp hair, while body hair includes all other hair categories (like facial or underarm).

Process Overview

The laboratory processing of drug test results involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial phase where a sample is integrated into a laboratory’s workflow. It entails verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and handling any supplementary data not covered by an electronic chain of custody.

During Screening, an initial assessment for substance abuse is conducted. Though cost-effective for ruling out drug use in most samples, a positive screen needs confirmation to stand up in a legal setting. Presumptive positive samples necessitate a secondary test.

In cases of presumptive positivity during Screening, additional hair is extracted from the primary sample for the Extraction phase. In this step, substances are isolated from the hair at concentrations much lower than other methods (e.g., urine or saliva), making hair drug assessments more complex.

Confirming a positive result is done using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, samples presumed positive are washed as required. The entire procedure, from Accessioning to Confirmation, adheres to CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 certification.

Advantages of hair drug testing:

• Extended detection range: Hair tests identify drug usage for up to 90 days, surpassing the shorter detection periods of urine tests.
• Challenging to manipulate: Hair tests have a high accuracy as they are difficult to adulterate.
• Offers historical insights: It allows tracking drug use patterns over time rather than just recent usage.

Limitations:

• Not ideal for recent use detection: Drugs become traceable in hair only after about 5-7 days.
• Expense: Hair testing generally incurs higher costs than other testing methods.
• Result variability: Factors such as hair color and individual growth differences can influence metabolite concentrations.

Note: Often called "hair follicle tests", these evaluations focus on 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.
