Hair Follicle Drug Testing - Paytes, VA

What it is, How it works

Hair testing has emerged as an effective method for detecting drug and alcohol use. Hair captures biomarkers within the fibers of the growing hair strand, offering a long-term history of exposure to alcohol and other drugs. When collected near the scalp, hair can provide approximately a 3-month detection window for alcohol and other drugs. Hair is easy to collect, relatively difficult to tamper with, and straightforward to transport.

A 1.5-inch sample of about 200 hair strands (similar in size to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the ideal amount for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a specimen of 150mg is suggested. It's advisable to weigh the specimen with a jeweler’s scale. If scalp hair is unavailable, a corresponding amount of body hair may be gathered. When mentioning head hair, we refer only to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

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

Accessioning entails the initial integration of a sample into a laboratory’s system. This process involves verifying that the sample was sealed and shipped appropriately, granting a random LAN (Laboratory Accessioning Number), and fulfilling any extra data entry not managed by an electronic chain of custody system.

Screening performs an initial rapid check for illicit drugs. While Screening is an economical method to exclude drug usage on most samples, a positive screen must be confirmed for court admissibility. Samples that screen presumptively positive necessitate secondary confirmation.

If a sample shows a presumptive positive during the Screening phase, additional hair is extracted from the original specimen and is prepared for Extraction. During this phase, drugs are extracted from hair at much lower concentrations than other methodologies (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to conduct.

Confirmation of positive screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as required. The full laboratory process from Accessioning to Confirmation is reviewed under the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, as opposed to urine tests which have a shorter detection period.
• Resistant to tampering: It is highly challenging to manipulate a hair drug test, enhancing the precision of results.
• Historical usage data: It can illustrate a pattern of drug consumption over time, rather than just recent activity.

Drawbacks:

• Inability to detect recent use: Drugs are detectable in hair approximately after 5-7 days.
• Expense: Hair drug tests generally incur higher costs than alternative drug testing methods.
• Result variability: Elements such as hair color and individual hair growth fluctuations can impact the concentration of drug metabolites in hair.

Note: Although often termed "hair follicle tests", the test itself examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Superior Detection Accuracy is why hair follicle testing often surpasses traditional urine tests in Paytes, VA. Hair tests provide a clear view over a more extended period, whereas urine tests may only capture recent usage. This reliability ensures a more comprehensive understanding of substance use, making hair tests a more effective choice for those valuing thoroughness over brevity.

Extended Detection Window

In Paytes, VA, hair follicle testing provides an extended detection window, monitoring drug use for up to 90 days. This lengthy period offers employers a complete outlook on an individual's past substance use, aiding informed decision-making. Unlike brief-term tests, hair testing covers a wider time frame, revealing a detailed employment or applicant drug history.

Tamper-Resistant Testing Method

The tamper-resistant nature of hair follicle tests in Paytes, VA is a key advantage. Hair samples, once collected, are nearly impossible to adulterate, ensuring reliable and unquestionable results. This robustness in reliability elevates hair testing as a trustworthy option, significantly reducing the risk of tampered outcomes which can affect decision-making integrity.

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.
