Hair Follicle Drug Testing - Roeville, FL

What it is, How it works

The perception of hair testing has evolved into a crucial method for identifying drug and alcohol use, as hair provides a prolonged record of substance exposure by capturing biomarkers within the fibers of the hair as it grows. When strand samples are taken near the scalp, they can potentially indicate alcohol and drug consumption over a period extending up to three months. Hair samples are straightforward to gather, challenging to tamper with, and convenient for transportation.

Collecting a 1.5-inch segment consisting of roughly 200 hair strands closest to the scalp is ideal, as this will yield about 100mg of hair, sufficient for both screening and confirmation. For tests involving EtG, additional analytes, or more than 10 panels, a sample weighing 150mg is advised, with precise measurement recommended using a jeweler’s scale. If scalp hair isn't an option, an equivalent quantity of body hair can be collected. References to head hair specifically denote scalp hair. All other hair types, like facial or axillary, fall under the term body hair.

Process Overview

The laboratory drug testing comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is initially processed into the laboratory system, which involves ensuring the sample has been adequately sealed and shipped, allocating a unique LAN (Laboratory Accessioning Number), and entering any supplementary data not available via an electronic chain of custody.

Screening provides an initial, rapid assessment for drugs of abuse. Although Screening offers an economical way to rule out drug use in most samples, any positive results require Confirmation to be deemed court-admissible. Samples that test presumptively positive through Screening necessitate secondary confirmation.

In cases where Screening results are presumptively positive, more hair is extracted from the original sample for the Extraction phase. At this stage, drugs are isolated from hair at a lower concentration compared to other methods (such as urine or oral fluid tests), marking hair drug testing as a methodological challenge.

When Confirmation is necessary for positive Screening results, methods like GC/MS, GC/MS/MS, or LC/MS/MS are employed. Presumptively positive samples undergo washing before Confirmation if needed. The entire procedure from Accessioning to Confirmation is closely scrutinized under standards set by both the CAP (College of American Pathologists) Hair program and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair testing can reveal drug use for a period reaching 90 days, whereas urine testing provides a shorter timeframe.
• Challenge to deceive: The complexity of evading a hair drug test translates to more dependable results.
• Historical insights: Hair tests offer a timeline of drug use history, beyond immediate usage.

Limitations:

• Recent use undetectable: Drugs become traceable in hair only after an estimated 5-7 days post-consumption.
• Expense: Hair drug testing tends to incur higher costs than other methods.
• Result variability: Factors like hair color and individual growth rates can influence drug metabolite concentration in hair strands.

Note: Commonly misidentified as "hair follicle tests", the analysis focuses on the hair strand, not the scalp-embedded follicle.

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.
