Hair Follicle Drug Testing - Yogaville, VA

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol use. Hair captures a prolonged record of alcohol and drug intake by embedding biomarkers within the strands of hair as it grows. When sampled near the head, hair can offer up to roughly a 3-month timeframe for detecting alcohol and drugs. Hair is easy to collect, challenging to tamper with, and simple to transport.

A 1.5-inch section of around 200 strands (approximately the size of a #2 pencil) near the scalp yields 100mg of hair, which is the preferred amount for screening and confirmation. For EtG, additional tests, or tests with more than 10 panels, 150mg of hair is advised. It is recommended to weigh the sample using a jeweler’s scale. If scalp hair is not present, an equivalent quantity of body hair may be used. When mentioning head hair, it refers specifically to scalp hair. Body hair includes all other types of hair (facial, underarm, etc.).

Process Overview

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

Accessioning includes the initial preparation of a sample in the lab's system. This process confirms the sample is intact and correctly transported, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data not facilitated by an electronic chain of custody system.

Screening entails an initial, quick evaluation for drug use. Although Screening is an economical method to exclude drug use in most samples, a positive result requires confirmation to be valid in legal situations. Any samples testing presumptive positive in Screening mandate further confirmation.

If a sample suggests a positive result in Screening, more hair from the original sample is prepared for Extraction. Drugs are extracted from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most complex methodology.

Confirmation of any positive Screening result is done through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are cleaned as required before confirmation. The entire laboratory procedure from Accessioning to Confirmation is assessed under CAP (College of American Pathologists) Hair standards and accredited to ISO / IEC 17025.

Advantages of hair drug testing:

• Long detection period: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests with a shorter detection span.
• Low risk of tampering: It is extremely challenging to cheat on a hair drug test, enhancing the accuracy of the results.
• Provides a usage history: It can display a trend of drug use over time, not just recent usage.

Limitations:

• Inability to detect recent use: Drugs need approximately 5-7 days to become traceable in hair.
• Expense: Hair drug tests usually cost more than other testing methods.
• Results fluctuation: Influences such as hair color and individual hair growth variations can impact drug metabolite concentrations in hair.

Note: While often referred to as "hair follicle tests", the test itself examines the hair strand and 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.
