Hair Follicle Drug Testing - Johnson, OK

What it is, How it works

Hair analysis has emerged as a robust mechanism for uncovering substance and alcohol consumption. The fibers of the developing hair hold onto biomarkers, offering a long-lasting narrative of alcohol and drug presence. Collected near the scalp, a hair sample can reveal up to a 3-month window for substances. The collection process is straightforward, tampering is challenging, and it is easy to transport.

A 1.5-inch hair sample consisting of around 200 strands (roughly the size of a #2 pencil) from near the scalp yields 100mg, which is optimal for both screening and verification. For EtG, additional tests, or those exceeding 10 panels, 150mg is suggested. Utilize a jeweler’s scale for accurate measurement. If scalp hair isn't available, body hair of the same amount can be used. "Head hair" specifically means scalp hair. "Body hair" encompasses facial, axillary, and other hair types.

Process Overview

The four primary stages in laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first phase where a sample enters a laboratory’s setup. Steps include verifying proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry that an electronic chain of custody system may lack.

Screening provides an initial swift examination for substance use. While it's a cost-effective way to dismiss the majority of drug usage, positive results in Screening require further confirmation to be court-admissible. Any presumptive positives during Screening necessitate confirmation.

Should Screening yield a presumptively positive result, further hair is taken from the original specimen for Extraction. During this stage, substances are extracted from hair at concentrations lower than other methods such as urine or oral fluid, making hair drug analysis particularly challenging.

Confirmatory testing of any positive results uses GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing prior to confirmation if required. Every processing stage from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests trace drug use for up to 90 days, unlike urine tests with immediate detection windows.
• Hard to manipulate: Tampering with hair drug tests is notably difficult, ensuring accurate results.
• Reveals consumption patterns: Hair can indicate long-term usage patterns instead of current use only.

Limitations:

• Lacks detection of recent use: Drugs typically take 5-7 days to be traceable in hair.
• Expense: Hair drug tests are often pricier than alternative testing methods.
• Result variability: Elements like hair color and individual hair growth rates can influence drug metabolite levels in hair.

Note: Though referred to as "hair follicle tests", this test examines the hair strand itself and not the underlying follicle.

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.
