Hair Follicle Drug Testing - Middleburg, KY

What it is, How it works

Hair testing has gained recognition as an effective means for detecting drug and alcohol consumption. It offers a comprehensive historical record of alcohol and drugs by capturing biomarkers in the hair strand's fibers as it grows. A sample collected near the scalp can provide a detection window of up to roughly three months for alcohol and drugs. Hair samples are straightforward to obtain, challenging to tamper with, and convenient to transport.

A hair sample measuring 1.5 inches in length and consisting of about 200 strands (approximately the diameter of a #2 pencil) nearest the scalp yields 100mg of hair, which is ideal for test screening and verification. For EtG, supplemental tests, and/or tests exceeding 10 panels, a sample of 150mg is suggested. We advocate for the use of a jeweler’s scale to measure the sample weight accurately. If scalp hair is non-existent, an equivalent portion of body hair can be used. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

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

Accessioning denotes the initial sample processing into a laboratory's system. It involves verifying proper sealing and shipment of the sample, generating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent in an electronic chain of custody system.

Screening includes a preliminary rapid assessment for drugs of abuse. Although Screening serves as a cost-effective method to exclude drug usage in most samples, a positive screen necessitates confirmation to hold up in legal settings. Any samples deemed presumptively positive during Screening do require a subsequent confirmation.

For samples with a presumptively positive result in the Screening phase, additional hair is extracted from the initial sample and prepped for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations than those in methods like urine or oral fluid, which is why hair drug screening is among the most complex methodologies.

The Confirmation of any positive Screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptively positive samples undergo washing before Confirmation if necessary. The complete laboratory procedure, from Accessioning to Confirmation, undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Protracted detection span: Hair drug tests offer a detection period of up to 90 days, surpassing the shorter detection window of urine tests.
• Challenging to falsify: Hair drug tests are resilient to cheating, enhancing result accuracy.
• Delivers historical insights: It reveals a pattern of drug consumption over time, not just recent usage.

Limitations:

• Inability to detect recent use: Drugs take roughly 5-7 days to register in hair.
• Expense: Hair drug tests typically incur higher costs compared to alternative testing methods.
• Variability in results: Elements such as hair color and individual differences in hair growth can impact the drug metabolite concentration in hair.

Note: Although frequently dubbed "hair follicle tests", the analysis targets the hair strand, not 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.
