Hair Follicle Drug Testing - Red Chute, LA

What it is, How it works

Utilizing hair testing is seen as an efficient approach for identifying drug and alcohol consumption. Hair retains a historical record of substance use by capturing biomarkers within the hair strand as it grows. Collecting hair near the scalp allows for detection capabilities of up to about three months for substances like alcohol and other drugs. The process of hair collection is straightforward, poses challenges for tampering, and is easily transportable.

A 1.5-inch sample consisting of roughly 200 hair strands (approximately the thickness of a #2 pencil) taken from the scalp will yield a 100mg specimen, which is optimal for both screening and confirmation tests. For additional testing such as EtG, expanded panels, or beyond 10 panels, it is advisable to obtain 150mg of the specimen. We advise using a jeweler's scale for weighing the specimen. If scalp hair cannot be obtained, an equivalent quantity of body hair may be utilized. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The procedure for processing a drug test result in the laboratory encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.

The Accessioning stage involves the initial incorporation of a sample into the laboratory's system. This includes verifying proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry not supplied by an electronic chain of custody.

Screening provides an initial quick evaluation for substances of abuse. While Screening offers an economical way to eliminate drug usage for most samples, a positive result requires confirmation for legal acceptability. Samples showing presumptive positivity in Screening necessitate secondary validation.

If Screening indicates a presumptive positive, additional hair is extracted from the initial sample and prepared for Extraction. In this phase, substances are extracted from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), resulting in hair drug screening being the most complex methodology.

Positive Screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are washed before Confirmation as needed. The complete lab process from Accessioning through Confirmation is reviewed under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection timeframe: Hair tests can identify drug usage for a period of up to 90 days, unlike urine tests, which offer a shorter detection period.
• Highly reliable: The hair drug test is notoriously difficult to manipulate, ensuring more accurate outcomes.
• Provides usage patterns: It offers insight into drug usage trends over time, as opposed to solely recent use.

Limitations:

• Incapability of detecting recent use: It typically takes 5-7 days for drugs to appear in hair.
• Higher costs: Hair drug tests tend to be pricier compared to other methods of drug testing.
• Result variability: Factors such as hair color and individual hair growth differences can impact drug metabolite concentrations in hair.

Note: Though often labeled as "hair follicle tests", this testing process targets 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.
