Hair Follicle Drug Testing - Portland, IA

What it is, How it works

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extended history of substance use by embedding biomarkers within the fibers of the growing strand. When cut near to the scalp, hair can reveal alcohol and drug usage for up to a 3-month period. It is easy to gather, relatively resistant to tampering, and straightforward to send.

A 1.5-inch section with around 200 hair strands (similar in size to a #2 pencil) closest to the scalp yields 100mg of hair, the preferred amount for testing and verification. For EtG, additional tests, and/or panels exceeding 10, 150mg is suggested. We advise measuring the sample on a jeweler's balance. If scalp hair is unavailable, a similar quantity of body hair can be used. When mentioning head hair, it specifically means scalp hair. Body hair encompasses all other forms (facial, axillary, etc.).

Process Overview

The four core steps in laboratory processing of a drug test involve Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the entry of a sample into the lab's system. This process includes ensuring the sample’s seal and proper shipping, assigning a random LAN (Laboratory Accessioning Number), and finalizing any additional data entry missing from an electronic chain of custody.

Screening consists of a preliminary assessment for substance misuse. This step efficiently rules out drug use in most samples, but any positive result requires verification to be court-acceptable. Samples that show preliminary positive results in Screening require further confirmation.

If the Screening stage yields a presumptive positive, additional hair is extracted from the original sample and prepared for Extraction. During this process, drugs are isolated from hair at much lower concentrations compared to other techniques (e.g., urine or oral fluid), highlighting why hair drug testing is the most complex procedure to execute.

Confirmation for any positive screening is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation as necessary. The whole laboratory journey from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and certified to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair tests uncover drug use up to 90 days, whereas urine tests have a more limited window.
• Hard to manipulate: Cheating on a hair drug test is highly challenging, enhancing result accuracy.
• Supplies historical insight: It shows a trend of drug usage across a timeframe, not just recent activity.

Limitations:

• Recent use detection is not possible: After 5-7 days, drugs become detectable in hair.
• Expense: Hair tests are typically pricier than other drug testing techniques.
• Result variability: Hair color, along with personal hair growth differences, can influence metabolite concentration in hair strands.

Note: Commonly referred to as "hair follicle tests," the actual examination focuses on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing with more traditional urine tests in Portland, IA, the superior accuracy of hair testing becomes evident. Hair tests offer a longer detection window, making it a more reliable option for employers seeking thorough screening. Urine tests fall short in detecting long-term substance use, where hair testing excels with accuracy and dependability.

Extended Detection Window

In Portland, IA, hair follicle testing is noted for its extended detection window, spanning up to 90 days. This provides employers with a detailed overview of an individual's drug history, offering a more comprehensive look at their substance use over an extended period. This capability is unmatched when compared to other testing methods.

Tamper-Resistant Testing Method

Hair follicle testing significantly minimizes sample adulteration concerns in Portland, IA. The tamper-resistant nature ensures that test results are unquestionable and reliable. This method curtails the potential for manipulation, providing peace of mind to those relying on accurate drug testing outcomes.

Convenient Nationwide Locations

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.
