Hair Follicle Drug Testing - Castleton, IN

What it is, How it works

Hair sampling has emerged as a robust method for identifying drug and alcohol consumption. It offers an extensive timeline of alcohol and drug usage by encapsulating biomarkers within the strands of growing hair. Collected near the scalp, hair can reveal a detection span of approximately 90 days for drugs and alcohol. Hair is effortlessly collectible, challenging to tamper with, and straightforward to transport.

An ideal screening and confirmation sample consists of about 1.5-inches of hair, totaling around 200 strands (estimated to be pencil-sized), yielding 100mg. For screenings surpassing 10 panels, EtG, or additional tests, 150mg of hair is suggested. It's advisable to weigh the specimen using a jeweler's scale. In cases where scalp hair is absent, a similar quantity of body hair is suitable. Head hair pertains solely to scalp hair, whereas body hair includes all other types such as axillary and facial hair.

Process Overview

The drug testing laboratory procedure involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial sample integration into a lab’s database. Processes include ensuring proper sealing and shipment of the sample, generating an assigned LAN (Laboratory Accessioning Number), and completing any extra data input absent from an electronic chain of custody system.

Screening offers an initial fast assessment for substances of abuse. Although screening economically eliminates most negative drug usage outcomes, a positive requires verification to meet legal admissibility. Presumptive positives identified in Screening necessitate a confirmatory assessment.

Should a sample appear positive at the Screening phase, additional hair is extracted from the initial specimen for the Extraction phase. Drugs are isolated from hair at much lower concentrations compared to other methods like urine or oral fluid, establishing hair testing as exceptionally challenging.

Utilizing GC/MS, GC/MS/MS, or LC/MS/MS techniques, any positive screenings are verified. Pre-confirmation entails washing all presumed positive samples as necessary. The complete lab workflow from Accessioning to Confirmation undergoes examination under the CAP (College of American Pathologists) Hair protocols and accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug testing can trace drug use up to 90 days, whereas urine testing has a shorter timeframe.
• Challenges of deception: Hair drug testing is notoriously hard to manipulate, ensuring more precise outcomes.
• Historical pattern provision: It records a timeline of drug use rather than just recent activity.

Limitations:

• Lacks recent use detection: Drugs become recognizable in hair roughly 5-7 days after use.
• Expense: Hair testing usually involves higher costs compared to other methods of drug testing.
• Result variability: Drug metabolite concentrations may differ due to hair color and individual hair growth rates.

Note: The test, typically termed a "hair follicle test", examines the hair strand, rather than the follicle underneath 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.
