Hair Follicle Drug Testing - Selbyville, DE

What it is, How it works

Hair analysis is recognized as an effective means for identifying drug and alcohol consumption. The hair captures a prolonged record of drug and alcohol usage by preserving biomarkers within the strands as they grow. When strands are taken close to the scalp, they can establish up to a 90-day detection period for drugs and alcohol. Hair samples are easy to gather, hard to tamper with, and simple to transport.

A sample measuring 1.5 inches and consisting of roughly 200 hair strands (comparable to a #2 pencil in size) near the scalp yields 100mg of hair, which is the optimal amount for both screening and confirmation tests. For EtG, additional tests, or those over 10 panels, 150mg of sample is suggested. Using a jeweler's scale to measure the specimen is advisable. If scalp hair cannot be collected, an equivalent quantity of body hair is acceptable. By head hair, we mean scalp hair only, whereas body hair encompasses all other types, including facial and axillary hair.

Process Overview

The laboratory processing of a drug test involves four principal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first step where a sample is introduced to the laboratory system. Steps include ensuring the sample is properly sealed and sent, generating a unique LAN (Laboratory Accessioning Number), and completing any missing data not included in an electronic chain of custody.

Screening quickly checks for drugs of abuse initially. Although Screening is economical for eliminating drug use in most samples, a positive finding must be corroborated to be valid in legal contexts. Samples indicating a positive result in Screening necessitate a follow-up confirmation.

For samples hinting positive at the Screening stage, more hair is taken from the original specimen for Extraction. In this process, drugs are retrieved from hair at very low concentrations compared to other methods (such as urine or oral fluid), which is why hair drug testing is a challenging procedure.

Positive screenings are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo necessary washing. The complete process from Accessioning to Confirmation is monitored under both the CAP (College of American Pathologists) Hair criteria and accreditation according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair tests reveal drug use for up to 90 days, unlike urine tests with shorter detection periods.
• Hard to falsify: It's highly challenging to manipulate hair drug test results, ensuring greater accuracy.
• Historical insight: They provide an overview of drug use patterns over time, instead of just recent use.

Limitations:

• Inability to detect recent usage: Drugs become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests often cost more than other types of drug tests.
• Result variations: Factors like hair color and personal hair growth differences can influence drug metabolite concentration in hair.

Note: Although they're commonly known as "hair follicle tests", the test actually examines 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.
