Hair Follicle Drug Testing - Asbury, IA

What it is, How it works

Hair analyses have become recognized as an effective method for identifying drug and alcohol consumption. Hair strands offer a detailed timeline of alcohol and drug intake by encapsulating biomarkers within the hair's fibers. When samples are taken near the scalp, they can disclose up to a three-month detection span for various substances. The collection process for hair is straightforward, challenging to tamper with, and easy to send.

A hair sample measuring 1.5 inches and comprising approximately 200 strands (analogous in size to a #2 pencil) from the scalp delivers 100mg of hair, which is optimal for assessments and verifications. For EtG add-ons and/or evaluations exceeding 10 panels, a 150mg specimen is advised. Using a jeweler's scale for specimen measurement is recommended. If scalp hair is absent, an equivalent amount of body hair is an alternative. "Head hair" specifically denotes scalp hair, whereas "body hair" includes all other types (facial, axillary, etc.).

Process Overview

The laboratory workflow for processing a drug test consists of four key stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is introduced into the laboratory's system, including verifying its seal and proper shipment, assigning a Laboratory Accessioning Number (LAN), and completing any extra data entry absent from an electronic custody chain.

Screening is a preliminary assessment for drug abuse. This affordable procedure effectively negates drug use in most samples, yet any positive outcome requires confirmation for legal validity. Any samples that result in presumptive positives in Screening necessitate further confirmation.

In cases where Screening suggests a positive, additional hair is extracted from the initial collection for further Extraction. During this phase, substances are extracted from hair in significantly lower concentrations than with other methods (e.g., urine or oral fluid), making hair drug testing particularly challenging.

The Confirmation of a positive Screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples receive a mandatory wash before confirmation. The entire lab procedure, from Accessioning to Confirmation, undergoes scrutiny under both CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal substance use for up to 90 days, unlike urine tests, which have a shorter detection window.
• Low likelihood of deception: Cheating a hair drug test is highly challenging, resulting in more reliable outcomes.
• Historical usage data: Provides patterns of drug use over time, rather than just recent use.

Limitations:

• Inability to detect recent usage: Drugs take about 5-7 days to become traceable in hair.
• Expense: Hair drug tests generally cost more than other methods of drug testing.
• Result variability: Elements like hair color and individual growth differences can influence metabolite concentrations in hair.

Note: While commonly termed "hair follicle tests," the test examines the hair strand itself, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Asbury, IA, hair follicle testing is often considered superior to traditional urine tests due to its enhanced detection accuracy and reliability. While urine tests can only detect recent drug use, hair testing captures a broader spectrum, providing a more comprehensive picture of substance history. The meticulous nature of hair testing ensures that results are dependable and less prone to inaccuracies commonly found in urine analyses.

Extended Detection Window

The extended detection window is a key advantage of hair follicle testing, especially in Asbury, IA. Unlike other methods, it can identify drug use over a significantly longer timeline, up to 90 days. This feature offers employers in-depth insight into the ongoing and past substance use habits of employees or candidates, making it a preferred choice for pre-employment screenings and routine checks.

Tamper-Resistant Testing Method

Hair follicle testing in Asbury, IA, offers a robust solution against sample tampering. Unlike urine tests, which can sometimes be adulterated or manipulated, hair tests provide results that are difficult to alter. The integrity of the sample is maintained from collection to analysis, ensuring that the findings are dependable and trustworthy, giving employers and authorities confidence in the test outcomes.

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.
