Hair Follicle Drug Testing - Dillingham, AK

What it is, How it works

Hair analysis has become recognized as an effective method for detecting alcohol and drug consumption. Hair captures a detailed timeline of substances by embedding biomarkers within the strand’s follicles. When gathered near the scalp, hair can reveal a usage history spanning up to a 3-month period for alcohol and drugs. It is straightforward to collect, relatively challenging to tamper with, and convenient to transport.

Approximately 1.5 inches of hair comprising roughly 200 strands, akin to a #2 pencil's thickness, from near the scalp will yield about 100mg of hair, the optimal quantity for analysis and verification. For EtG, additional screenings, and/or tests exceeding 10 panels, a sample of 150mg is suggested. It's advisable to measure the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent volume of body hair may be utilized. "Head hair" pertains solely to scalp hair. "Body hair" includes all other types (facial, axillary, etc.).

Process Overview

The essential phases in processing a drug test in the lab comprise Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary integration of a sample into a lab's database. Tasks here include verifying proper sample sealing and shipping, generating a unique LAN (Laboratory Accessioning Number), and executing any requisite data entry absent from an electronic custody framework.

Screening is a preliminary procedure to identify substances of abuse. Although Screening effectively excludes drug presence in most specimens, further validation is necessary for legal admissibility when a screen returns positive. Samples yielding a presumptive positive in Screening must undergo subsequent confirmation.

In cases of presumptive positivity during Screening, additional hair is extracted from the primary sample and processed for Extraction. This process retrieves drugs from hair at significantly reduced levels compared to alternate methods (e.g., urine or saliva), rendering hair drug testing particularly complex.

Confirming any positive results from Screening is achieved through GC/MS, GC/MS/MS or LC/MS/MS techniques. All samples with presumptive positivity undergo washing before confirmation as warranted. From Accessioning to Confirmation, all procedures are scrutinized under CAP (College of American Pathologists) Hair classification and comply with ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair tests can trace drug usage for up to 90 days versus the limited window offered by urine tests.
• Difficulty to cheat: Hair tests are challenging to falsify, increasing the result's dependability.
• Provides historical data: It outlines drug use trends over time, beyond mere recent activity.

Limitations:

• Cannot detect recent use: Detection in hair takes about 5-7 days post consumption.
• Cost: Hair testing usually incurs higher expenses than alternative methodologies.
• Variations in results: Variables like hair pigmentation and individual growth rates may influence drug metabolite concentrations in hair.

Note: Frequently termed "hair follicle tests", these evaluations examine the hair strand, not the scalp’s hair follicle.

Why Hair Follicle Testing Beats Urine Testing

Why choose hair follicle testing over urine testing in Dillingham, AK? Hair tests offer greater detection periods and accuracy. They uncover substance use over a 90-day window, compared to urine tests' limited reach, providing employers with clearer insights into an individual's history.

Extended Detection Window

One of the primary advantages of hair follicle testing in Dillingham, AK, is the extended detection window. Unlike conventional tests, hair analysis reveals substance use up to 90 days prior.

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.
