Hair Follicle Drug Testing - Blairsburg, IA

What it is, How it works

Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair retains a lengthy record of alcohol and drugs by embedding biomarkers within its fibers as it grows. If taken near the scalp, hair can suggest up to about a 3-month detection duration for alcohol and drugs. Hair is straightforward to collect, relatively hard to tamper with, and simple to transport.

A 1.5-inch section of around 200 hair strands (similar to the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, the ideal sample for analysis and confirmation. For EtG, supplementary tests, and/or tests exceeding 10 panels, 150mg of the hair is advised. It is recommended to measure the hair sample using a jeweler’s scale. If scalp hair is unavailable, an equivalent amount of body hair can be utilized. Mention of head hair pertains to scalp hair exclusively. Body hair encompasses all other types of hair (e.g., facial, axillary).

Process Overview

The primary stages in the laboratory processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary handling of a sample into a laboratory's system. This processes verification of the sample's seal and shipment, assigns an arbitrary LAN (Laboratory Accessioning Number), and completes any extra data entry absent from an electronic chain of custody system.

Screening is a preliminary rapid assessment for drugs. Though Screening economically rules out drug consumption for most samples, a positive outcome requires confirmation for court validity. Any samples with a presumptive positive during Screening necessitate a subsequent confirmation.

If a sample shows presumptive positivity in the Screening phase, additional hair is extracted from the original specimen and prepped for Extraction. In this segment, drugs are extracted from hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), affirming hair drug screening as the most challenging technique to execute.

Confirmation of any positive Screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as necessary. The comprehensive laboratory process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug use up to 90 days, unlike urine tests which have a shorter detection period.
• Hard to deceive: Manipulating a hair drug test is notably difficult, rendering the results more reliable.
• Offers historical insight: It reveals a drug use pattern over time, beyond recent usage.

Limitations:

• Inability to detect recent use: Drugs are noticeable in hair after roughly 5-7 days.
• Expense: Hair drug assessments generally cost more than other drug testing techniques.
• Result Variability: Elements like hair color and personal hair growth differences can affect the concentration of drug metabolites in the hair.

Note: Frequently termed "hair follicle tests", the test actually evaluates the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Blairsburg, IA, hair follicle testing stands out as superior to traditional urine tests for several reasons. Accuracy and longer detection periods give hair testing an edge.

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. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
