Hair Follicle Drug Testing - Grand Falls, MN

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol use. Hair serves as a record for long-term alcohol and drug exposure by capturing biomarkers within the hair strand fibers. When gathered close to the scalp, it can reveal up to a 3-month detection period for alcohol and drugs. Hair collection is straightforward, somewhat tamper-resistant, and easily transportable.

A 1.5-inch hair sample consisting of about 200 strands (approximately the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal quantity for tests and confirmations. For EtG, extended panels, and/or tests exceeding 10 panels, 150mg is advised. It's suggested to weigh the sample precisely using a jeweler’s scale. Should scalp hair be unavailable, an equivalent amount of body hair is collectable. References to head hair imply scalp hair exclusively. In contrast, body hair encompasses all other types (e.g., facial, axillary).

Process Overview

The crucial phases in processing a drug test result in a lab include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the primary integration of a sample into a lab’s system by ensuring proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and fulfilling extra data entries absent in an electronic chain of custody.

Screening performs a preliminary evaluation for abuse drugs. Though it is cost-effective to eliminate drug consumption for most samples, a positive outcome necessitates confirmation for legal acceptability. Samples presumptively positive in Screening demand an additional confirmation.

A sample yielding a presumptive positive during Screening activates the Extraction stage, where further hair is prepared. Here, drugs are retrieved from hair at significantly lower levels than other methods (e.g., urine or oral fluid), making hair drug screening notably challenging.

Confirmation for any positive screen occurs through GC/MS, GC/MS/MS, or LC/MS/MS. Pre-confirmation, all presumptive positive samples are cleansed as necessary. Every lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 certification.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests reveal drug consumption for up to 90 days, surpassing the shorter span of urine tests.
• Hard to deceive: Hair drug tests are difficult to compromise, ensuring more precise results.
• Presents historical data: Offers a drug use pattern over time, instead of only recent activity.

Limitations:

• Incapacity to detect recent use: Drugs begin showing up in hair around 5-7 days post-use.
• Expense: Generally, hair drug tests incur higher costs than other methods.
• Result variability: Hair color and individual growth differences can influence drug metabolite concentrations in hair.

Note: Although termed as "hair follicle tests", the method inspects the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Grand Falls, MN, hair follicle testing has shown to be superior to urine testing in several ways. One notable benefit is the extended detection period, allowing for a more thorough understanding of an individual's drug use history.

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.
