Hair Follicle Drug Testing - Belfast, PA

What it is, How it works

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair captures biomarkers within the strands as they grow, offering a prolonged record of substance use. When harvested near the scalp, this method can detect alcohol and drugs for a period of up to approximately three months. Hair sampling is easy to perform, challenging to tamper with, and straightforward to transport.

A sample measuring 1.5 inches long comprising around 200 hair strands (comparable to the size of a #2 pencil) near the scalp yields 100mg of hair, which is optimal for both screening and confirmation. For EtG, extended panels, and tests including over 10 panels, it is recommended to collect 150mg of hair. We suggest using a jeweler’s scale to weigh the sample. In the absence of scalp hair, similar amounts of body hair can be collected. When we mention head hair, we specifically mean scalp hair. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The laboratory process for analyzing drug test results encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first stage where a sample is logged into the laboratory’s system. This process ensures the sample is sealed and transported correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data input absent from an electronic chain of custody system.

Screening provides an initial assessment for drugs of abuse. While it is a cost-efficient approach for eliminating drug use in most samples, positive results require confirmation to be legally valid. Samples that test positive in Screening need a secondary Confirmation.

If Screening indicates a presumptive positive result, more hair is taken from the initial sample and set for Extraction. At this stage, drugs are extracted from the hair in significantly lower concentrations than alternative methods (e.g., urine or oral fluid), which makes hair drug tests particularly challenging to conduct.

Positive screening results are confirmed using methods such as GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are washed when necessary. The laboratory procedure from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair standards and accreditation under ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can reveal drug usage over a 90-day span, unlike urine tests which have a shorter detection timeframe.
• Challenging to falsify: The accuracy of hair drug tests is high due to the difficulty in compromising them.
• Supplies historical insights: It reveals patterns of drug use across time, not merely recent instances.

Limitations:

• Inability to detect recent usage: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Higher costs: Hair drug tests are typically pricier compared to other testing techniques.
• Result variability: Factors like hair color and individual growth differences can alter drug metabolite content in hair.

Note: Although often termed "hair follicle tests", the analysis targets the hair strand and not the underlying hair follicle.

Why Hair Follicle Testing Beats Urine Testing

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.
