Hair Follicle Drug Testing - Dubach, LA

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair offers a prolonged history of these substances by capturing biomarkers within the fibers of the developing hair strand. When obtained near the scalp, hair can supply an approximately 3-month detection period for alcohol and other drugs. Collecting hair is straightforward, relatively hard to tamper with, and uncomplicated to transport.

A hair sample of 1.5 inches consisting of roughly 200 strands (approximating a #2 pencil) nearest the scalp will yield 100mg of hair, which is the optimal sample for analysis and confirmation. For EtG, additional tests, and/or more than 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale to weigh the material. If scalp hair isn’t present, a similar quantity of body hair can be gathered. When mentioning head hair, we specifically mean scalp hair. Body hair includes any other hair types (facial, axillary, etc.).

Process Overview

The core stages in the lab processing of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the preliminary processing of a specimen into a laboratory outfit. This process ensures the sample was correctly sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and finalizes any supplementary data entry not accompanied by an electronic chain of custody system.

Screening executes a preliminary rapid test for illegal drugs. While Screening is an economical method to negate drug use in the majority of specimens, a positive test result must be validated to be legally binding in court. Any samples with presumed positive results in Screening necessitate further confirmation.

If a sample shows presumptive positivity during the Screening phase, additional hair is extracted from the initial collection and readied for Extraction. In this part, drugs are extracted from hair at a substantially lesser concentration than in other practices (like urine or oral fluid), which is why hair drug testing is the most intricate technique to accomplish.

Confirmation for any positive Screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo cleansing prior to confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation adhering to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug assessments can identify drug usage for up to 90 days, unlike urine tests, which have a shorter detection duration.
• Challenging to falsify: It is very complex to manipulate a hair drug test, ensuring the results’ reliability.
• Reveals historical data: It offers a pattern of drug utilization over a timeline, rather than just recent consumption.

Limitations:

• Incapable of spotting recent usage: It requires around 5-7 days for drugs to be traceable in hair.
• Expense: Hair drug tests are typically more costly than other drug testing approaches.
• Disparities in findings: Factors like hair color and personal differences in hair growth can impact the concentration of drug metabolites in the hair.

Note: Although sometimes called "hair follicle tests", the analysis actually focuses on the hair strand and not the follicle beneath the scalp.

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.
