Hair Follicle Drug Testing - Bridgetown, MD

What it is, How it works

Hair testing is increasingly regarded as an effective means for identifying drug and alcohol use. The hair provides an extended timeline by enveloping biomarkers within the fibers of the growing strand. Gathered near the scalp, hair can reveal a detection period of nearly three months for drugs and alcohol. This method is straightforward for collection, moderately challenging to tamper with, and convenient to transport.

A sample of roughly 200 strands, totaling 1.5 inches from the scalp, yields about 100mg, the optimal quantity for screening and affirmation. For EtG, add-ons, or tests surpassing 10 panels, 150mg is advisable. It is best to measure the specimen using a jeweler’s scale. Should scalp hair be inaccessible, a similar quantity of body hair can be obtained. By "head hair," we specifically mean scalp hair. In contrast, "body hair" refers to any other hair types (such as facial or axillary).

Process Overview

The key steps in processing a drug test result at the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of processing a sample in the lab system. This step includes ensuring the sample is properly sealed and shipped, assigning a random Laboratory Accessioning Number (LAN), and completing any necessary data entry not covered by an electronic chain of custody.

Screening is a preliminary check for drugs of abuse. Although cost-effective for dismissing drug usage in most samples, a positive screen needs affirmation for court submission. Any samples showing presumptive positivity in Screening require further confirmation.

If a sample demonstrates presumptive positivity in Screening, more hair is extracted from the original specimen for preparation in the Extraction stage. Drugs are extracted from the hair at significantly lower levels than other testing methods (e.g., urine or oral fluid), contributing to the complexity of hair testing.

Confirmation of any positive Screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as warranted. Each step from Accessioning to Confirmation is scrutinized under both the College of American Pathologists (CAP) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can trace drug use for up to 90 days, contrasting with the shorter detection period of urine tests.
• Difficulty in tampering: It is notably difficult to tamper with a hair drug test, enhancing result accuracy.
• Historical data provision: Hair tests offer insights into drug usage patterns over time, beyond recent usage only.

Limitations:

• Inability to detect recent use: Detecting drugs in hair requires about 5-7 days post-use.
• Expense: Hair drug tests tend to be pricier than alternative methods.
• Result variations: Aspects like hair color and growth disparities can influence drug metabolite concentration in hair.

Note: Although termed "hair follicle tests," the actual analysis is performed 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. 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.
