Hair Follicle Drug Testing - St. Robert, MO

What it is, How it works

The use of hair testing has gained traction as an effective method for identifying alcohol and drug consumption. The fibers in growing hair strands capture biomarkers, offering a prolonged record of substance use. When the sample is taken near the scalp, it can offer a detection window of roughly 3 months for both alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and hassle-free to transport.

An ideal screening and confirmation sample consists of a 1.5-inch segment from approximately 200 strands of hair, equivalent to the thickness of a #2 pencil, yielding about 100mg of hair. For EtG, add-ons, or testing exceeding 10 panels, 150mg of the sample is advisable. Utilizing a jeweler’s scale for weighing the sample is suggested. In the absence of scalp hair, a similar quantity of body hair can be collected. The term “head hair” specifically refers to scalp hair, while “body hair” includes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four main steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase of handling a sample into a lab’s system. It involves verifying the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and inputting any additional data not included via an electronic chain of custody system.

Screening is a preliminary assessment for substances of abuse. While Screening cost-effectively rules out drug use in most samples, any positive results must be confirmed for legal admissibility. Presumptively positive samples in Screening require further confirmation.

For samples presumptively positive during Screening, more hair is extracted from the original sample and readied for the Extraction phase. Here, drugs are separated from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), explaining the complexity of hair drug screening.

Any positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS methods. Before confirmation, presumptive positive samples undergo washing as necessary. The entire lab process is scrutinized from Accessioning through Confirmation, encompassing both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests can identify drug use for up to 90 days, in contrast to shorter detection periods of urine tests.
• Challenging to deceive: Deceiving a hair drug test is notably challenging, leading to more precise results.
• Reveals historical use: It illustrates a timeline of drug use over an extended duration, beyond just recent usage.

Limitations:

• Inability to detect recent use: Approximately 5-7 days are needed for drugs to become traceable in hair.
• Higher expense: Hair drug tests tend to be more costly than other drug testing approaches.
• Result variability: Elements such as hair color and individual growth differences can influence drug metabolite concentration in hair.

Note: Despite the common term "hair follicle tests," the analysis focuses on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in St. Robert, MO, outperforms traditional urine testing significantly. The major advantage lies in its superior detection accuracy and chemical stability. Unlike urine tests, hair tests retain drug markers for extended periods and are less susceptible to temporary fluctuations in substance presence.

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.
