Hair Follicle Drug Testing - Rio, WI

What it is, How it works

Hair analysis has gained recognition as an effective means for identifying drug and alcohol consumption. The hair retains evidence of substance use by embedding biomarkers within the strands as they grow. When taken near the head, hair offers an approximate 3-month detection timeframe for substances like alcohol. Hair is easy to collect, somewhat resistant to tampering, and straightforward to transport.

Collecting a 1.5-inch piece containing around 200 hair strands (comparable to a #2 pencil in size) near the scalp yields 100mg of it, perfect for tests. For EtG, additional screens, and tests beyond 10 panels, 150mg is optimal. It's advisable to weigh the sample using a jeweler’s scale. In the absence of scalp hair, a similar amount of body hair is applicable. Reference to head hair pertains solely to scalp hair. Conversely, body hair encompasses all other types of hair like facial and axillary hair.

Process Overview

There are four core steps in processing lab drug tests: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails incorporating a sample into a laboratory’s system. This means ensuring that the sample's seal and shipment are intact, generating a random LAN (Laboratory Accessioning Number), and any additional input not featured in an electronic chain of custody system is handled.

Screening serves as an initial rapid check for substance misuse. Though it's an economical approach to exclude drug use in most samples, a positive outcome needs confirmation to hold in legal proceedings. Samples yielding presumptive positivity during Screening need further verification.

Should a sample prove presumptively positive in Screening, additional hair from the original sample undergoes Extraction preparation. During this phase, drugs are retrieved from hair at significantly low concentrations compared to other techniques (such as urine or oral fluid), rendering hair drug testing the most intricate methodology.

GC/MS, GC/MS/MS, or LC/MS/MS is utilized to confirm any positive Screening findings. Presumptively positive samples are cleansed before confirmation as necessary. The entire lab procedure from Accessioning through Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Perks of hair drug testing:

• Extended detection period: Hair drug screens can uncover drug intake for as long as 90 days, contrasting with urine tests which have a shorter detection period.
• Hard to deceive: Manipulating hair drug tests is exceptionally difficult, thereby enhancing result accuracy.
• Yields historical insight: It reveals patterns of drug intake over time, rather than just recent activity.

Constraints:

• Incapable of recent usage detection: Drugs become detectable in hair after about 5-7 days.
• Expense: Hair drug examinations typically cost more than other types of drug tests.
• Outcome variability: Elements like hair color and individual growth differences can influence the concentration of drug metabolites in the hair.

Note: Although often referred to as "hair follicle tests", the procedure itself focuses on the hair strand, 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.
