Hair Follicle Drug Testing - Lowes Island, VA

What it is, How it works

Hair testing has emerged as an effective instrument in detecting drug and alcohol consumption. Hair preserves a prolonged record of alcohol and drugs by embedding biomarkers within the fibers as the hair grows. When clipped near the scalp, hair can offer up to nearly a 3-month detection timeframe for alcohol and drugs. Hair is effortless to gather, moderately resistant to tampering, and simple to send.

A 1.5-inch section comprising roughly 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal sample for screening and verification. For EtG, add-ons, and/or assessments exceeding 10 panels, 150mg of the sample is advised. We advocate weighing the sample on a jeweler’s scale. If scalp hair is inaccessible, an equivalent amount of body hair can be collected. In the context of head hair, we are specifically discussing scalp hair. Body hair pertains to all other varieties of hair (facial, axillary, etc.).

Process Overview

The principal phases involved in the laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the preliminary handling of a sample into a lab’s system. This includes confirming that the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not furnished by an electronic chain of custody system.

Screening involves an initial rapid assessment for drug abuse. Although Screening is an economical approach to dismiss drug usage in most samples, a positive screen requires confirmation to be permissible in court. Any samples presumptively positive in Screening necessitate secondary confirmation.

If a sample is presumptively positive during the Screening phase, additional hair is extracted from the initial sample and primed for Extraction. Here, drugs are extracted from hair at significantly lower concentrations than in other methodologies (e.g., urine or oral fluid), indicating why hair drug screening is the most challenging methodology to undertake.

Confirmation of any positive screening result is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation if needed. The comprehensive laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, in contrast to urine tests which have a shorter detection period.
• Difficult to deceive: A hair drug test is incredibly challenging to manipulate, ensuring more reliable results.
• Offers historical information: It reveals a pattern of drug use over time, not just recent consumption.

Limitations:

• Inability to detect recent use: It requires approximately 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests typically cost more than alternative drug testing methods.
• Result discrepancies: Elements such as hair color and individual hair growth rates can influence the concentration of drug metabolites in the hair.

Note: Though often called "hair follicle tests", the actual test analyzes the hair strand and not the hair follicle beneath the scalp

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.
