Hair Follicle Drug Testing - Annette, AK

What it is, How it works

Hair analysis has emerged as a potent method for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drugs by encapsulating biomarkers within the strands as they grow. When clipped near the scalp, hair can offer approximately a 3-month detection span for substances. Hair collection is straightforward, somewhat resistant to tampering, and convenient to transport.

A segment measuring 1.5 inches of roughly 200 strands of hair (similar in size to a #2 pencil) closest to the scalp yields 100mg, the optimal amount for screening and validation. For EtG, supplementary tests, and/or panels exceeding 10, collecting 150mg of hair is advised. Employing a jeweler’s scale for weighing the sample is recommended. In the absence of scalp hair, an equivalent quantity of body hair can be taken. Head hair refers exclusively to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The four primary stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase of integrating a sample into a lab's system. It involves ensuring the sample was properly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and completing any further data entry not facilitated by an electronic chain of custody.

Screening entails a preliminary rapid test for drugs of abuse. While Screening is a budget-friendly approach to dismiss drug usage in most samples, a positive result demands confirmation to be permissible in legal proceedings. Presumptive positives in Screening necessitate additional confirmation.

Should a sample be presumptively positive during Screening, more hair is drawn from the original sample for Extraction. Here, drugs are isolated from hair at significantly lower concentrations than with other methods (e.g., urine or oral fluid), accounting for the complexity of hair drug analysis.

Confirmation of any presumptive positive screen is executed through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing before confirmation as required. The entire lab procedure from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, as opposed to urine tests which have a briefer detection period.
• Difficult to manipulate: Cheating a hair drug test is highly challenging, increasing the reliability of the results.
• Provides usage history: Offers a pattern of drug use over time, not just recent consumption.

Limitations:

• Limitations in detecting recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug tests are typically costlier than other drug testing methods.
• Result variability: Hair color and individual growth differences can influence drug metabolite levels in hair.

Note: Despite commonly being called "hair follicle tests", the analysis evaluates the hair strand rather than the follicle itself beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

Hair follicle tests offer numerous advantages over urine tests in Annette, AK. They deliver superior detection accuracy and reliability, which is vital for employers with strict drug policies. While urine tests detect recent drug use, hair follicle tests provide a broader timeframe for spotting substance abuse, aligning with zero-tolerance policies and offering a robust alternative.

Extended Detection Window

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.
