Hair Follicle Drug Testing - Allport, PA

What it is, How it works

Hair analysis is recognized as an effective method for detecting substance use, offering an extended history of alcohol and drug intake through the entrapment of biomarkers within the hair fibers. By collecting hair near the root, one can achieve a detection reach of up to approximately three months for alcohol and drugs. Hair collection is straightforward, difficult to tamper with, and simple to transport.

A 1.5-inch lock of roughly 200 hairs (similar in size to a #2 pencil) nearest to the scalp provides 100mg of hair, the optimal sample for both screening and confirmation. For EtG, additional testing beyond 10 panels, 150mg of hair is advisable. It's recommended to use a jeweler’s scale for weighing. In the absence of scalp hair, a comparable amount of body hair is suitable for collection. The term head hair pertains solely to scalp hair, while body hair encompasses other types (such as facial and axillary hair).

Process Overview

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

Accessioning marks the first phase, where a sample is integrated into the lab's system. This step entails confirming proper sealing and shipment of the sample, assigning a LAN (Laboratory Accessioning Number), and completing any extra data entry not handled by an electronic chain of custody system.

Screening delivers an initial rapid assessment for substances of abuse. Although screening is cost-effective, a positive screen needs confirmation for court admissibility. Samples deemed presumptively positive during screening must undergo confirmation.

For samples deemed presumptively positive during Screening, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are isolated from hair, achieving lower concentrations than methodologies like urine or oral fluid testing, making hair drug testing the most challenging to conduct.

GC/MS, GC/MS/MS, or LC/MS/MS are used for confirming any positive Screen results. All presumptive positive samples undergo washing before confirmation as required. From start to finish, the lab process—from Accessioning to Confirmation—follows guidelines under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Tests can uncover drug use up to 90 days, whereas urine tests offer a briefer detection range.
• Hard to manipulate: It's incredibly challenging to cheat on a hair drug test, ensuring more trustworthy results.
• Yields historical usage patterns: It uncovers long-term substance use trends, not just recent consumption.

Limitations:

• Inability to detect recent intake: Drugs require about 5-7 days to become detectable in hair.
• Expense: Hair drug tests typically have a higher cost compared to other testing methods.
• Result variability: Hair color and personal hair growth differences can influence metabolite concentrations in the hair.

Note: Commonly mislabeled as "hair follicle tests", the examination focuses on the hair strand rather than the scalp-based hair follicle.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Allport, PA
Hair testing offers distinct advantages over traditional urine tests: superior accuracy and reliability in substance detection.

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.
