Hair Follicle Drug Testing - Francisco, IN

What it is, How it works

Hair analysis has gained recognition as an effective means for identifying the consumption of drugs and alcohol. Hair captures a long-term record of alcohol and drug use by embedding biomarkers within the fibers of the developing hair strand. When obtained near the scalp, hair can offer a detection window for alcohol and drugs up to about 3 months. Hair collection is straightforward, somewhat resistant to tampering, and convenient to transport.

A sample of 1.5 inches consisting of around 200 strands of hair (comparable to the size of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG tests, additional panels, or tests exceeding 10 panels, 150mg of the specimen is suggested. It is advisable to weigh the specimen using a jeweler's scale. In the absence of scalp hair, a similar quantity of body hair can be collected. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).

Procedure Overview

The four key stages in the laboratory assessment of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into a laboratory's framework. This involves confirming that the sample was appropriately sealed and sent, allocating a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.

Screening entails a preliminary swift evaluation for drugs of abuse. Although Screening is an economical method to eliminate drug usage from the majority of samples, a positive screen must be confirmed to be acceptable in a judicial context. Any samples indicating a positive result during Screening require a subsequent confirmation.

If a sample shows a positive indication in the Screening phase, additional hair is extracted from the initial specimen and prepared for Extraction. In this phase, drugs are isolated from hair at a significantly lower concentration than in alternative methods (such as urine or oral fluid), which is why hair drug analysis is recognized as the most challenging methodology to execute.

Any positive screening result is corroborated through GC/MS, GC/MS/MS or LC/MS/MS. All samples presumed to be positive are cleansed before confirmation as necessary. The entire laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Benefits of hair drug analysis:

• Extended detection period: Hair drug analysis can reveal drug use up to 90 days, whereas urine tests have a shorter detection period.
• Hard to falsify: Manipulating a hair drug analysis is highly challenging, thus ensuring more accurate results.
• Delivers historical information: It can display a pattern of drug usage over a duration, rather than just recent consumption.

Constraints:

• Incapable of identifying recent use: It requires approximately 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug analysis generally incurs higher costs than other drug testing methodologies.
• Result variability: Aspects such as hair color and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Although commonly called "hair follicle tests", the examination evaluates 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.
