Hair Follicle Drug Testing - Brownville, NE

What it is, How it works

Hair assessments are recognized as a robust method for identifying drug and alcohol consumption. Hair retains a historical record of substances by embedding biomarkers in the fibers of the developing hair shaft. Samples taken near the scalp can yield up to an approximately three-month detection window for alcohol and drugs. Hair is easy to gather, relatively hard to tamper with, and simple to send off.

A 1.5-inch segment of around 200 hairs (similar to the size of a #2 pencil) closest to the scalp provides 100mg, the optimum sample amount for initial analysis and verification. For EtG, additional testing, and/or panels over ten, 150mg is suggested. Using a jeweler’s scale for weighing the sample is recommended. Should scalp hair be unavailable, a similar amount of body hair can be used. References to head hair specifically mean scalp hair. Body hair refers to all other types of hair, including facial, underarm, etc.

Process Overview

The key stages in the lab procedure for processing a drug test are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the first steps of logging a sample into a lab system. This involves checking the sample's seal and shipping integrity, allocating a random LAN (Laboratory Accessioning Number), and completing any data entry that's missing from an electronic system.

Screening is an initial rapid review for substances of abuse. Although cost-effective for eliminating most drug use claims, a positive result needs verification to be legal in court. Any sample flagged as potentially positive in Screening must undergo further Confirmation.

If a sample initiates a positive indication in the Screening phase, more hair is extracted from the original sample for the Extraction process. Here, drugs are extracted from hair at a concentration much lower than other techniques (e.g., urine or oral fluid), making hair drug testing the most challenging method to conduct.

Confirmation for any positive Screening outcome is done using GC/MS, GC/MS/MS, or LC/MS/MS. All potential positive samples are cleansed if needed before Confirmation. The full lab operation from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Detects drug consumption for up to 90 days, unlike urine tests which offer a shorter period.
• Hard to manipulate: Cheating a hair drug test is extremely difficult, providing more reliable results.
• Reflects consumption patterns: Offers an overview of drug usage over a period, rather than just recent intake.

Limitations:

• Lacks recent use detection: Drugs are detectable in hair roughly 5-7 days after use.
• Expense: Generally more costly compared to other drug testing approaches.
• Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite levels in hair.

Note: Often described as "hair follicle tests", but the test actually evaluates the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
