Hair Follicle Drug Testing - Au Gres, MI

What it is, How it works

Hair testing is highly regarded as an effective method for identifying drug and alcohol usage. Hair captures biomarkers along the fiber of the growing strand, presenting a prolonged timeline for detecting alcohol and drug use. When trimmed near the scalp, the hair offers a detection window of up to three months. This method is straightforward to gather, challenging to tamper with, and convenient to transport.

Taking a 1.5-inch cut of roughly 200 strands (about as thick as a #2 pencil) nearest to the scalp yields 100mg, which is the optimal sample size for analysis. For EtG, additional tests, or those exceeding 10 panels, a specimen quantity of 150mg is advisable. It is suggested to use a jeweler’s scale for weighing the specimen. If scalp hair is absent, a proportional quantity of body hair is an acceptable substitute. The term head hair pertains exclusively to scalp hair, whereas body hair encompasses all other growths (facial, axillary, etc.).

Process Overview

There are four pivotal steps undertaken in the laboratory processing of drug test results: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial stage wherein the sample is incorporated into the lab’s system. This step involves ensuring the sample is adequately sealed and shipped, assigning a Laboratory Accessioning Number (LAN), and entering any additional data absent from an electronic chain of custody.

Screening pertains to a preliminary rapid assessment for illicit substances. Although cost-effective for negating drug presence in most samples, a positive screen demands validation to hold up in legal settings. Any sample showing a presumptive positive during Screening requires further confirmation.

In instances of a presumptive positive result from Screening, additional hair is drawn from the sample for Extraction. At this stage, drug concentration is extracted at significantly lower levels than other methods (e.g., urine or oral fluid), illustrating the complexities of hair drug screening.

Verification of any positive screening outcome is executed through techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all samples with presumptive positive results undergo necessary washing. The comprehensive laboratory procedure from Accessioning through Confirmation adheres to the CAP (College of American Pathologists) Hair designation alongside accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection: Hair drug testing reveals drug use history for up to 90 days, unlike urine testing which offers a limited timeframe.
• Hard to manipulate: Cheating a hair drug test is exceptionally challenging, thus yielding more reliable results.
• Presents historical trends: Enables the showcasing of usage patterns over a significant time span, not merely recent consumption.

Limitations:

• Incapable of detecting recent consumption: Drugs take 5-7 days to become traceable in hair.
• Expense: Hair drug testing incurs higher costs compared to other testing methodologies.
• Result variations: Elements such as hair coloration and individual variation in hair growth can influence drug metabolite levels within hair.

Note: Although frequently termed as "hair follicle tests", the examination itself 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.
