Hair Follicle Drug Testing - Vermont Heights, FL

What it is, How it works

The use of hair testing is increasingly recognized as an effective method for identifying alcohol and drug use. Hair strands encapsulate biomarkers, providing a comprehensive long-term history of substance use. When sourced closely from the scalp, hair tests can offer up to a three-month detection span for alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and easy to transport.

Gathering a 1.5-inch specimen consisting of about 200 hair strands (similar in size to a #2 pencil) from the scalp yields about 100mg, the optimal quantity for both screening and confirmation purposes. For EtG, additional tests, or when testing more than 10 panels, a sample of 150mg is preferred. It is advisable to measure the sample on a jeweler’s scale. If scalp hair isn't available, collecting an equivalent amount of body hair is an option. "Head hair" specifically refers to scalp hair, while "body hair" covers all other types (like facial or axillary hair).

Process Overview

Four principal stages define the laboratory handling of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first step where a sample is entered into a laboratory system. This process verifies proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any outstanding data entry not included by an electronic chain of custody system.

Screening is a quick preliminary check for drugs. Although cost-effective for ruling out drug presence in most samples, a positive screening result must undergo confirmation to be valid in legal proceedings. Presumptively positive samples require a secondary confirmation.

In cases where Sampling is presumptively positive in the Screening phase, additional hair is taken from the original sample for Extraction. This stage involves drug extraction at lower concentrations than other methods (like urine or oral fluid), posing unique difficulties for hair drug screening as a methodology.

Confirmation, via GC/MS, GC/MS/MS, or LC/MS/MS, is executed on any positive screening outcome. Prior to confirmation, all presumptive positive samples are washed if necessary. The entire lab procedure, from Accessioning through Confirmation, adheres to both the CAP (College of American Pathologists) Hair standard and the ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug usage up to 90 days, whereas urine tests feature a smaller window.
• Resistant to tampering: The difficulty in cheating a hair drug test contributes to its accuracy.
• Provides usage history: Displays a drug use pattern over time, as opposed to recent usage only.

Limitations:

• Recent use undetectable: Drugs require approximately 5-7 days to be traceable in hair.
• Expense: Hair drug testing usually costs more than other methods.
• Result variability: Elements like hair color and individual hair growth distinctions can influence drug metabolite concentrations in hair.

Note: Commonly termed as "hair follicle tests," the assay 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.
