Hair Follicle Drug Testing - North Potomac, MD

What it is, How it works

Hair testing is now recognized as an effective means of identifying drug and alcohol consumption. Hair offers a comprehensive history of substance use by embedding biomarkers within the hair strand's fiber. When sampled near the scalp, hair delivers an approximate 3-month detection period for substances. It is straightforward to gather, resilient to tampering, and easy to send.

A sample of 1.5 inches, consisting of roughly 200 strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is ideal for both screening and confirmation. For EtG, supplemental tests, or tests exceeding 10 panels, collecting 150mg of the specimen is advisable. The use of a jeweler’s scale for weighing the sample is recommended. If scalp hair isn't accessible, an equivalent quantity of body hair can be used. Note that when discussing head hair, it specifically refers to scalp hair only, whereas body hair encompasses all other types (facial, axillary, etc.).

Process Overview

There are four primary stages in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into the lab’s system. This step ensures the sample's proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entry not covered by an electronic chain of custody.

Screening acts as an initial rapid test for drugs of abuse. While Screening is a cost-efficient method to exclude drug use in most cases, a positive result must be confirmed for legal admissibility. Presumptive positives in Screening necessitate secondary confirmation.

For presumptive positives in the Screening phase, additional hair is taken from the original sample and readied for Extraction. During Extraction, drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Confirmation of positive screening outcomes is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are wash-treated before confirmation as warranted. The entire laboratory workflow from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Long detection period: Hair drug tests identify drug use for up to 90 days, surpassing the shorter window of urine tests.
• Hard to falsify: It is challenging to deceive a hair drug test, enhancing result accuracy.
• Chronicles historical use: It outlines a pattern of drug use over time instead of just recent activity.

Limitations:

• Cannot identify recent ingestion: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests generally cost more than other testing methods.
• Result variability: Aspects such as hair color and individual hair growth can impact metabolite concentrations in the hair.

Note: The term "hair follicle tests" is often used incorrectly; the test analyzes the hair strand rather than the follicle under the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Tests Lead over traditional urine tests in North Potomac, MD is clear. Hair testing can deliver superior detection accuracy and reliability when compared to urine tests.

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.
