Hair Follicle Drug Testing - Hurt, VA

What it is, How it works

Hair analysis has emerged as an effective resource for detecting drug and alcohol consumption. Hair offers a lengthy historical record by embedding biomarkers within the fibers as the strand develops. When acquired near the scalp, hair can reveal alcohol and drug presence for up to roughly 90 days. Hair collection is straightforward, fairly hard to tamper with, and convenient for shipping.

A sample measuring 1.5 inches, consisting of around 200 hair strands (about the width of a #2 pencil) near the scalp yields 100mg of hair, which is the preferred amount for both screening and confirmation. For EtG, additional tests, and/or for analyses exceeding 10 panels, 150mg of the sample is advisable. Using a jeweler's scale for weighing the hair collection is suggested. In the absence of scalp hair, an equivalent quantity of body hair can be gathered. When we mention head hair, it pertains solely to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Overview of the Process

There are four fundamental steps in the lab's progression of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial integration of the specimen into the lab's system. This procedure ensures the sample's intact shipping, assigns an arbitrary LAN (Laboratory Accessioning Number), and completes any extra data input absent from an electronic chain of custody framework.

Screening is a preliminary rapid assessment for substance misuse. Despite being a cost-efficient means to dismiss drug use in most specimens, a positive screen necessitates verification to hold up in legal contexts. Every sample flagged as presumptively positive in Screening requires a follow-up confirmation.

Should a sample show presumptive positivity in the Screening phase, further hair is taken from the original specimen to prepare for Extraction. In this process, substances are drawn out of the hair at a considerably reduced concentration in comparison to other techniques (e.g., urine or saliva), making hair drug screening the most challenging method to execute.

Any positive indications in the Screening are validated via GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptively positive are cleansed before confirmation as necessary. The complete lab procedure from Accessioning to Confirmation undergoes evaluation under the CAP (College of American Pathologists) Hair categorization and the ISO / IEC 17025 accreditation standards.

Pros of using hair drug tests:

• Extensive detection range: Unlike urine tests, hair drug tests can uncover drug use for up to 90 days.
• Fraudulence resistant: The difficulty in deceiving hair drug tests enhances the accuracy of the results.
• Tracks historical consumption: It can outline a trajectory of substance use over time, rather than merely recent usage.

Drawbacks:

• Unable to detect immediate use: A period of around 5-7 days is required for drugs to be evident in hair.
• Expense: Hair drug testing typically incurs higher costs compared to alternative methods.
• Result variance: Attributes, including hair color and personal hair growth differences, can influence the concentration of drug metabolites in hair.

Note: Commonly termed “hair follicle tests,” these actually examine the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Surpasses Urine Tests in Hurt, VA lies in its unparalleled reliability. Unlike urine tests, hair follicle analysis spans a longer detection period and offers a higher degree of accuracy. This ensures a more dependable assessment of substance use, making it a favored choice for those seeking comprehensive drug testing results.

Extended Detection Window

The Extended Detection Window offered by hair follicle tests in Hurt, VA, is a significant advantage. Unlike urine tests, which detect recent use, hair follicles can reveal drug use histories up to 90 days. This extended period allows employers to gain a deeper understanding of an individual's substance use habits over time.

Tamper-Resistant Testing Method

In Hurt, VA, hair follicle testing stands out as a Tamper-Resistant Testing Method. This testing method greatly reduces the risk of sample adulteration, providing results that are both credible and question-free. Its difficulty to manipulate ensures the integrity of the test, maintaining trust in its outcomes.

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.
