Hair Follicle Drug Testing - Aurora, IA

What it is, How it works

Hair analysis has emerged as a valuable method for identifying drug and alcohol consumption. Hair encapsulates biomarkers within the fibers of the growing strand, offering an extended history of alcohol and substance use. When gathered from near the scalp, hair reveals a detection window of up to around three months for drugs and alcohol. Collecting hair is straightforward, hard to tamper with, and convenient to transport.

A segment measuring 1.5 inches and consisting of about 200 strands (equivalent to a #2 pencil) taken from the region closest to the scalp yields 100mg of hair, which is the optimal amount for both screening and confirmation. For tests like EtG and those exceeding 10 panels, a 150mg sample is advised. Utilizing a jeweler’s scale for weighing the specimen is recommended. In cases where scalp hair is not available, an equal quantity of body hair can be utilized. Referring to head hair specifically means scalp hair, and body hair pertains to all other types (e.g., facial, axillary).

Process Overview

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

Accessioning is the initial step in logging a sample into the lab’s system. This process involves checking the sample's seal and shipping integrity, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any data entry not covered by an electronic chain of custody system.

Screening is a preliminary test to check for substance use. Though Screening is a cost-effective approach to eliminate drug use in most samples, a positive Screening result requires confirmation to be legally valid. Samples deemed presumptively positive during Screening need a secondary confirmation.

For samples presumptively positive at the Screening phase, further hair is taken from the primary specimen and prepared for Extraction. Here, drug components are separated from hair at considerably lower concentrations compared to other methods (such as urine or oral fluid), making hair drug testing the most complex methodology.

Confirmation of a positive screening outcome is accomplished using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleaned prior to confirmation if necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is overseen according to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug consumption for up to 90 days, unlike urine tests, which have a shorter detection timeframe.
• Challenging to deceive: Hair drug tests are highly resistant to tampering, ensuring accurate results.
• Historical insights: It offers a consumption pattern over time rather than capturing only recent usage.

Limitations:

• Recent use detection: Drugs become identifiable in hair only after about 5-7 days.
• Expense: Generally, hair drug tests incur higher costs compared to other testing approaches.
• Result variability: Factors like hair color and individual differences in hair growth can influence the levels of drug metabolites in hair.

Note: Although commonly called "hair follicle tests", the examination focuses on the hair strand, not 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. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
