Hair Follicle Drug Testing - Toponas, CO

What it is, How it works

Hair analysis has become recognized as a robust instrument for identifying substance and alcohol use. Hair retains a lasting record of alcohol and drug usage by capturing biomarkers within the strands of growing hair. When collected near the scalp, hair can offer up to around a 3-month detection timeframe for alcohol and substances. Hair is straightforward to gather, relatively tamper-resistant, and simple to transport.

A 1.5-inch sample comprising roughly 200 hair strands (similar to the dimensions of a #2 pencil) nearest to the scalp provides 100mg of hair, the optimal sample for assessment and verification. For EtG, extended panels, and/or assessments exceeding 10 panels, 150mg of the sample is suggested. We endorse measuring the sample on a jeweler’s scale. Should scalp hair be unavailable, a comparable amount of body hair can be collected. In reference to head hair, we mean scalp hair specifically. Body hair signifies all other hair types (facial hair, axillary hair, etc.).

Process Overview

The four primary stages involved in the laboratory procedure of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial entry of a sample into the laboratory’s system. This step includes ensuring the sample was sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and performing any supplementary data entry missing from an electronic chain of custody system.

Screening consists of an initial rapid assessment for substances of abuse. Though Screening is an economical approach to exclude drug consumption in most samples, any positive screen must be validated to be court-admissible. Samples that are presumptively positive in Screening demand additional confirmation.

Should a sample be presumptively positive during the Screening phase, additional hair is obtained from the original sample and prepped for Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing the most challenging methodology to execute.

Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumptively positive undergo washing prior to confirmation where necessary. The entire lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the certification 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, unlike urine tests which have a more limited detection period.
• Challenging to falsify: Manipulating a hair drug test is exceedingly difficult, enhancing the accuracy of results.
• Offers usage history: It can indicate a drug use pattern over time, not just recent consumption.

Limitations:

• Inability to detect recent use: It requires about 5-7 days for substances to be traceable in hair.
• Expense: Hair drug tests generally incur higher costs than other drug testing methodologies.
• Result variability: Influences like hair color and personal variations in hair growth can impact drug metabolite concentrations in hair.

Note: Though commonly called "hair follicle tests", the examination is conducted on the hair strand rather than 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.
