Hair Follicle Drug Testing - Tempiute, NV

What it is, How it works

Hair testing is recognized as a robust method for detecting drug and alcohol consumption. Hair encapsulates a comprehensive history of alcohol and drug usage by sealing biomarkers within the strands as they grow. By taking hair samples near the scalp, it’s possible to obtain a detection timeframe of roughly three months for alcohol and drugs. Collecting hair is straightforward, relatively tamper-proof, and easy to transport.

A 1.5-inch segment containing around 200 hair strands (equivalent to a #2 pencil in thickness) near the scalp yields 100mg, which is the optimal quantity for testing and validation. For EtG, add-ons, or tests exceeding 10 panels, a 150mg specimen is suggested. We advise weighing the sample using a jeweler’s scale. If scalp hair is not accessible, a similar quantity of body hair can be gathered. When mentioning head hair, it pertains solely to scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial integration of a sample into the laboratory’s system. This step verifies that the sample was correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and handles additional data entry beyond what an electronic chain of custody system provides.

Screening conducts a preliminary assessment for substances of abuse. Although Screening is a cost-efficient approach to dismiss drug use in most samples, a positive screen needs further confirmation to be legally admissible. Samples that are presumptively positive in Screening require secondary confirmation.

If a sample is preliminarily positive in the Screening phase, additional hair is extracted from the original sample and prepped for Extraction. During this phase, drugs are removed from hair at a significantly lower concentration compared to other methods (such as urine or oral fluid), which makes hair drug screening one of the most complex methodologies.

Confirmation for any positive screening results is accomplished via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The entire lab process from Accessioning to Confirmation is scrutinized under both 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 tests can identify drug usage extending up to 90 days, unlike urine tests which have a shorter detection timeframe.
• Challenge to cheat: Cheating a hair drug test is quite challenging, enhancing the accuracy of the results.
• Offers historical insight: It reveals a timeline of drug use over an extended period, not merely recent use.

Limitations:

• Cannot detect recent consumption: It takes roughly 5-7 days for substances to become measurable in hair.
• Expense: Hair drug tests are typically costlier than other drug testing techniques.
• Result variations: Elements such as hair color and personal hair growth variability can influence drug metabolite concentration in the hair.

Note: Although often termed as "hair follicle tests", the test itself examines the hair strand rather than the hair 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.
