Hair Follicle Drug Testing - Avondale, LA

What it is, How it works

Hair analysis is increasingly recognized as an effective method for identifying the use of drugs and alcohol. Hair captures a prolonged history of alcohol and other drugs by embedding biomarkers within the strands of hair as they grow. When taken at the scalp, hair can show substance use for approximately up to a 90-day period. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch sample consisting of about 200 hair strands (comparable to a #2 pencil size) near the scalp amounts to 100mg, which is the optimal sample size for both screening and verification. For EtG, additional requirements, or tests exceeding 10 panels, 150mg is advised. It's ideal to weigh the sample using a jeweler's scale. If scalp hair is not accessible, an equivalent amount of body hair can be taken. When mentioning head hair, we refer solely to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

The four key phases in the laboratory handling of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial handling of a sample into a lab’s system. This involves ensuring the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry not covered by an electronic chain of custody system.

Screening consists of a preliminary swift assessment for drugs of abuse. Although Screening is a cost-effective method for eliminating drug use for most samples, a positive screen requires confirmation for court admissibility. Samples that are tentatively positive from Screening necessitate further confirmation.

Should a sample test potentially positive in Screening, additional hair is extracted from the original sample and readied for Extraction. Here, drugs are extracted from hair at much lower concentrations compared to other approaches (such as urine or oral fluid), making hair drug testing the most challenging approach to execute.

Confirmation of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation when necessary. The entire process from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug use for up to 90 days, whereas urine tests have a more limited detection period.
• Hard to falsify: It is considerably difficult to deceive a hair drug test, enhancing accuracy.
• Offers historical insight: It can depict a pattern of drug use over time, beyond just recent usage.

Limitations:

• Incapable of recent detection: Drugs usually take about 5-7 days to be noticeable in hair.
• Expense: Hair drug assessments tend to be pricier than other testing methods.
• Result inconsistencies: Elements such as hair color and personal differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Though often referred to as "hair follicle tests", the analysis focuses on the hair strand rather than the hair 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.
