Hair Follicle Drug Testing - Laurel Park, VA

What it is, How it works

Hair testing is recognized as a formidable instrument for detecting drug and alcohol usage. Hair offers a comprehensive history of alcohol and other substances by embedding biomarkers within the fibers of the hair as it grows. When sampled near the scalp, hair can reveal a detection period extending up to around 3 months for alcohol and other substances. Hair is straightforward to collect, relatively challenging to tamper with, and simple to transport.

A sample measuring 1.5 inches containing roughly 200 hair strands (comparable to the thickness of a #2 pencil) closest to the scalp will provide 100mg of hair, which is the optimal sample size for testing and confirmation. For EtG, additional tests, and/or analyses exceeding 10 panels, a sample of 150mg is advisable. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair is not accessible, a comparable quantity of body hair can be obtained. When mentioning head hair, we refer solely to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning includes the initial incorporation of a sample into a laboratory system. This process involves ensuring that the sample was sealed and dispatched appropriately, allocating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data input not covered by an electronic chain of custody system.

Screening consists of a preliminary assessment for the presence of drugs. Even though Screening is a cost-efficient method to exclude drug usage in the majority of specimens, a positive screen requires confirmation to be permissible in court. All samples that show potential positivity in Screening necessitate subsequent confirmation.

If a sample is potentially positive during the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. In this step, drugs are isolated from hair at considerably lower concentrations compared to other methodologies (e.g., urine or oral fluid), which is why hair drug screening is regarded as the most challenging methodology to carry out.

Confirmation of any positive screening output is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo washing prior to confirmation as necessary. The entire laboratory procedure from Accessioning to Confirmation is evaluated within both the CAP (College of American Pathologists) Hair designation and the compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection period.
• Difficult to manipulate: It is exceptionally hard to falsify a hair drug test, ensuring the accuracy of the results.
• Delivers historical insight: It can depict a pattern of drug consumption over time, not merely recent use.

Limitations:

• Incapable of detecting recent use: It requires approximately 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests are typically more costly compared to other drug testing techniques.
• Result disparities: Variables like hair color and individual differences in hair growth can impact the concentration of drug metabolites in the hair.

Note: Commonly termed as "hair follicle tests", the analysis examines the hair strand rather than the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why does hair follicle testing outshine urine tests in Laurel Park, VA? The answer lies in the unmatched accuracy and reliability that hair testing brings against traditional urine analysis, ensuring superior drug detection.

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.
