Hair Follicle Drug Testing - Lawler, MN

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair encapsulates a long-term profile of alcohol and drug usage by embedding biomarkers within the fibers as the hair strand grows. If collected near the scalp, hair offers an approximate 3-month timeframe for detecting alcohol and other drugs. Hair is straightforward to gather, relatively challenging to tamper with, and convenient for shipping.

A 1.5-inch segment of around 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp offers 100mg of hair, the optimal sample for both screening and confirmation. For EtG, add-ons, and/or tests beyond 10 panels, a sample amounting to 150mg is advised. We suggest measuring the specimen with a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be used. References to head hair specifically pertain to scalp hair. Body hair encompasses all other types of hair (such as facial, axillary, etc.).

Process Overview

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

Accessioning entails the initial integration of a sample into a lab’s system. This process includes validating the proper sealing and shipment of the sample, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data entry not included by an electronic chain of custody system.

Screening performs an initial swift examination for substance abuse. Although Screening is a cost-efficient approach to exclude drug usage in most samples, a positive screen must be verified for legal admissibility. Any samples exhibiting presumptive positives in Screening require further confirmation.

If a sample yields a presumptive positive in the Screening phase, additional hair is extracted from the initial specimen for Extraction preparation. In this stage, substances are extracted from hair at a concentration significantly lower than other methods (e.g., urine or oral fluid), making hair drug analysis the most challenging method to execute.

Confirmation of any positive screening result is implemented through GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation if necessary. The entire laboratory process from Accessioning to Confirmation is assessed according to both the CAP (College of American Pathologists) Hair specifications and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can identify drug usage for up to 90 days, contrasting with urine tests that have a shorter detection span.
• Hard to falsify: Exploiting a hair drug test is notably arduous, hence bolstering result reliability.
• Offers historical insights: It demonstrates a pattern of drug use throughout a period rather than merely recent usage.

Limitations:

• Inability to detect recent usage: Drugs take 5-7 days to manifest in hair.
• Expense: Hair drug tests tend to be pricier compared to other drug testing methods.
• Potential result variability: Variables such as hair color and individual hair growth differences can influence the concentration of drug metabolites found in hair.

Note: Although commonly termed as "hair follicle tests", the procedure examines 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.
