Hair Follicle Drug Testing - Chauvin, LA

What it is, How it works

Hair testing has emerged as an effective method for identifying drug and alcohol consumption. By embedding biomarkers within the growing hair fibers, hair offers a chronological account of substance use. When sampled near the scalp, it can detect alcohol and other drugs for up to approximately 3 months. The process of hair collection is straightforward, difficult to tamper with, and convenient for shipping.

A 1.5-inch length consisting of around 200 hair strands (roughly the thickness of a #2 pencil) adjacent to the scalp yields 100mg of hair, the preferred quantity for screening and validation. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is advisable. A jeweler’s scale should be used for weighing the specimen. When scalp hair isn't available, an equivalent quantity of body hair can be collected. "Head hair" refers specifically to scalp hair, whereas "body hair" includes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four crucial stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial integration of a sample into the laboratory system. This step includes ensuring the sample's secure sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and performing any extra data entry not covered by an electronic chain of custody method.

Screening provides an initial rapid assessment for drug presence. While it is a cost-efficient means to discount drug usage in most cases, any positive screen necessitates confirmation to be legally valid. Samples that test presumptively positive in this stage require further confirmation.

Should a sample show a presumptive positive result during Screening, additional hair is taken from the initial sample for Extraction. In this phase, drugs are extracted from hair at lower concentrations compared to alternative methods (e.g., urine or oral fluid), making hair drug screening particularly challenging.

Confirmation of any positive screening outcome is carried out through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive results are cleansed before confirmation as needed. The entire laboratory procedure, from Accessioning to Confirmation, is audited under both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug tests can identify drug use for a period of up to 90 days, compared to urine tests that offer a shorter detection span.
• Challenge to manipulate: It is extremely challenging to falsify a hair drug test, ensuring greater accuracy of the results.
• Offers historical insights: It provides a record of drug use over time rather than only recent consumption.

Limitations:

• Inability to detect recent usage: Detectability of drugs in hair takes around 5-7 days.
• Expense: Hair drug testing typically costs more than other drug testing techniques.
• Result variations: Elements such as hair color and personal differences in hair growth can impact drug metabolite concentration in hair.

Note: Although frequently termed as "hair follicle tests", this analysis examines the hair strand and not 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.

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. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix.
