Hair Follicle Drug Testing - Patrick Springs, VA

What it is, How it works

Hair drug testing has become a recognized method for identifying drug and alcohol consumption. Hair captures biomarkers within the fibers of its growing strand, offering an extended history of substances like alcohol and drugs. When sampled close to the scalp, hair analysis can reveal drug and alcohol use over a span of up to 3 months. Collecting hair is straightforward, challenging to tamper with, and simple to transport.

A sample size of 1.5 inches, consisting of approximately 200 hair strands (roughly the diameter of a #2 pencil), equates to about 100mg, which is the perfect quantity for both screening and confirmation. For tests involving EtG, additional panels, or those with more than 10 panels, 150mg of hair is advisable. We suggest weighing the sample using a jeweler's scale. Should scalp hair be inaccessible, a comparable quantity of body hair may be substituted. When we mention head hair, we are exclusively referring to scalp hair. Body hair encompasses other types (e.g., facial, axillary).

Process Overview

The primary stages in processing a drug test result in the lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the preliminary integration of a sample into the lab's system. This step confirms the sample was secured and sent appropriately, assigns a random LAN (Laboratory Accessioning Number), and enters any extra information not available through an electronic chain of custody.

Screening offers an initial check for substances of abuse. Although Screening serves as a cost-efficient method for excluding drug use in most samples, any positive findings must undergo confirmation to hold up legally. Samples with preliminary positive results require further verification through Confirmation.

Should a sample yield a presumptive positive during Screening, additional hair is extracted from the initial portion and processed in the Extraction phase. Here, drugs are extracted from hair at a notably lower concentration than alternative methods (e.g., urine or oral fluid), underscoring why hair drug testing is considered one of the most complex methods.

Confirmation for any positive results from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo washing as necessary before Confirmation. Each laboratory stage from Accessioning to Confirmation is subject to review under both the CAP (College of American Pathologists) Hair specification and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection period: Hair tests can detect drugs for as long as 90 days, whereas urine tests offer a shorter detection span.
• Hard to manipulate: The reliability of hair testing is high due to the difficulty in manipulating results.
• Historical perspective: Such tests can chart drug use patterns over time, beyond just recent usage.

Limitations:

• Cannot identify recent consumption: It takes around 5-7 days for drugs to appear in hair.
• Expense: Hair tests generally cost more than other methods of drug testing.
• Result variability: Hair attributes like color and individual growth differences can influence drug metabolite levels.

Note: Though often named "hair follicle tests", the examination evaluates the hair strand itself, not the follicle below the scalp

Why Hair Follicle Testing Beats Urine Testing

Why Choose Hair Follicle Testing over Urine Testing in Patrick Springs, VA Hair testing provides a superior detection period over 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.
