Hair Follicle Drug Testing - Lohrville, IA

What it is, How it works

Hair analysis has emerged as an effective technique for identifying drug and alcohol consumption. Hair retains a long-term record of alcohol and drug use by embedding biomarkers within the strands of growing hair. Hair collected close to the scalp can provide a detection period of up to three months for alcohol and drugs. The collection of hair is straightforward, hard to tamper with, and simple to transport.

A 1.5-inch portion consisting of around 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp supplies 100mg, which is the optimal amount for both screening and validation. In the case of EtG, add-ons, and tests exceeding 10 panels, a 150mg sample is advised. Utilizing a jeweler’s scale to weigh the specimen is suggested. If scalp hair cannot be gathered, an equivalent quantity of body hair can be utilized. When scalp hair is mentioned, it is specific to head hair. Body hair includes any other types of hair (facial, axillary, etc.).

Process Overview

The primary stages in laboratory processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

The stage of Accessioning deals with the primary processing of a sample into a lab’s system, ensuring proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry not covered by an electronic chain of custody system.

Screening involves an initial rapid analysis for drugs of abuse. Although Screening can efficiently rule out drug use for most samples, if the screen is positive, it must be confirmed for legal admissibility. All samples found presumptively positive in Screening require a confirmation step.

Should a sample be presumptively positive in the Screening stage, additional hair is extracted from the original specimen for the Extraction phase. At this stage, much lower concentrations of drugs are extracted from hair than other techniques (e.g., urine or oral fluid), contributing to the complexity of hair drug screening.

Confirmation for any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation as necessary. The complete lab process, from Accessioning through Confirmation, is examined under both the CAP (College of American Pathologists) Hair guidelines and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection period: Hair tests can identify drug usage for up to 90 days, unlike urine tests which offer a shorter detection period.
• High accuracy: Cheating a hair drug test is notably hard, enhancing result accuracy.
• Provides usage patterns: It can display a trend of drug use over time, not merely recent use.

Limitations:

• Cannot detect recent use: Drugs take about 5-7 days post-use to become detectable in hair.
• Expense: Hair drug tests are typically costlier compared to other drug testing approaches.
• Result variability: Aspects like hair color and personal variations in hair growth can influence drug metabolite concentrations in hair.

Note: Though often called "hair follicle tests," the actual test evaluates the hair strand, excluding the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why choose hair follicle testing over traditional urine tests in Lohrville, IA? The benefits are clear: superior detection accuracy and reliability. Hair testing offers a longer detection window and is less prone to tampering. Where urine tests might miss recent drug use, hair tests provide a comprehensive view of drug and alcohol usage frequency, ensuring businesses maintain their drug-free policies effectively.

Extended Detection Window

In Lohrville, IA, hair follicle testing provides an extended detection window, capable of revealing substance use over a remarkable 90-day span. This long-term detection capability delivers employers a complete and historical substance profile, helping in evaluating the patterns and behavior associated with drug and alcohol use. It's an insightful tool for making informed decisions in hiring or ongoing employee assessment.

Tamper-Resistant Testing Method

Hair follicle tests in Lohrville, IA provide a tamper-resistant method for drug testing. Unlike urine tests, hair samples are difficult to adulterate, and the collection process is less intrusive, reducing the potential for manipulation. This ensures the integrity and reliability of the results, giving stakeholders the assurance of an unquestionable drug testing outcome.

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.
