Hair Follicle Drug Testing - Vining, MN

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of these substances by encasing biomarkers within its fibers. When harvested near the scalp, hair offers up to a 3-month detection period for alcohol and drugs. It is straightforward to collect, challenging to tamper with, and convenient to transport.

A 1.5-inch segment of approximately 200 hair strands, similar in size to a #2 pencil, taken closest to the scalp provides 100mg, the perfect sample for initial and confirmatory tests. For EtG, add-ons, and/or tests exceeding 10 panels, a 150mg sample is preferred. It is advised to use a jeweler’s scale for specimen weight. If scalp hair is unavailable, an equivalent quantity of body hair may be used. When mentioning head hair, we refer exclusively to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result comprises four major stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial processing of a sample into a lab’s system. This procedure ensures the sample was properly sealed and shipped, assigns a random Laboratory Accessioning Number (LAN), and completes any additional data entry not covered by an electronic chain of custody.

Screening is a preliminary swift check for drugs of abuse. Although it is a cost-effective approach for ruling out drug use in most samples, a positive screening outcome must be confirmed to be legally valid. Samples that are presumptively positive in Screening necessitate secondary confirmation.

When a sample tests presumptively positive in Screening, more hair from the original specimen is prepared for Extraction. This phase extracts drugs from hair at a lesser concentration than other methods (e.g., urine or oral fluid), rendering hair drug testing as the most challenging method to conduct.

Any positive screening result requires Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if necessary. The entire laboratory workflow from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug exams provide up to a 90-day detection span, unlike urine tests with a shorter timeframe.
• Hard to deceive: Cheating a hair drug test is extremely difficult, enhancing result accuracy.
• Offers historical insights: It delivers a usage pattern over time, not just recent consumption.

Limitations:

• Lacks recent use detection: Drugs become detectable in hair approximately 5-7 days after usage.
• Expense: Hair drug assessments generally incur higher costs than other testing approaches.
• Result variability: Factors like hair color and individual growth variations can influence drug metabolite concentrations in hair.

Note: Commonly known as "hair follicle tests", these tests analyze the hair strand, not the scalp's hair 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.
