Hair Follicle Drug Testing - Takoma Park, MD

What it is, How it works

Hair sampling is now recognized as an effective method for identifying drug and alcohol consumption. Hair strands serve as a long-term record of alcohol and drug usage by capturing biomarkers in the fibers during growth. By collecting hair near the scalp, it is possible to detect alcohol and drugs for up to approximately three months. Collecting hair is straightforward, hard to tamper with, and convenient to send.

Obtaining a 1.5-inch segment with roughly 200 hair strands (comparable to the thickness of a #2 pencil) from the scalp yields about 100mg, which is the optimal quantity for both screening and verification. For EtG and more extensive tests beyond 10 panels, a 150mg sample is advisable. We suggest using a jeweler’s scale for precise specimen measurement. If scalp hair isn't available, an equivalent quantity of body hair can be used. When we talk about head hair, it specifically means scalp hair. Body hair includes all other types (like facial or axillary hair).

Procedure Summary

The main phases in processing a drug test in the lab are Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial processing of the sample into the lab’s database. This step includes confirming that the sample was securely sealed and dispatched, allotting a random LAN (Laboratory Accessioning Number), and completing any extra data input not available through an electronic chain of custody.

Screening involves a preliminary rapid examination for substances of abuse. Although Screening is a cost-saving approach for negating drug use in most samples, a positive Screening result must be substantiated for legal admissibility. Samples indicating presumptive positivity in Screening require further confirmation.

In instances of presumptive positivity during Screening, additional hair is extracted from the original sample and readied for Extraction. During this step, substances are extracted from hair at concentrations much lower than other methods (such as urine or oral fluid), making hair drug screening the most challenging technique to execute.

Any positive screening result undergoes Confirmation via GC/MS, GC/MS/MS or LC/MS/MS. All samples indicating presumptive positivity are cleansed prior to confirmation as necessary. The complete lab procedure from Accessioning to Confirmation is conducted under both CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.

Benefits of hair drug testing:

• Extended detection period: Hair tests for drugs can reveal usage for up to 90 days, unlike urine tests with shorter detection spans.
• Hard to manipulate: Cheating a hair drug test is very challenging, ensuring more reliable results.
• Historical insights: It reveals patterns of drug use over time, not merely recent usage.

Drawbacks:

• Inability to detect recent use: Drugs are usually detectable in hair only after about 5-7 days.
• Expense: Hair drug testing is typically pricier than other methodologies.
• Result variations: Factors like hair color and individual hair growth differences can impact drug metabolite concentrations.

Note: Though commonly called "hair follicle tests", the test actually evaluates the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Takoma Park, MD

Hair follicle testing provides clear advantages over urine tests, especially regarding detection accuracy and reliability. While urine tests offer a limited detection window, hair testing identifies drug use over a more extended span, offering a more comprehensive insight into the subject’s history. This efficacy makes hair testing the preferred choice in many professional and legal scenarios.

Extended Detection Window

Extended Detection Window in Takoma Park, MD

Hair follicle testing stands out due to its extended detection period, which can trace drug usage up to 90 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.
