Hair Follicle Drug Testing - Sandstone, MN

What it is, How it works

Utilizing hair testing has emerged as an effective method for identifying drug and alcohol use. Hair retains a long-term history of alcohol and various drugs by encapsulating biomarkers within the fibers of the hair as it grows. When extracted near the scalp, hair can offer up to a three-month detection period for alcohol and other drugs. Hair is easy to gather, somewhat arduous to tamper with, and simple to transport.

An ideal sample for screening and confirmation involves acquiring a 1.5-inch piece composed of around 200 strands of hair (resembles the thickness of a #2 pencil) closest to the scalp, supplying 100mg of hair. For EtG, supplementary testing, and/or assessments beyond 10 panels, a total of 150mg of the specimen is suggested. Measuring the specimen using a jeweler’s scale is recommended. If scalp hair isn’t accessible, an equivalent amount of body hair may be collected. When head hair is mentioned, it pertains to scalp hair only. Body hair encompasses all other forms of hair (such as facial, axillary, etc.).

Process Overview

The four core stages involved in the lab processing for a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the preliminary processing of a sample into a laboratory’s records. This step ensures that the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry not supplied by an electronic chain of custody system.

Screening performs an immediate preliminary check for drugs of abuse. Screening is a cost-efficient method to eliminate drug usage across most samples, yet a positive result necessitates confirmation to be valid in legal settings. Samples presumptively positive in Screening do require subsequent confirmation.

Should a sample be presumptively positive during the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. In this stage, drugs are extracted from hair at reduced concentrations relative to other methodologies (e.g., urine or oral fluid), illustrating why hair drug screening is a complex methodology to execute.

Confirmation for any positive screening result is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation as necessary. The complete laboratory protocol from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair criteria and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use spanning up to 90 days, as opposed to urine tests which possess a shorter detection window.
• Challenges to manipulation: Cheating a hair drug test is exceptionally challenging, which enhances result accuracy.
• Offers historical insight: It can reveal a trend in drug use over a time period, not just recent consumption.

Limitations:

• Incapable of detecting recent consumption: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests typically incur higher costs compared to other drug testing techniques.
• Result variability: Factors like hair color and individual hair growth variations can influence the concentration of drug metabolites in the hair.

Note: Although commonly termed "hair follicle tests", the actual analysis examines the hair strand rather than 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.
