Hair Follicle Drug Testing - Cottage Grove, OR

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying alcohol and drug consumption. Hair captures a detailed history of alcohol and drug use, trapping specific indicators in the fibers of the hair as it grows. When collected from close to the scalp, hair can offer a detection period of up to three months for alcohol and drugs. It is easy to collect, difficult to tamper with, and simple to send.

A sample measuring 1.5 inches and consisting of around 200 strands (approximately the size of a #2 pencil) taken nearest the scalp yields 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, supplementary tests, or tests beyond 10 panels, a sample weighing 150mg is advised. It is suggested to weigh the sample using a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair may be used. When mentioning head hair, it refers to scalp hair exclusively. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of drug test results consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase where the sample is integrated into the lab's system. This process includes confirming that the sample was appropriately sealed and sent, generating a random LAN (Laboratory Accessioning Number), and completing any additional data required by the electronic chain of custody system.

Screening offers a preliminary, quick assessment for substances of abuse. While a cost-effective method to exclude drug usage for most samples, a positive Screening outcome requires further confirmation to be court-admissible. Samples with presumptive positive results in Screening need subsequent Confirmation.

For samples labeled presumptively positive during Screening, additional hair is taken from the original sample and prepared for Extraction. This process extracts drugs from hair at a concentration much lower than other testing methods (such as urine or oral fluid), highlighting why hair drug testing is the most complex method to conduct.

Confirmation for positive screening results is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a washing process before Confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is examined under the CAP's (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests have a more limited detection period.
• Hard to deceive: Hair drug tests are very difficult to falsify, resulting in more reliable outcomes.
• Gives historical insight: The test can reveal a pattern of drug usage over time, not just recent activity.

Limitations:

• Not effective for recent use detection: It takes around 5-7 days for drugs to become detectable in hair.
• Price: Hair drug tests tend to be more costly than other testing methods.
• Result variability: Factors such as hair color and individual hair growth differences can influence drug metabolite concentrations.

Note: Although often termed "hair follicle tests", the analysis is performed on the hair strand, not 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. 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.
