Hair Follicle Drug Testing - Rolfe, IA

What it is, How it works

Hair analysis is increasingly regarded as an effective method for identifying drug and alcohol consumption. Hair captures a comprehensive history of alcohol and drug intake by embedding biomarkers within the fibers of the developing hair strand. When obtained near the scalp, hair can offer up to around a three-month detection period for alcohol and drugs. Hair is easy to gather, somewhat resistant to tampering, and straightforward to transport.

A 1.5-inch segment comprising roughly 200 hair strands (similar to the thickness of a #2 pencil) nearest the scalp will yield 100mg of hair, which is the ideal quantity for analysis and validation. For EtG, additional tests, and/or analyses beyond 10 panels, a 150mg sample is advisable. We suggest measuring the sample using a jeweler’s scale. If scalp hair is not accessible, an equivalent quantity of body hair may be used. When mentioning head hair, we mean scalp hair exclusively. Body hair refers to all other hair varieties (facial, axillary, etc.).

Process Overview

The four principal phases involved in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the initial handling of a sample within a lab’s framework. This involves confirming that the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not supplied by an electronic chain of custody system.

Screening includes a preliminary swift examination for abuse of drugs. Although Screening is an economical approach to exclude drug use in the majority of samples, a positive screen must be verified to be admissible in legal proceedings. Any samples that are presumptively positive in Screening necessitate secondary verification.

If a sample shows a presumptive positive in the Screening phase, more hair is extracted from the original specimen and processed for Extraction. In this stage, drugs are drawn out from hair at a considerably lower concentration than in other methods (e.g., urine or oral fluid), which is why hair drug testing is the most challenging technique to execute.

Verification of any positive screening outcome is performed through GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The entire laboratory process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can detect drug use for up to 90 days, unlike urine tests that have a shorter detection period.
• Challenge in falsifying results: It is notably challenging to falsify a hair drug test, which results in more precise outcomes.
• Delivers historical data: It can display a pattern of drug use over a period, not solely recent use.

Limitations:

• Inability to detect recent use: It takes approximately 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug evaluations are typically more costly than other drug testing techniques.
• Variability in outcomes: Factors such as hair color and individual variations in hair growth can influence the concentration of drug metabolites in the hair.

Note: Though often referred to as "hair follicle tests", the test itself 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.
