Hair Follicle Drug Testing - Center Line, MI

What it is, How it works

Hair screening has emerged as an influential approach for detecting drug and alcohol consumption. Hair can encapsulate a prolonged record of alcohol and drug use by capturing biomarkers within the growing hair strand fibers. When procured near the scalp, hair can offer up to a 3-month detection timeframe for drugs and alcohol. Hair is straightforward to collect, relatively resistant to tampering, and convenient to transport.

A 1.5-inch portion comprising roughly 200 hair strands (approximately the width of a #2 pencil) positioned nearest to the scalp will yield 100mg of hair, the optimal sample for screening and verification. For EtG, additional tests, and assessments exceeding 10 panels, 150mg of the specimen is advisable. We suggest weighing the specimen on a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair can be collected. When mentioning head hair, it refers solely to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

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

Accessioning entails the introductory processing of a sample into a laboratory's database. This encompasses verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent in an electronic chain of custody system.

Screening consists of a preliminary rapid assessment for drug abuse. While Screening is an economical approach to exclude drug use in most samples, a positive screen must be validated for court admissibility. Samples that return presumptive positives in Screening necessitate an additional confirmation.

If a sample is presumptively positive during the Screening stage, additional hair is sourced from the initial sample and prepared for Extraction. This stage involves extracting drugs from hair at a substantially lower concentration than alternative methodologies (e.g., urine or oral fluid), rendering hair drug screening the most challenging methodology to execute.

Confirmation of any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The complete laboratory process, from Accessioning to Confirmation, undergoes review 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 screenings can identify drug use for a period of up to 90 days, unlike urine screenings which possess a shorter detection period.
• Challenging to manipulate: It is exceedingly challenging to manipulate a hair drug screening, enhancing result accuracy.
• Reveals historical usage data: It can illustrate a pattern of drug usage over time, not merely recent use.

Limitations:

• Incapable of detecting recent usage: It takes roughly 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug screenings generally incur higher costs compared to other drug testing methods.
• Result variations: Elements like hair color and personal hair growth differences can influence the concentration of drug metabolites in hair.

Note: Although often referred to as "hair follicle tests", the analysis targets the hair strand and not 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.
