Hair Follicle Drug Testing - Buffalo Lake, MN

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. The fibers of hair capture biomarkers, offering a prolonged timeline of substance use as the strand grows. When collected near the scalp, it allows for a detection period of up to around three months for alcohol and drugs. Hair collection is straightforward, not easily tampered with, and convenient to send for testing.

A sample measuring 1.5 inches with close to 200 strands (equivalent in size to a #2 pencil) from the scalp provides around 100mg of hair, the optimal sample for testing and verification. For tests involving EtG, additions, and/or panels beyond ten, 150mg of hair is advisable. It is suggested to measure this using a jeweler’s scale. Should scalp hair be inaccessible, an equivalent volume of body hair can be used. "Head hair" refers specifically to scalp hair, while "Body hair" encompasses all others (e.g., facial, axillary).

Process Overview

There are four primary stages in lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial step of integrating a sample into a lab’s system. This step includes ensuring the sample is properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry not captured by an electronic chain of custody system.

Screening is a preliminary assessment for substance misuse. Although cost-effective for excluding drug use in most samples, a positive Screening result must be confirmed to be legally valid. Any samples indicating positive results in Screening need further confirmation.

If Screening results suggest a positive sample, additional hair is extracted from the initial sample for the Extraction process. This involves drug extraction from hair at much lower concentrations compared to other methods (e.g., urine, oral fluid), which is why hair drug testing is notably complex.

Confirmation of any positive Screening finding is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before Confirmation, all presumptive positive samples are cleansed as necessary. The complete process from Accessioning to Confirmation is subject to review based on the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use for up to 90 days, unlike urine tests with shorter detection periods.
• Hard to falsify: Cheating on a hair drug test is very challenging, enhancing result accuracy.
• Historical data provision: Provides a timeline of drug use rather than only detecting recent usage.

Limitations:

• Inability to detect recent use: Drugs in hair become detectable approximately 5-7 days after use.
• Expense: Generally, hair drug tests are costlier than other drug testing approaches.
• Result variability: Factors like hair color and personal variations in hair growth can influence drug metabolite concentration in hair.

Note: Although commonly called "hair follicle tests", the analysis targets the hair strand, not 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.
