Hair Follicle Drug Testing - Newkirk, NM

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair strands capture biomarkers within the fibers, offering a long-standing record of substance usage. A sample gathered close to the scalp can reveal drug or alcohol presence up to a three-month period. It's straightforward to collect, hard to tamper with, and convenient to transport.

A 1.5-inch portion comprising roughly 200 hair strands, akin to the width of a #2 pencil, close to the scalp provides 100mg—a perfect sample for screening and confirmation. For scenarios requiring EtG add-ons or panels beyond 10, a recommendation for a 150mg specimen is given. Using a jeweler’s scale for weight measurement is advised. Should scalp hair not be accessible, equivalent body hair may be used instead. When referring to head hair, the focus is on scalp hair specifically, while body hair includes all other forms (such as facial and axillary).

Process Overview

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

During Accessioning, the sample is initially processed into the laboratory's procedure. The process ensures correct sealing and shipment of the sample, assigns a unique LAN (Laboratory Accessioning Number), and completes any necessary additional data recording absent from an electronic chain of custody system.

Screening performs an initial rapid assessment for substance abuse. It's cost-efficient and eliminates drug use in most samples, but any positive findings need confirmation to be valid in legal scenarios. Presumptively positive samples from Screening require further confirmation processes.

If Screening suggests a sample is positive, additional hair is extracted from the original specimen for the Extraction phase. Here, substances are extracted from hair in much lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug pre-extraction the most challenging approach.

Confirmation for any positive result uses techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All preliminary positive samples undergo wash processes before confirmation if required. The entire lab sequence from Accessioning to Confirmation undergoes scrutiny under both the CAP Hair designation and ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection span: Detects drug use over a 90-day period, outlasting urine tests which have shorter detection spans.
• Resistance to tampering: Hair tests are substantially safeguarded against tampering, yielding more dependable results.
• Offers comprehensive data: Affords an overview of drug use over time, not solely focusing on recent usage.

Limitations:

• Inability to detect recent use: Drugs become traceable in hair after approximately 5-7 days.
• Expense: Hair drug testing tends to be more costly than alternative testing procedures.
• Result variability: Elements like hair color and personal hair growth variations influence drug metabolite concentrations in hair.

Note: Despite being called "hair follicle tests", the procedure analyzes the hair strand, excluding the scalp's hair follicle.

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.
