Hair Follicle Drug Testing - Littleport, IA

What it is, How it works

Hair analysis is increasingly regarded as an effective method for identifying drug and alcohol consumption. Hair offers an extended timeline of substance use by embedding biomarkers within the strands as they grow. When obtained near the scalp, hair can provide detection capability for alcohol and other substances for up to three months. It is easy to collect, challenging to tamper with, and convenient for shipping.

A 1.5-inch segment of approximately 200 hair strands (equivalent to a #2 pencil) nearest the scalp provides 100mg of hair, the preferred amount for screening and validation. For EtG tests, add-ons, or tests exceeding 10 panels, a 150mg sample is advisable. It's recommended to weigh the sample on a jeweler’s scale. If scalp hair is unobtainable, a similar quantity of body hair can be collected. When referring to head hair, it specifically means scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning is the initial step where a sample is integrated into a laboratory’s system. This step involves ensuring the sample was correctly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody system.

Screening is a preliminary check for drugs of abuse. While it is a cost-effective method to eliminate drug use in most samples, a positive screen needs confirmation to be court-admissible. Samples that test presumptively positive in Screening require additional confirmation.

If Screening indicates a presumptive positive, extra hair is extracted from the original sample and readied for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening a challenging methodology.

Any positive result from screening is confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive are washed before confirmation when necessary. The entire laboratory process from Accessioning to Confirmation is conducted under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests have a shorter detection period.
• Hard to tamper with: Cheating a hair drug test is very difficult, which enhances accuracy.
• Captures historical data: It provides a usage pattern over time, beyond just recent use.

Limitations:

• Inability to detect recent use: It takes around 5-7 days for drugs to appear in hair.
• Expense: Generally, hair drug tests are pricier than other drug testing techniques.
• Result variability: Aspects like hair color and individual differences in hair growth can impact drug metabolite concentration in hair.

Note: Often called "hair follicle tests," the analysis evaluates the hair strand rather than the follicle underneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

The preference for hair follicle testing in Littleport, IA is growing due to its superior accuracy over urine tests. While traditional urine assessments detect recent drug use, hair testing offers an extensive insight into substance consumption.

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.
