Hair Follicle Drug Testing - Summerhill, PA

What it is, How it works

Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. Through incorporating biomarkers into the fiber matrix of the hair, it offers insight into substance use over an extended period. When hair from near the scalp is collected, it can reveal substance use information for up to three months. The collection process is straightforward, tampering is challenging, and shipping is uncomplicated.

A sample measuring 1.5 inches and consisting of approximately 200 strands (equivalent to the width of a #2 pencil) near the scalp yields 100mg of hair, which is optimal for initial testing and verification. For EtG, additional substances, or tests exceeding 10 panels, 150mg of the specimen is advisable. We suggest using a jeweler’s scale for specimen weighing. Should scalp hair not be accessible, a comparable amount of body hair can be utilized. Head hair specifically refers to scalp hair, whereas body hair encompasses other types like facial or axillary.

Process Overview

The primary stages of laboratory drug test processing include Accessioning, Screening, Extraction, and Confirmation.

The Accessioning phase involves registering a sample into a lab system. This step entails confirming proper sealing and shipping of the sample, assigning a random Laboratory Accessioning Number (LAN), and completing additional data input not provided by an e-chain of custody.

Screening acts as an initial evaluation for substance abuse. Though cost-effective for negating drug use in most cases, a positive Screening requires validation for legal admissibility. Samples that test presumptively positive require further confirmation.

Should a sample register as presumptively positive during Screening, additional hair is used for the Extraction phase. At this stage, drug compounds are isolated from hair at significantly lower concentrations compared to other methods such as urine or saliva, underscoring the challenge of hair drug screening.

Verification of any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that test presumptively positive are cleansed before confirmation as necessary. The entire process, from Accessioning to Confirmation, is vetted under the CAP (College of American Pathologists) Hair standard and the ISO / IEC 17025 accreditation.

Benefits of hair drug testing:

• Extended detection period: Hair testing can identify drug consumption up to 90 days, whereas urine tests are more limited in duration.
• Testing integrity: The complex nature of hair testing makes it resistant to tampering, enhancing accuracy.
• Insight over time: The results provide a comprehensive overview of substance habits rather than recent use alone.

Drawbacks:

• Delay in detection: Hair tests require approximately 5-7 days to reflect drug use.
• Expense: Hair tests generally incur higher costs compared to other methods.
• Result variability: Differences like hair color and growth rate may impact drug metabolite levels in hair.

Note: Despite being called "hair follicle tests", it is important to understand these tests assess the strand rather than the follicle beneath the skin.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing is increasingly favored over urine tests in Summerhill, PA, due to its superior detection capabilities. Unlike urine tests, hair follicle testing offers a longer detection window, capturing drug usage over 90 days.

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.
