Hair Follicle Drug Testing - Blocher, IN

What it is, How it works

Hair analysis is now recognized as an effective method for identifying drug and alcohol consumption. Hair can offer an extensive history of alcohol and drug use by capturing biomarkers within the fibers of the developing hair strand. When hair is gathered near the scalp, it can present nearly a 3-month detection timeframe for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and simple to transport.

An ideal hair sample should consist of about 200 strands (the approximate width of a #2 pencil) measuring 1.5 inches from the scalp, yielding 100mg for effective screening and confirmation. For EtG, additional tests, or panels beyond ten, a 150mg sample is advisable. Utilizing a jeweler’s scale to weigh the specimen is suggested. If no scalp hair is present, a comparable quantity of body hair can be used. References to head hair pertain only to scalp hair, whereas body hair includes all other types (facial, axillary, etc.).

Process Overview

The primary phases in lab processing of a drug testing result consist of Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the sample's initiation into the lab's system, with tasks like verifying proper sealing and shipping of the sample, assigning a LAN (Laboratory Accessioning Number), and completing any missing data entry not captured by an electronic chain of custody.

Screening acts as a preliminary check for drug presence. While it's an economical option for ruling out drug use in most cases, a positive screen must be substantiated for legal acceptance. Any sample presumed positive in Screening proceeds to secondary confirmation.

Should a sample point to positive status in the Screening phase, additional hair is extracted and prepped for the Extraction phase. Drugs are isolated from hair at lower concentrations than with alternative methods (e.g., urine or oral fluid), underscoring why hair drug testing is particularly challenging.

Verification of any positive Screening results is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Pre-confirmation, all presumptive positive samples undergo washing as required. The full lab process, spanning Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection range: Hair drug assessments reveal drug usage up to 90 days, unlike urine tests with a brief detection span.
• Hard to deceive: Cheating on hair drug tests is complex, ensuring high accuracy.
• Shows usage patterns: It provides insights into drug use trends over time, beyond just recent usage.

Limitations:

• Unable to detect recent intake: Drugs typically need 5-7 days to become traceable in hair.
• Expense: Hair drug tests are usually pricier compared to other drug testing techniques.
• Result variability: Factors like hair color and individual growth differences can influence drug metabolite levels in hair.

Note: While commonly termed as "hair follicle tests", the analysis targets the hair strand beyond the scalp-rooted follicle.

Why Hair Follicle Testing Beats Urine Testing

Why is hair follicle testing superior to urine testing in Blocher, IN? Hair tests provide a more reliable detection rate and greater accuracy. Where urine tests have a narrower detection timeframe, hair tests reveal a broader history of substance use, unaffected by short-term abstinence, providing thorough historical insight.

Extended Detection Window

One of the defining advantages of hair follicle testing in Blocher, IN, is its extended detection window. It allows for the identification of drug use over a span of up to 90 days. This extended period offers employers a clear and comprehensive understanding of an individual's substance use history.

Tamper-Resistant Testing Method

Hair follicle testing is notably tamper-resistant, particularly advantageous in Blocher, IN. It mitigates the risks of sample adulteration, thereby ensuring results are both reliable and beyond contestation. This security makes such tests a preferred choice for many organizations and legal bodies.

Convenient Nationwide Locations

With convenient locations nationwide, testing via hair follicle tests in Blocher, IN, is streamlined and accessible. Our network of centers ensures that testing services are quick, hassle-free, and nearby, catering to the needs of individuals and organizations alike.

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.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix.
