Hair Follicle Drug Testing - Darnestown, MD

What it is, How it works

Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of substance use by encapsulating biomarkers within the fibers of the growing strand. A sample acquired near the scalp can indicate alcohol and drug presence up to a 3-month period. Hair is easy to obtain, challenging to tamper with, and straightforward to transport.

A 1.5-inch section of around 200 hair strands (equivalent to a #2 pencil's thickness) near the scalp provides 100mg of hair, a perfect sample for analysis and confirmation. For EtG, add-ons, and tests exceeding 10 panels, 150mg is suggested. Evaluating the sample on a jeweler’s scale is advised. Should scalp hair be missing, a similar quantity of body hair may be used. "Head hair" refers solely to scalp hair, while "Body hair" includes all other hair varieties (facial, axillary, etc.).

Process Overview

The laboratory drug test comprises four main phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning incorporates the initial integration of a sample into a lab's system. This procedure verifies the sample was sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and concludes any further data input absent in an electronic chain of custody framework.

Screening entails a rapid assessment for commonly abused drugs. Despite being a cost-effective strategy for excluding drug use in most specimens, a positive outcome necessitates confirmation for legal acceptability. Samples with presumptively positive Screening need a supplementary verification.

A positive result in the Screening phase means extra hair from the initial sample is harvested for Extraction. During Extraction, drugs are isolated from hair in lower concentrations than alternate methods (urine or oral fluid), rendering hair drug screening challenging.

Confirmation for a positive screening result employs GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation if necessary. The complete lab process from Accessioning to Confirmation adheres to the CAP (College of American Pathologists) Hair label and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can reveal drug usage for up to 90 days, unlike urine tests with a shorter detection span.
• Difficulty to cheat: Cheating on a hair drug test is exceedingly challenging, enhancing result accuracy.
• Provides historical data: It offers an extended overview of drug use across time, not just recent usage.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair approximately 5-7 days post-use.
• Cost: Hair drug tests typically incur higher costs than other testing techniques.
• Variations in results: Variables like hair color and individual hair growth rates can influence drug metabolite concentration in hair.

Note: Although often termed "hair follicle tests," the analysis involves the hair strand itself rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Darnestown, MD, hair follicle testing proves superior to traditional urine tests. The accuracy and reliability of hair tests make them the preferred choice for detecting long-term drug use. Where urine tests fall short, hair testing steps up, providing a more comprehensive view through its extended detection window.

Urine tests capture recent use but lack the extensive detection history that hair tests offer. Thus, for a thorough assessment, hair testing beats urine testing in reliability and detection range.

Extended Detection Window

With a detection window extending up to 90 days, hair follicle testing in Darnestown, MD, offers unparalleled insight into a person's substance use history. Employers gain a comprehensive view of behavior over time, aiding better decision-making processes.

Unlike shorter-term tests, hair testing provides an extensive drug use history, offering peace of mind by revealing patterns over weeks and months, rather than days.

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.
