Hair Follicle Drug Testing - Lu Verne, IA

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair can reveal a prolonged record of alcohol and drugs by encapsulating biomarkers within the hair strand as it develops. When collected near the scalp, it offers almost a 3-month detection timeframe for alcohol and drugs. Hair is easy to collect, relatively tamper-resistant, and simple to transport.

A 1.5-inch section consisting of roughly 200 hair strands (about the thickness of a #2 pencil) next to the scalp delivers about 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, additional tests, and those exceeding 10 panels, a 150mg sample is suggested. It is advisable to weigh the sample using a jeweler’s scale. If scalp hair is not available, an equivalent volume of body hair may be substituted. When head hair is mentioned, it specifically pertains to scalp hair, whereas body hair refers to all other hair types (facial, axillary, etc.).

Process Overview

The laboratory process for handling a drug test result mainly involves four steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial management of a sample within a laboratory’s framework. This step involves checking that the sample was sealed and transported appropriately, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data input not covered by an electronic chain of custody protocol.

Screening acts as an initial rapid assessment for substance abuse. Although Screening is an economical approach to exclude drug usage in most samples, a positive outcome mandates subsequent validation for courtroom acceptability. Samples that seem positive during Screening necessitate a subsequent confirmation.

Should a sample appear positive in the Screening phase, additional hair is retrieved from the original sample for Extraction. Drugs are then extracted from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging technique to execute.

Confirmation of each positive Screening result employs GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive outcomes are washed before confirmation as required. The complete laboratory process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and conforms to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use for approximately 90 days, unlike urine tests which have a more limited detection period.
• Hard to manipulate: The chances of tampering with a hair drug test are minimal, enhancing result accuracy.
• Offers historical insights: It provides a record of drug usage over time, as opposed to only recent consumption.

Limitations:

• Incapable of detecting recent use: Drugs are not detectable in hair for a period of roughly 5-7 days post-consumption.
• Expense: Hair drug tests generally incur higher costs than other testing techniques.
• Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Though often termed as "hair follicle tests", the analysis is actually conducted on the hair strand itself and not the scalp’s hair follicle.

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.
