Hair Follicle Drug Testing - Big Bend, WI

What it is, How it works

The analysis of hair as a testing method has emerged as a significant means for identifying alcohol and drug consumption. By capturing biomarkers within the strands, hair offers a prolonged record of substance use. When hair is taken from near the scalp, it can offer a detection period of roughly three months for alcohol and drugs. Collecting hair is straightforward, quite resistant to tampering, and easily transported.

A sample of 1.5 inches consisting of about 200 hair strands (approximately the thickness of a #2 pencil) sourced closest to the scalp will yield 100mg, which is the optimal amount for both screening and verification. For EtG, test supplements, and/or assessments exceeding 10 panels, a specimen of 150mg is advisable. We suggest measuring the sample using a jeweler’s scale. If scalp hair is not available, a corresponding quantity of body hair may be utilized. When mentioning head hair, we refer exclusively to scalp hair. Body hair encompasses all other hair (facial, axillary, etc.).

Procedure Summary

Four primary stages are involved in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial processing of the sample into the lab's system. This comprises confirming the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing added data entry that isn’t recorded in an electronic chain of custody system.

Screening entails an initial evaluation for drug abuse. Though Screening is a cost-efficient approach to exclude drug use in most samples, a positive result needs confirmation to be valid in legal proceedings. Samples that are presumptively positive during Screening require another confirmation.

Should a sample signal a positive result in Screening, additional hair is retrieved from the primary sample and readied for Extraction. At this stage, drugs are extracted from hair at significantly smaller levels than by other techniques (e.g., urine or oral fluid), which is why hair drug testing is a challenging process.

Confirmation of any positive Screening outcome is performed utilizing GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, any presumptively positive samples are cleansed as necessary. The full lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.

Benefits of Hair Drug Testing:

• Extended detection timeframe: Hair drug assessments can reveal drug consumption for up to 90 days, unlike urine tests that have shorter periods.
• Challenges in deception: Hair drug tests are notably hard to tamper with, ensuring more precise outcomes.
• Reveals usage history: It can disclose consistent drug patterns over time instead of recent consumption alone.

Drawbacks:

• Incapability to identify recent consumption: It generally takes 5-7 days before drugs are identifiable in hair.
• Expense: Hair drug testing often incurs higher costs compared to alternate testing methods.
• Result variations: Attributes such as hair color and personal growth differences can impact the appearance of drug metabolites in hair.

Note: Commonly called "hair follicle tests", the test itself examines the hair strand instead of the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In the realm of drug testing in Big Bend, WI, hair follicle tests outshine urine evaluations due to superior accuracy and reliability.

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.
