Hair Follicle Drug Testing - Venango, NE

What it is, How it works

Considered an effective method for identifying drug and alcohol consumption, hair testing offers a comprehensive view of substance use history by capturing biomarkers within the strands of growing hair. When gathered near the scalp, hair can provide a detection window for alcohol and other substances of up to approximately three months. Hair is easy to collect, somewhat challenging to tamper with, and straightforward to transport.

A sample measuring 1.5 inches with around 200 strands of hair (comparable to the size of a #2 pencil) taken from the scalp will yield 100mg, the optimal amount for screening and verification. For EtG, additional tests, and assessments exceeding 10 panels, 150mg of the sample is advised. We suggest weighing the sample on a jeweler's scale. In the absence of scalp hair, an equal quantity of body hair can be used. When mentioning head hair, we refer specifically to scalp hair, while body hair encompasses all other types (face, underarms, etc.).

Process Overview

The primary steps in laboratory processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves initially processing a sample into the laboratory's system, ensuring it was sealed and transported correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data not covered by an electronic chain of custody.

Screening involves a preliminary check for drugs of abuse. Although cost-effective for ruling out drug use in the majority of samples, a positive screen requires confirmation to be legally permissible. Any samples that test presumptively positive during Screening need a secondary confirmation.

In cases where a sample tests presumptively positive at the Screening stage, additional hair from the initial sample is prepared for Extraction. At this stage, drugs are extracted from hair at significantly lower concentrations than in methods such as urine or oral fluids, explaining why hair drug screening is one of the more challenging methodologies.

Confirmation of any positive screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. The entire laboratory procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests identify drug use for up to 90 days, compared to the shorter detection period of urine tests.
• Challenging to deceive: It’s extremely difficult to cheat a hair drug test, enhancing the accuracy of results.
• Offers historical insights: It can reveal a pattern of drug use over time, not merely recent consumption.

Limitations:

• Inability to identify recent use: Drugs take about 5-7 days to become detectable in hair.
• Expense: Hair drug tests generally cost more than other testing methods.
• Result variability: Factors such as hair color and individual growth differences can influence drug metabolite concentrations in hair.

Note: Although commonly referred to as "hair follicle tests," the test analyzes 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.
