Hair Follicle Drug Testing - Oak Hill, FL

What it is, How it works

Recognized as an effective means for detecting drug and alcohol consumption, hair testing captures a lengthy history of substance use by embedding biomarkers within the fibers of the hair as it grows. If collected near the scalp, hair offers a detection timeframe of about 3 months for alcohol and other substances. Hair is easy to collect, challenging to tamper with, and straightforward to transport.

A 1.5-inch portion consisting of roughly 200 hairs (the approximate width of a #2 pencil) nearest the scalp provides 100mg of hair, the perfect sample for testing and verification. For EtG, additional tests, or analyses above 10 panels, 150mg of the specimen is advisable. It's best to weigh the sample using a jeweler’s scale. Should scalp hair be unavailable, a similar quantity of body hair can be collected. Referring to head hair indicates scalp hair exclusively. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

The lab processing of a drug test result comprises four major steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a sample for the lab’s system. It involves confirming the sample's proper sealing and shipment, designating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry missing from an electronic chain of custody system.

Screening involves an initial swift assessment for drugs of abuse. Although Screening is an economical approach to exclude drug use for most samples, a positive screen must be confirmed for court admissibility. Samples presumptively positive in Screening necessitate a secondary confirmation.

For samples that test presumptively positive in Screening, further hair is extracted from the original sample and readied for Extraction. In this phase, drugs are isolated from hair at a significantly lower concentration compared to other methods (such as urine or oral fluid), underscoring why hair drug testing is the most challenging technique to execute.

Confirmation of any positive screen result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation as necessary. The complete laboratory procedure, from Accessioning to Confirmation, is audited under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations can recognize drug use for up to 90 days, unlike urine examinations which offer a shorter detection span.
• Hindrance to deception: Cheating a hair drug evaluation is quite arduous, enhancing result accuracy.
• Logs past usage: It reveals a trend of drug use over a period, rather than just the most recent usage.

Limitations:

• Recent usage detection: Drugs take approximately 5-7 days to become detectable in hair.
• Expense factor: Hair drug tests usually cost more than alternative drug testing methods.
• Result variability: Elements like hair color and personal differences in hair growth may influence drug metabolite levels in the hair.

Note: Though often called "hair follicle tests", the examination targets the hair strand instead of the 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.
