Hair Follicle Drug Testing - Low Moor, IA

What it is, How it works

Hair testing is now recognized as an effective means for identifying drug and alcohol consumption. Hair captures evidence of drug use over an extended period by embedding biomarkers within the hair fibers as they grow. When sampled close to the scalp, hair offers a detection time frame of up to approximately three months for both alcohol and drugs. Hair collection is straightforward, quite resistant to tampering, and easily transportable.

A 1.5-inch chunk of roughly 200 hair strands (comparable to the girth of a #2 pencil) near the scalp yields 100mg of hair, which is optimal for both screening and verification. For EtG, supplementary analyses, or tests beyond 10 panels, 150mg of hair is suggested. It's advisable to measure the sample with a jeweler's scale. If scalp hair isn’t an option, a comparable quantity of body hair can be taken. Head hair refers exclusively to scalp hair, whereas body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The primary phases in the lab handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial incorporation of a sample into a lab’s database. This step confirms proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data not captured by an electronic chain of custody system.

Screening involves a swift initial drug abuse test. While Screening is a cost-saving measure to dismiss drug presence in most samples, any positive results must be affirmed to hold up in court. Samples showing presumptive positivity in Screening necessitate further confirmation.

If a sample shows presumptive positivity during Screening, additional hair from the primary sample is gathered for Extraction. During Extraction, drugs are mined from hair in far less concentration than in other practices (ex. urine or oral fluid), which is why hair drug screening is the most challenging technique to carry out.

Confirmation of any positive screening outcomes is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo washing as needed. The complete lab procedure from Accessioning to Confirmation is scrutinized per the CAP (College of American Pathologists) Hair guidelines and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests are capable of identifying drug use up to 90 days, whereas urine tests have a shorter detection duration.
• Hard to manipulate: Cheating a hair drug test is exceedingly challenging, thereby ensuring more reliable results.
• Offers historical insight: It provides a timeline of drug use over a duration, not just recent consumption.

Limitations:

• Incapable of spotting recent intake: Drugs don't become detectable in hair until about 5-7 days post-consumption.
• Expense: Hair drug tests generally incur higher costs than other testing methodologies.
• Result variability: Aspects like hair color and individual hair growth discrepancies can alter the concentration of drug metabolites in the hair.

Note: Frequently termed as "hair follicle tests", the evaluation actually focuses on the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing to traditional urine tests in Low Moor, IA, the benefits become clear. Hair testing provides superior detection accuracy and reliability, primarily due to its extended detection window, which can reveal drug use over a longer period. This makes it a preferred method for gaining a comprehensive understanding of substance use.

Extended Detection Window

The extended detection window of hair follicle testing in Low Moor, IA, makes it an invaluable tool for employers. With the ability to detect drug use for up to 90 days, this testing method gives a detailed overview of an individual's substance use history, assisting in making informed hiring and retention decisions.

Tamper-Resistant Testing Method

One of the key advantages of hair follicle testing in Low Moor, IA, is its tamper-resistant nature. Unlike other testing methods, manipulating or adulterating a hair sample is significantly more challenging, ensuring that the results are both reliable and credible, providing assurance to those who rely on them.

Convenient Nationwide Locations

Accessible nationwide and with local locations in Low Moor, IA, drug testing services are both convenient and hassle-free. This network of testing centers ensures that obtaining a test is quick and straightforward, allowing for efficient testing processes that minimize disruption to daily schedules.

Simple, Confidential Process

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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
