Hair Follicle Drug Testing - Larto, LA

What it is, How it works

Hair testing is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair captures a long-term record by embedding biomarkers within the hair strand as it grows. When collected near the scalp, hair offers a detection period of up to approximately three months for alcohol and other substances. Hair collection is straightforward, hard to tamper with, and easy to transport.

A 1.5-inch section of around 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, additional tests, and/or those exceeding 10 panels, a sample of 150mg is advised. We suggest using a jeweler’s scale for weighing the sample. If scalp hair is not present, an equivalent amount of body hair can be obtained. When we mention head hair, we specifically mean scalp hair. Body hair encompasses all other forms (facial, axillary, etc.).

Process Overview

There are four primary procedures in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial entry of a sample into the lab’s system. This step includes confirming that the sample was properly sealed and sent, assigning it a random LAN (Laboratory Accessioning Number), and completing any necessary data input not already provided by an electronic chain of custody system.

Screening comprises a preliminary examination for substances of abuse. While it’s an economical approach to exclude drug use for most samples, a positive result requires confirmation to be legally valid. Samples with presumptive positives in Screening need further confirmation.

Should a sample be presumptively positive during Screening, additional hair is extracted from the initial sample for the Extraction process. Here, drugs are drawn from the hair at concentrations much lower than other methods (e.g., urine or oral fluid), rendering hair drug testing the most complex methodology.

Any positive Screening outcome undergoes Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before Confirmation as necessary. The lab processing from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, in comparison to urine tests which have a less prolonged detection period.
• High integrity: It is exceptionally challenging to manipulate a hair drug test, enhancing the accuracy of results.
• Offers historical insight: It can reveal a pattern of substance use over time, rather than merely recent usage.

Limitations:

• Inability to identify recent use: It takes about 5-7 days for drugs to be detectable in hair.
• Expense: Hair drug testing is typically costlier than other methods.
• Result variability: Factors like hair color and personal differences in hair growth can influence drug metabolite concentration in hair.

Note: Although often termed "hair follicle tests", the analysis performed examines the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Larto, LA, hair follicle testing surpasses traditional urine testing, offering superior detection and reliability. Not only does hair testing provide a comprehensive analysis over a longer detection window, but its accuracy in revealing substance use sets it apart from urine tests.

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.
