Hair Follicle Drug Testing - Evangeline, LA

What it is, How it works

The utilization of hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair serves as a long-term record of alcohol and drug use by encapsulating biomarkers within the strands as they grow. When obtained from near the scalp, hair can indicate substance use for up to three months, offering a straightforward, tamper-resistant sample that is also easy to transport.

A 1.5-inch portion consisting of approximately 200 hair strands (roughly the diameter of a #2 pencil) near the scalp yields 100mg of hair, which is optimal for analysis and results validation. For EtG, supplementary tests, and/or panels exceeding 10, a 150mg sample is advisable. It's recommended to measure the sample using a jeweler’s scale. In the absence of scalp hair, a comparable quantity of body hair is permitted. When mentioning head hair, it specifies scalp hair exclusively. Body hair encompasses all other varieties (e.g., facial, axillary, etc.).

Process Overview

Key stages in the lab processing of drug test outcomes include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a sample into the laboratory system. This step verifies that the sample was correctly sealed and transported, allocates a random LAN (Laboratory Accessioning Number), and finalizes any extra data entry as needed absent an electronic chain of custody protocol.

Screening comprises an initial swift assessment for substance misuse. Though Screening is a budget-friendly measure to exclude drug use in most samples, a positive result necessitates confirmation to be legally defendable. Samples testing positive in Screening must undergo further validation.

Should a sample yield a positive result during Screening, additional hair is extracted and readied for Extraction. Here, drug residues are isolated from hair at lower concentrations than alternative techniques (e.g., urine or saliva), underscoring the complexity of hair drug testing.

Verification of any positive outcome from Screening is executed utilizing GC/MS, GC/MS/MS, or LC/MS/MS. Any sample with a presumptive positive result is cleansed before confirmation if required. Every phase from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair guidelines and the accreditation according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair testing can reveal drug intake up to 90 days prior, in contrast to urine tests, which offer a shorter detection duration.
• Resistance to tampering: Circumventing a hair test is notably challenging, enhancing result accuracy.
• Chronicles past usage: It chronicles drug use over time, rather than merely recent consumption.

Limitations:

• Lacks immediate detection: Drugs become noticeable in hair roughly 5-7 days post-use.
• Expense: Hair tests are typically pricier than other testing methods.
• Result variability: Factors like hair color and personal differences in hair growth may influence the presence of drug byproducts in hair.

Note: Despite the term "hair follicle tests," the analysis is conducted on the hair strand, not the scalp's 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. 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.
