Hair Follicle Drug Testing - College Park, MD

What it is, How it works

Hair testing has emerged as an influential method for identifying drug and alcohol consumption. Biomarkers are captured in the fibers of actively growing hair, providing a prolonged record of substance use. When cut near the scalp, it can offer a detection period of roughly three months for alcohol and drugs. The collection process is straightforward, moderately challenging to tamper with, and simple to mail.

An optimal sample involves a 1.5-inch segment of approximately 200 hair strands (roughly pencil-thick) nearest to the scalp, supplying 100mg of hair for screening and confirmation. For EtG, additions, or tests exceeding 10 panels, 150mg is advisable. It's best to weigh this sample using a jeweler’s scale. In the absence of scalp hair, an equivalent portion of body hair can be taken. By head hair, we mean only scalp hair. Body hair encompasses all other types (face, armpits, etc.).

Process Overview

The key phases in lab processing for a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is incorporated into the lab’s system, ensuring it was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any extra data not covered by an electronic chain of custody.

Screening offers a quick initial assessment for drugs of abuse. Although a cost-efficient way to clear most samples, a positive result needs legal admissibility, requiring further confirmation. Samples that test positive at this stage need additional verification.

If a sample tests positive initially, more hair is taken from the first sample for Extraction. Here, drugs are isolated from hair at lower concentrations than other methods (such as urine or saliva), which makes hair drug assays the toughest method to conduct.

Any positive screening is validated through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo washing before confirmation. The whole laboratory process from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests cover drug use up to 90 days, unlike the shorter range of urine tests.
• Hard to falsify: Hair drug tests resist cheating, ensuring more reliable results.
• Shows past usage: It reveals a timeline of drug use over time, beyond just recent consumption.

Limitations:

• Incapable of recent detection: Drugs appear in hair only after about 5-7 days.
• Expense: Hair drug tests tend to be pricier than other testing techniques.
• Result variability: Hair color and personal growth differences might influence drug metabolite levels in hair.

Note: Commonly termed as "hair follicle tests", the analysis is done on the hair shaft, not the follicle under the scalp

Why Hair Follicle Testing Beats Urine Testing

In College Park, MD, hair follicle testing is preferred over urine tests due to superior detection accuracy and reliability.

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.
