Hair Follicle Drug Testing - Janesville, MN

What it is, How it works

Hair tests have become an effective means for identifying drug and alcohol usage. Hair records a prolonged history of substance use by embedding biomarkers in the fibers of the hair as it grows. When collected near the scalp, hair offers up to a 3-month detection period for alcohol and substances. Collection is straightforward, challenging to tamper with, and simple to transport.

A sample measuring 1.5 inches and containing approximately 200 hair strands (equivalent to a #2 pencil) from the scalp yields 100mg, the optimal quantity for screening and confirmation. For EtG, additional tests, or tests over 10 panels, 150mg of the sample is suggested. It's advisable to weigh the specimen with a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair can be collected. References to head hair specifically mean scalp hair. Body hair includes other varieties (facial, armpit, etc.).

Process Overview

The procedure for analyzing drug test results in a laboratory includes Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the phase where a sample is initially processed into the laboratory system. It entails ensuring the sample was sealed and delivered correctly, allotting a random LAN (Laboratory Accessioning Number), and filling in any additional information absent in an electronic chain of custody system.

Screening provides an initial test for drugs of misuse. Although Screening is a cost-efficient method to exclude drug use in most samples, court-admissible results require confirmation of any positive screen. Any samples presumptively positive in Screening will need further confirmation.

In cases where Screening is presumptively positive, additional hair is taken from the original sample to prepare for Extraction. Here, drugs are extracted from hair at a lower concentration compared to other methods (e.g., urine or saliva), making hair drug testing the most challenging method to execute.

Confirmation of any Screening positivity is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive receive a wash before confirmation as required. The entire laboratory sequence from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests trace drug use for as long as 90 days, unlike the briefer detection span of urine tests.
• Difficult to evade: Tampering with hair drug tests is challenging, improving result reliability.
• Consistent data: Offers a pattern of drug use over time, not only immediate use.

Limitations:

• Doesn’t reveal recent use: It requires about 5-7 days for drug presence to appear in hair.
• Expense: Hair drug tests are typically dearer than alternative drug testing approaches.
• Result inconsistencies: Drug metabolite levels may vary due to hair color and individual hair growth differences.

Note: Although commonly termed "hair follicle tests", the examination pertains to the hair shaft and not the follicle beneath the skin.

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.
