Hair Follicle Drug Testing - Arthur, IL

What it is, How it works

Hair testing has gained recognition as an effective means for identifying drug and alcohol consumption. Hair serves as a repository of long-term usage history by embedding biomarkers within the strands of hair as it grows. When extracted from the area close to the scalp, hair can offer a detection window of up to about three months for alcohol and drugs. Collection is straightforward, tampering is challenging, and shipping is convenient.

A specimen comprising 1.5 inches of roughly 200 hair strands (equivalent to the size of a #2 pencil) nearest the scalp yields approximately 100mg of hair, which is optimal for screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a specimen of 150mg is advisable. It's suggested to weigh the sample using a jeweler’s scale. If scalp hair is lacking, a comparable quantity of body hair can be collected. In discussing head hair, the reference is strictly to scalp hair; body hair encompasses all other hair types, such as facial and axillary hair.

Process Overview

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

During Accessioning, the sample undergoes initial processing into the laboratory's system. This step ensures that the sample was sealed and transported appropriately, assigns a unique LAN (Laboratory Accessioning Number), and completes any additional data entry absent from the electronic chain of custody.

Screening provides a preliminary, rapid evaluation for substances of abuse. Although cost-effective in excluding drug usage in most samples, a positive screen necessitates confirmation for courtroom admissibility. Any samples showing a presumptive positive in Screening require further confirmation.

If a sample tests presumptively positive during Screening, additional hair is extracted from the original specimen for Extraction. In this phase, drugs are retrieved from hair at concentrations lower than other techniques (e.g., urine or oral fluid), which is why hair drug screening is particularly challenging to perform.

The Confirmation of positive results arises via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, any presumptive positive samples are subjected to washing as required. The laboratory procedure from Accessioning through Confirmation undergoes scrutiny according to the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can detect usage for up to 90 days, whereas urine tests possess a much shorter detection window.
• Reduced potential for deception: It's exceedingly challenging to manipulate a hair drug test, ensuring more trustworthy results.
• Reveals historical patterns: It offers insights into drug use patterns over an extended span, not merely recent consumption.

Limitations:

• Inability to detect recent usage: It requires approximately 5-7 days for drugs to become detectable in hair strands.
• Expense: Hair drug tests typically incur higher costs compared to other testing methodologies.
• Result variability: Factors like hair color and individual hair growth variations can influence drug metabolite concentrations in hair.

Note: Although often known as "hair follicle tests," the test analyzes the hair strand itself, not the hair follicle below the scalp

Why Hair Follicle Testing Beats Urine Testing

Hair testing in Arthur, IL surpasses traditional urine tests in detection accuracy and reliability. With extended detection windows, it's a superior choice for ensuring thorough screening.

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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
