Hair Follicle Drug Testing - Holt, MI

What it is, How it works

Hair examination is now regarded as an effective method for identifying drug and alcohol consumption. Hair encases biomarkers within the fibers of the developing hair strand, offering a long-term record of alcohol and drug use. When hair is taken from near the scalp, it can offer an approximate 3-month time frame for detecting alcohol and drugs. Collecting hair is straightforward, somewhat resistant to tampering, and simple to transport.

A 1.5-inch section of roughly 200 hair strands (comparable in size to a #2 pencil) near the scalp will yield 100mg of hair, the perfect sample size for testing and validation. For EtG, additional substances, or tests exceeding 10 panels, a 150mg specimen is advised. We suggest weighing the sample using a jeweler's scale. If scalp hair is unavailable, a corresponding quantity of body hair can be gathered. When mentioning head hair, it pertains solely to scalp hair, whereas body hair includes all other kinds (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result primarily involves four steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into a lab’s system. This process includes verifying the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data input not managed by an electronic chain of custody system.

Screening provides a preliminary rapid assessment for drugs of abuse. While Screening is an economical method to exclude drug usage in most samples, any positive screen must be validated for court admissibility. Samples showing presumptive positives during Screening require a secondary verification.

If Screening yields a presumptive positive, additional hair is taken from the initial sample for Extraction. This phase extracts drugs from hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug testing the most challenging methodology to execute.

Confirmation of any positive Screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation as needed. The entire lab procedure, from Accessioning to Confirmation, is audited under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection period.
• Harder to deceive: It's considerably challenging to deceive a hair drug test, enhancing result accuracy.
• Displays usage history: It can show a pattern of drug use over time, not just recent activity.

Limitations:

• Inability to detect recent use: There is a delay of approximately 5-7 days before drugs become detectable in hair.
• Expense: Hair drug tests typically cost more than alternative testing methods.
• Result variability: Elements like hair color and individual differences in hair growth can influence the presence of drug metabolites in hair.

Note: Despite often being called "hair follicle tests," the analysis itself is conducted on 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.
