Hair Follicle Drug Testing - Dellwood, MN

What it is, How it works

Hair analysis is recognized as a potent method for identifying substance use. The hair captures a timeline of drug and alcohol consumption by embedding biomarkers within the strands as they grow. When sampled near the scalp, hair can indicate substance use for a duration of up to 3 months. The ease of collection, resistance to tampering, and simplicity in transportation make hair a favourable option.

A 1.5-inch sample comprising roughly 200 strands (comparable to a #2 pencil in diameter) near the scalp supplies 100mg, which is the optimal amount for both screening and confirmation. For EtG, additional elements, or tests exceeding 10 panels, a sample weighing 150mg is advised. It is suggests using a jeweler's scale for weighing. Should head hair be non-existent, a similar amount of body hair can be used. Referencing head hair implies scalp hair only, whereas body hair encompasses facials, axillary, and other hair types.

Process Overview

The laboratory drug testing process is segmented into four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into a lab's system, ensuring the sample's seal and shipment integrity, assigning a random LAN (Laboratory Accessioning Number), and inputting any additional data absent in an electronic chain of custody.

Screening initiates with a rapid assessment for drug abuse indicators. Although cost-effective for ruling out drug use in most instances, positive Screening outcomes must undergo confirmation to hold in court. Samples flagged as presumptive positives in Screening require further confirmation.

Upon a presumptive positive result at Screening, additional hair is extracted from the initial specimen for Extraction. This phase isolates drugs from hair at significantly lower concentrations in comparison to alternative methods (like urine or oral fluid), rendering hair drug screening the most challenging methodology.

GC/MS, GC/MS/MS, or LC/MS/MS methods are employed in confirming positive screenings. All presumptive positives are cleansed pre-confirmation as necessary. The entire process, from Accessioning through Confirmation, is audited under both CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can identify drug usage up to 90 days, unlike urine tests which offer a shorter timeframe.
• Resistance to manipulation: Cheating a hair drug test is extremely challenging, enhancing result reliability.
• Historical usage insights: Hair testing provides a pattern of drug consumption over time rather than merely recent usage.

Limitations:

• Incapable of detecting recent use: Drugs become traceable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug testing typically incurs higher costs than other testing techniques.
• Result variances: Drug metabolite concentration in hair may fluctuate due to hair color and individual growth variations.

Note: Despite being called "hair follicle tests", these tests analyze the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Comparing hair follicle testing to traditional urine tests reveals significant benefits. Hair testing offers superior detection accuracy and reliability. Unlike urine tests, hair samples provide a longer historical perspective of substance use, capturing drug activity for several months. This makes hair testing a more robust option for screening purposes, as it is less susceptible to short-term abstinence measures.

Extended Detection Window

One of the key advantages of hair follicle testing in Dellwood, MN is the extended detection window.

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.
