Hair Follicle Drug Testing - Weedville, PA

What it is, How it works

Hair analysis is now valued as an effective means for identifying substance use, due to its ability to retain biomarkers within the hair strand over time. By sampling near the scalp, up to three months of drug and alcohol exposure can be assessed. Hair is straightforward to obtain, hard to tamper with, and simple to mail.

Obtaining a 1.5-inch segment of roughly 200 hair strands, akin to a #2 pencil, can yield the optimal 100mg sample necessary for both screening and verification. For tests like EtG, additional tests, or those exceeding 10 panels, 150mg is advised. We suggest using a jeweler’s scale for precision. If scalp hair is absent, the equivalent quantity of body hair can be gathered. "Head hair" specifically refers to scalp hair, while "body hair" covers all other types like facial, axillary, etc.

Process Overview

The primary stages in processing a drug test in the lab include Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, the sample undergoes initial laboratory registration. This entails checking proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any additional data entry missing from an electronic chain of custody system.

Screening conducts a preliminary examination for substances of abuse. Though cost-efficient for negating drug presence in most samples, any positive result here requires confirmation to be valid in legal scenarios. Thus, any samples presumptive positive in Screening mandate additional confirmation.

Presumptive positive samples from Screening lead to further Extraction by retrieving more hair from the original sample. Here, drugs are separated from the hair at much finer concentrations compared to other practices (such as urine or saliva), which makes hair drug screening notably challenging to administer.

Verification of positives is executed with GC/MS, GC/MS/MS, or LC/MS/MS technologies. All samples suggested positive undergo washing before confirmation, as necessary. Every stage, from Accessioning to Confirmation, is scrutinized following both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation terms.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests reveal drug consumption up to 90 days, surpassing urine tests with shorter detection spans.
• Challenge to falsify: Hair drug tests are exceptionally resistant to tampering, ensuring more reliable outcomes.
• Offers historical insight: These tests depict a timeline of drug use instead of recent activity alone.

Limitations:

• Inability to detect immediate use: Drugs become identifiable in hair after roughly 5-7 days.
• Expensive: Typically, hair drug tests involve higher costs compared to alternative testing strategies.
• Result variability: Hair color and individual growth variations might influence metabolite concentration in hair strands.

Note: Though commonly called "hair follicle tests", analysis is done directly on hair strands, not on the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Choosing hair follicle testing over urine tests in Weedville, PA, offers superior detection accuracy. Hair tests detect a wider range of substances and their longer detection window surpasses traditional methods. In addition to accuracy, hair tests assure reliability, as they are not as susceptible to the immediate influences that can impair urine tests' effectiveness.

Extended Detection Window

The extended detection window offered by hair follicle tests in Weedville, PA, covers up to 90 days. This time frame provides a comprehensive record of an individual's substance use history. For employers, this means making more informed decisions by seeing a clear picture of an applicant's or employee's past with substances, far beyond what urine tests can reveal.

Tamper-Resistant Testing Method

In Weedville, PA, hair follicle testing drastically reduces the chances of tampering with samples. Unlike urine tests, which can be easily adulterated, hair testing’s method ensures secure samples and reliable results. This robust testing approach helps maintain integrity and trust in the testing process, offering undeniable outcomes.

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.
