Hair Follicle Drug Testing - Spencer, IA

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. By embedding biomarkers within the strands, hair retains a long-term record of alcohol and other drug usage. When hair is cut near the scalp, it can reveal alcohol and drug use for up to about three months. Collecting hair is straightforward, it is relatively resistant to tampering, and it is easy to transport.

A sample measuring 1.5 inches composed of around 200 strands (comparable to the thickness of a #2 pencil) closest to the scalp provides 100mg of hair, which is the perfect amount for both screening and confirmation. For EtG, additional tests, and/or those exceeding 10 panels, 150mg is preferable. We advise weighing the specimen using a jeweler's scale. If scalp hair is unavailable, a similar quantity of body hair can be used. "Scalp hair" specifically refers to hair from the head, while "body hair" encompasses all other hair types (facial, underarm, etc.).

Process Overview

The main stages of lab processing for a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial phase of integrating a sample into the lab's system. This step ensures that the sample was appropriately sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data not covered by an electronic chain of custody.

Screening is a preliminary rapid evaluation for drugs of abuse. While Screening is a budget-friendly method to eliminate drug presence in most samples, a positive result requires further confirmation for legal admissibility. Any samples that appear positive during Screening need a secondary confirmation.

Should a sample appear positive in the Screening phase, additional hair is taken from the original specimen and prepped for Extraction. Here, drugs are isolated from hair at much lower concentrations than other techniques (like urine or oral fluid), thus making hair drug screening particularly challenging.

Confirmation of any positive Screen findings is done through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, all presumptively positive samples undergo washing as necessary. The comprehensive lab process from Accessioning through Confirmation is overseen in accordance with the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests identify drug usage for up to 90 days, unlike urine tests that have a more limited timeframe.
• Low chance of manipulation: It is considerably challenging to falsify a hair drug test, ensuring more precise outcomes.
• Supplies historical usage data: It helps provide an insight into drug usage patterns over a duration, beyond just recent consumption.

Limitations:

• Inability to spot recent use: Drugs require about 5-7 days after use to become traceable in hair.
• Expense: Hair drug tests generally cost more than alternative drug test methods.
• Result variability: Elements such as hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although commonly termed "hair follicle tests," the procedure examines the hair strand, not the beneath-the-scalp hair 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing.
