Hair Follicle Drug Testing - Grosse Tete, LA

What it is, How it works

Hair analysis is now recognized as a potent method for the identification of drug and alcohol consumption. Hair offers a prolonged record of alcohol and other substances by capturing biomarkers within the fibers of the developing hair strand. When taken near the scalp, hair can offer nearly a 3-month detection period for alcohol and various drugs. Hair collection is straightforward, relatively resistant to tampering, and simple to send.

A 1.5-inch segment of about 200 hair strands (roughly the size of a #2 pencil) closest to the scalp provides 100mg of hair, which is the optimum sample for both screening and confirmation. For EtG additions and/or screenings beyond 10 panels, 150mg of the specimen is advised. We suggest measuring the specimen with a jeweler's scale. If scalp hair is not an option, a comparable quantity of body hair may be used. When discussing head hair, we exclusively refer to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The principal steps in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning handles the initial processing of a sample into the lab's system. This step verifies that the sample was correctly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entry not provided by an electronic chain of custody system.

Screening provides an initial rapid assessment for drugs of abuse. Though Screening efficiently rules out drug usage in most samples, a positive screen must be confirmed for legal admissibility. Any samples deemed presumptively positive in Screening require secondary confirmation.

If a sample is flagged presumptively positive in the Screening phase, additional hair is extracted from the initial specimen for the Extraction process. Here, drugs are removed from hair at much lower concentrations than other methods (e.g., urine or oral fluid), which is why hair drug testing is the most challenging methodology to execute.

Confirmation of any positive Screening finding is done via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleaned before confirmation as necessary. The entire lab process from Accessioning through Confirmation is assessed under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection timeframe: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests which have a shorter detection period.
• Hard to manipulate: Cheating a hair drug test is very difficult, making results more reliable.
• Offers historical insight: It can indicate a pattern of drug use over time, not just recent use.

Limitations:

• Can't detect recent use: Drugs take about 5-7 days to be traceable in hair.
• Expense: Hair drug testing is generally more costly than other drug testing techniques.
• Results variability: Factors like hair color and personal differences in hair growth can impact the concentration of drug metabolites in the hair.

Note: While commonly termed "hair follicle tests," the analysis focuses on the hair strand, 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. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis.
