Hair Follicle Drug Testing - Carlton, MT

What it is, How it works

Hair analysis is now recognized as an effective method for identifying the presence of drugs and alcohol. Hair captures a prolonged timeline of substance intake due to the preservation of biomarkers in the strands of growing hair. When sourced close to the scalp, a hair sample can offer a detection span of up to three months for alcohol and drugs. The collection process for hair is straightforward, challenging to tamper with, and easy to transport.

A sample consisting of 1.5 inches of roughly 200 hair strands (the approximate diameter of a standard pencil) next to the scalp yields 100mg of hair, which is the optimal quantity for thorough screening and verification. For tests involving EtG, add-ons, and/or those exceeding 10 panels, a specimen of 150mg is advisable. It is suggested to measure the sample using a jeweler's scale. If scalp hair isn’t available, an equivalent quantity of body hair can be gathered. "Head hair" pertains exclusively to scalp hair, while "body hair" encompasses other hair types (facial, axillary, etc.).

Process Overview

There are four key stages in a laboratory's process for analyzing a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where the sample is entered into the lab's system. This step confirms the sample was securely sealed and shipped, assigns it a random Laboratory Accessioning Number (LAN), and completes any data entry omitted by the electronic chain of custody.

Screening provides a rapid assessment for the presence of drugs. Although cost-effective as a preliminary test to exclude drug use in numerous samples, any positive result in Screening requires further confirmatory testing to be valid in a legal context. Samples that yield positive results in Screening subsequently require Confirmation.

For those samples that test positive during Screening, additional hair is extracted from the initial sample and processed in the Extraction stage. Here, drugs are separated from hair at much lower concentrations than other methods, such as urine or oral fluid testing, which is why hair drug testing is technically complex.

Confirmation for any positive Screening results employs techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all positive samples are thoroughly cleaned as needed. The laboratory process from Accessioning to Confirmation is conducted per both the College of American Pathologists (CAP) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a more limited detection period.
• Challenging to manipulate: The accuracy of hair drug testing is heightened due to its resistance to cheating.
• Tracks long-term usage: Hair tests can outline a timeline of drug use over several months, not merely recent usage.

Limitations:

• Cannot detect recent usage: There is a delay of about 5 to 7 days before drugs become detectable in hair.
• Expense: Hair drug tests generally incur higher costs compared to other testing methods.
• Result variability: Elements like hair color and personal differences in hair growth can influence drug metabolite levels in hair.

Note: Despite common references to "hair follicle tests", the analysis actually examines the hair strands rather than the follicles situated 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented.
