Hair Follicle Drug Testing - Jarrettsville, MD

What it is, How it works

Hair testing is recognized as an effective means for identifying drug and alcohol consumption. Hair strands encapsulate biomarkers within the fibers as they grow, offering an extended historical record of substance use. When sourced near the scalp, these strands can indicate drug and alcohol presence for a period of up to about three months. The collection process is straightforward, altering the sample is challenging, and it is conveniently transportable.

A sample measuring 1.5 inches with roughly 200 hair strands (approximately the thickness of a #2 pencil) from the scalp yields 100mg, which is optimal for screening and validating results. For EtG, additional parameters, and/or testing above ten panels, a sample of 150mg is preferred. Using a jeweler’s scale for specimen measurement is advised. If scalp hair is absent, an equivalent quantity of body hair can be gathered. Notably, "head hair" specifically refers to scalp hair, while "body hair" covers all other types (facial, axillary, etc.).

Process Overview

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

During Accessioning, the sample is initially integrated into the laboratory system. Processes include ensuring proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any data entry needs beyond the scope of an electronic chain of custody system.

Screening entails a preliminary assessment for illicit substances. Though Screening is a cost-effective strategy to eliminate drug use in most samples, confirming a positive result is necessary for legal acceptance. Samples with a positive presumption in Screening require a secondary verification.

Presumptive positive samples in Screening are subject to further hair extraction from the initial specimen and prepared for Extraction. At this stage, drugs are extracted from hair at considerably lower concentrations than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug testing methodologies.

Confirmation of any positive screen outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positivity are cleaned as required before Confirmation. The comprehensive laboratory workflow from Accessioning to Confirmation is reviewed under the College of American Pathologists (CAP) Hair designation and adheres to the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify substance use for as long as 90 days, unlike urine tests which offer a shorter detection span.
• Resistance to tampering: Cheating a hair drug test is exceptionally difficult, resulting in more reliable outcomes.
• Offers a timeline of use: It reveals a trend of drug use over time, beyond just recent consumption.

Limitations:

• Inability to detect recent use: Drugs become traceable in hair approximately 5-7 days after use.
• Expense: Generally, hair drug tests incur higher costs compared to alternative testing methods.
• Result variability: Elements such as hair color and personal hair growth differences can influence drug metabolite concentration levels in hair.

Note: The term "hair follicle tests" is frequently misapplied, as the actual analysis is conducted on hair strands rather than the follicles located 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.
