Hair Follicle Drug Testing - Belknap, IA

What it is, How it works

Hair tests have emerged as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged record of substance use by embedding biomarkers in the strands during growth. When gathered close to the scalp, hair can reveal drug and alcohol use up to around a 3-month period. Hair collection is straightforward, relatively resistant to tampering, and simple to transport.

A 1.5-inch length comprising approximately 200 hair strands (similar in size to a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal quantity for both screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, 150mg of the sample is advised. We suggest weighing the sample using a jeweler's scale. If scalp hair is not available, a comparable amount of body hair can be utilized. When we mention head hair, we mean only scalp hair. Body hair pertains to all other hair forms (facial, axillary, etc.).

Process Overview

The laboratory analysis of a drug test result comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.

Within Accessioning, a sample is initially integrated into the laboratory's system. This stage includes ensuring the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and performing any extra data entry not covered by an electronic chain of custody system.

Screening is a preliminary quick evaluation for substance misuse. While Screening is a cost-efficient technique for excluding drug use for most samples, a positive screen requires confirmation to be court-admissible. Any Screening samples that show presumptive positivity require further confirmation.

Should a sample be presumptively positive during Screening, additional hair is drawn from the original sample and prepped for Extraction. Here, drugs are extracted from hair at much lower concentrations compared to other methods (e.g., urine or oral fluids), which makes hair drug screening the most challenging to execute.

Confirmation of any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples at this stage are washed appropriately for confirmation. The complete laboratory procedure from Accessioning to Confirmation is examined following both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can disclose drug use up to 90 days back, whereas urine tests possess a shorter detection timeframe.
• High difficulty to evade: Hair drug tests are very hard to falsify, thus yielding more reliable results.
• Displays historical patterns: It reveals a timeline of drug consumption, not just recent usage.

Limitations:

• Inability to identify recent use: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug tests tend to be pricier than alternative drug testing techniques.
• Result variability: Factors such as hair color and personal differences in hair growth can influence drug metabolite concentration in hair.

Note: Despite the common term "hair follicle tests", the test actually examines the hair strand, not the follicle under the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Belknap, IA, hair follicle testing surpasses traditional urine tests by providing superior detection accuracy.

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.
