Hair Follicle Drug Testing - Carlos, MN

What it is, How it works

Hair testing has emerged as a potent method for identifying drug and alcohol consumption. Hair offers a comprehensive history of alcohol and other drugs by capturing biomarkers within the strands as the hair grows. When collected near the scalp, hair can indicate consumption of alcohol and other drugs for up to about a 3-month period. Hair collection is straightforward, somewhat resistant to tampering, and easily transported.

A 1.5-inch sample of approximately 200 hair strands (comparable to a #2 pencil size) nearest the scalp yields 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen of 150mg is advised. We suggest weighing the sample using a jeweler’s scale. If scalp hair isn't available, an equivalent amount of body hair can be gathered. When mentioning head hair, we exclusively mean scalp hair. Body hair denotes all other types (e.g., facial, axillary).

Process Overview

There are four core steps in processing a drug test result in a laboratory: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves initially integrating a sample into a laboratory’s system. This step includes ensuring the sample was properly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry not imparted by an electronic chain of custody system.

Screening is a preliminary rapid evaluation for drugs of abuse. Though Screening is an economical approach for excluding drug usage in most samples, a positive result necessitates confirmation to be legally accepted in court. Presumptively positive samples during Screening must undergo a secondary confirmation.

Should a sample show a presumptive positive in the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. During this phase, drugs are extracted from hair at considerably lower concentrations than in alternative approaches (e.g., urine or oral fluid), thus making hair drug screening the most challenging technique to execute.

Confirmation for any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation, if necessary. The comprehensive laboratory process, from Accessioning to Confirmation, is scrutinized under both CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, contrary to urine tests that have a limited window.
• Challenging to cheat: It is highly challenging to falsify a hair drug test, resulting in more reliable outcomes.
• Historical insight: It can outline a drug use pattern over an interval, beyond just recent use.

Limitations:

• Fails to detect recent use: Detecting drugs in hair takes approximately 5-7 days.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Result variations: Elements such as hair color and individual differences in hair growth may influence drug metabolite concentrations within hair.

Note: Although frequently termed "hair follicle tests", the test itself examines the hair strand and not 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.
