Hair Follicle Drug Testing - Treynor, IA

What it is, How it works

Hair analysis is gaining recognition as a robust means for uncovering drug and alcohol consumption. Hair captures enduring evidence of alcohol and various drugs by embedding biomarkers within the fibers as the hair grows. Sampling hair near the scalp can reveal a detection span of up to three months for alcohol and other drugs. Hair is straightforward to gather, relatively tamper-proof, and convenient to transport.

A 1.5-inch portion consisting of around 200 hairs (roughly equal to a #2 pencil's diameter) closest to the scalp provides 100mg, which is the preferred sample for both screening and verification. For EtG, additional parameters, and/or assessments exceeding 10 panels, a 150mg sample is suggested. We advise using a jeweler’s scale to measure the specimen. If scalp hair is missing, a similar quantity of body hair may be used. When mentioning head hair, we specifically refer to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The four key stages in processing a drug test result in a laboratory include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary processing of a sample into the laboratory's system. This entails confirming the specimen was properly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data input not covered by an electronic chain of custody system.

Screening involves a preliminary brisk evaluation for identifying drugs of abuse. Even though Screening is a cost-efficient method to disprove drug use for most samples, any positive screening requires confirmation to be valid in legal settings. Samples showing tentative positive results in Screening necessitate a thorough confirmation.

When a sample shows tentative positivity in Screening, additional hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are isolated from hair at significantly lower concentrations compared to other methods (such as urine or saliva), which is why hair drug screening is considered the most intricate methodology.

Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with tentative positive results are thoroughly cleaned before confirmation as necessary. The complete laboratory workflow from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the accreditation conforming to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use up to 90 days, compared to urine tests that offer a shorter detection span.
• Challenging to manipulate: Cheating hair drug tests is notably difficult, ensuring more precise results.
• Reveals historical patterns: Offers insights into drug usage patterns over time rather than just recent usage.

Limitations:

• Incapable of detecting recent use: Roughly 5-7 days are required for drugs to become detectable in hair.
• Expense: Hair drug tests are typically pricier relative to other drug testing methodologies.
• Result variability: Aspects like hair color and personal differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Commonly referred to as "hair follicle tests", the evaluation targets the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Treynor, IA is evident when comparing the two methods. Hair testing offers enhanced detection accuracy and reliability, making it superior. Unlike traditional urine tests, hair testing provides a longer detection window, uncovering substance use that might be missed by traditional methods. This leads to a more comprehensive understanding of an individual's substance history.

Extended Detection Window

Extended Detection Window is a key advantage of hair follicle testing in Treynor, IA. While urine tests provide a short-term view, hair tests offer a detection period of up to 90 days. This allows employers to gain a more extensive understanding of an applicant's or employee's substance use history, crucial for maintaining a safe and compliant workplace environment.

Tamper-Resistant Testing Method

Tamper-Resistant Testing Method underscores the secure nature of hair follicle tests in Treynor, IA. These tests reduce the risk of sample manipulation, offering results that are both reliable and difficult to question. This method's integrity ensures that organizations can trust their findings, fostering a secure and drug-free environment.

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.
