Hair Follicle Drug Testing - Culmerville, PA

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair can capture a long-term record of substance use by embedding biomarkers within the fibers of the hair strand as it grows. When hair is harvested near the scalp, it can offer a detection range of up to roughly three months for alcohol and other substances. Hair is easy to collect, relatively challenging to tamper with, and simple to transport.

A sample of 1.5 inches consisting of around 200 strands of hair (about the thickness of a #2 pencil) near the scalp will yield 100mg, which is the perfect quantity for both screening and confirmation. For EtG, additional tests, and/or assessments beyond 10 panels, 150mg is advisable. It is recommended to gauge the specimen's weight using a jeweler’s scale. If scalp hair isn't obtainable, an equivalent amount of body hair can be gathered. "Head hair" specifically refers to scalp hair, whereas "body hair" includes all other types of hair (such as facial and axillary).

Process Overview

The key steps in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a sample within a laboratory's framework. This step involves verifying the correct sealing and shipping of the sample, generating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.

Screening involves an initial and rapid assessment for drugs of abuse. Screening is a cost-efficient method to exclude drug usage in most samples; however, a positive indication requires confirmation to be legally acceptable. Any samples that yield a presumptive positive during Screening must undergo an additional confirmation.

Should a sample yield a presumptive positive in the Screening phase, more hair is retrieved from the primary specimen and readied for Extraction. This stage involves isolating drugs from hair at significantly lower concentrations than other methods (such as urine or oral fluid), which is why hair drug screening is notably challenging to conduct.

Confirmation of any initial positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that presumptively test positive are cleansed before confirmation if necessary. The complete laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and accreditation conforming to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair testing can identify drug use up to 90 days in the past, while urine tests have a briefer detection window.
• Resistance to tampering: Hair tests are extremely difficult to manipulate, enhancing result accuracy.
• Chronic use insights: It can reveal a pattern of drug consumption over time, not just recent usage.

Limitations:

• Cannot detect recent consumption: It requires approximately 5-7 days for drugs to appear in hair.
• Expense: Hair testing typically costs more than other testing methodologies.
• Result variability: Factors like hair color and individual differences in hair growth can influence the concentration of drug metabolites in hair.

Note: Although commonly called "hair follicle tests", the test examines the hair strand instead of the follicle beneath the scalp

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.
