Hair Follicle Drug Testing - Huntsville, WA

What it is, How it works

Hair analysis is increasingly recognized as an effective means for identifying the consumption of drugs and alcohol. The fibers of a growing hair strand capture biomarkers, offering a prolonged record of substance use. A hair sample taken near the scalp can reveal drug and alcohol use over a detection period spanning up to three months. Collecting hair is straightforward, offers resistance to tampering, and is convenient for shipping.

Obtaining a 1.5-inch portion containing about 200 hair strands, roughly the size of a #2 pencil, close to the scalp, yields 100mg— the optimal sample size for testing and confirmation. For EtG, additional testing, and panels exceeding ten, a 150mg sample is suggested. We advise using a jeweler’s scale for weighing the sample. Should scalp hair be inaccessible, body hair of a similar amount may be used. References to head hair imply scalp hair exclusively; in this context, body hair encompasses all other hair types, such as facial or axillary hair.

Process Overview

The drug testing laboratory process consists of four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning represents the initial step of introducing a sample into a lab’s processing system, confirming the sample is properly sealed and shipped, assigning a LAN (Laboratory Accessioning Number), and finalizing any data entry missing from an electronic chain of custody system.

The Screening phase offers a preliminary check for drugs. While it efficiently rules out drug use in most cases, a positive initial screen must undergo confirmation to be legally valid. Presumptively positive samples from Screening require further confirmation.

For samples identified as presumptively positive during Screening, additional hair is extracted from the original sample for the Extraction phase. In this phase, drugs are retrieved from the hair at much lower levels than other techniques, such as urine or oral fluid tests, highlighting the complexity of performing hair drug testing.

Any presumptive positive results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before Confirmation, all samples that tested positive initially undergo washing as necessary. The comprehensive laboratory process, from Accessioning through to Confirmation, is conducted under stringent review according to both the CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Unlike urine tests, hair tests reveal drug use for up to 90 days.
• Hard to manipulate: Cheating a hair drug test is notably challenging, ensuring precise outcomes.
• Tracks historical usage: Displays a timeline of drug consumption rather than just recent usage.

Limitations:

• Not suitable for recent consumption: Drugs become traceable in hair after about 5-7 days.
• Expensive: Hair drug testing generally incurs higher costs than other testing methods.
• Result variations: Elements such as hair color and individual hair growth rates can affect drug metabolite concentrations in hair.

Note: Although often termed "hair follicle tests", this test evaluates the hair strand itself, not the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Huntsville, WA, the benefits of hair follicle testing outweigh those of urine evaluations. Hair samples provide 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.
