Hair Follicle Drug Testing - Lowry City, MO

What it is, How it works

Hair analysis is now regarded as an effective means for detecting the use of substances like drugs and alcohol. Hair captures long-term evidence of alcohol and drug consumption by securing biomarkers within the strands as they grow. When hair is collected near the scalp, it can reveal a drug or alcohol history dating back up to roughly three months. Hair collection is uncomplicated, relatively tamper-proof, and simple to transport.

A 1.5-inch section of approximately 200 hairs (about pencil-sized) closest to the scalp equates to 100mg, the optimal amount for testing and verification. For EtG, additional tests, or tests exceeding 10 panels, a 150mg sample is preferred. It's advisable to measure the sample with a jeweler's scale. Should head hair be unavailable, an equivalent portion of body hair is acceptable. The term "head hair" specifically refers to scalp hair. "Body hair" encompasses other types like facial and axillary hair.

Process Overview

The core steps in processing a laboratory drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into the lab system. This process verifies proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent from an electronic chain of custody system.

Screening is a preliminary assessment for drugs of abuse. Although cost-efficient for disqualifying drug use in most cases, a positive screen requires confirmation for legal acceptability. Presumptive positives during Screening need subsequent confirmation.

In cases of presumptive positive during Screening, additional hair from the original sample is used for Extraction. During Extraction, drugs are drawn from hair at concentrations significantly lower than those in other testing methods such as urine or oral fluid, making hair drug testing a notably challenging method.

Confirmation of a positive screen is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, samples with presumptive positives undergo washing as necessary. The entire laboratory process, from Accessioning to Confirmation, is subject to review under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, in contrast to urine tests with a shorter timeframe.
• Hard to manipulate: Cheating a hair drug test is highly challenging, thus ensuring more reliable results.
• Tracks usage history: It reveals patterns of drug use over time, instead of only indicating recent use.

Limitations:

• Non-detection of recent use: It takes roughly 5-7 days for drugs to become traceable in hair.
• Expense: Generally, hair drug testing costs more than other testing methodologies.
• Result variability: Variables like hair color and individual hair growth differences can influence drug metabolite levels in the hair.

Note: Despite commonly being termed "hair follicle tests," the analysis targets the hair strand itself rather than 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.
