Hair Follicle Drug Testing - Soulsbyville, CA

What it is, How it works

Hair analysis is increasingly perceived as an effective method for detecting drug and alcohol consumption. Hair retains a prolonged record of substance use by embedding biomarkers within the fibers as the hair strand develops. When samples are taken close to the scalp, they can offer nearly a 3-month detection period for substances. Hair collection is straightforward, somewhat resistant to tampering, and easy to transport.

A sample measuring 1.5 inches with about 200 hair strands (approximately the thickness of a #2 pencil) near the scalp can provide 100mg of hair, which is the optimal quantity for both screening and further verification. For EtG, additional panels, or testing beyond 10 panels, a sample of 150mg is advised. We suggest measuring the sample on a jeweler’s scale. If scalp hair is not available, a similar quantity of body hair can be used. When mentioning head hair, we specifically mean hair from the scalp. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory evaluation of a drug testing result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially processed into the lab’s system. This process includes checking that the sample was correctly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any data entries not completed via an electronic chain of custody process.

Screening consists of a preliminary rapid assessment for potential drug misuse. While this provides an economical way to exclude drug use in most cases, any positive screen must be confirmed to be used in legal proceedings. Samples that test presumptively positive during Screening require subsequent confirmation.

Should a sample test presumptively positive in the Screening phase, additional hair is extracted from the initial sample for the Extraction stage. Here, drugs are removed from the hair at a much lower concentration than in other methods (such as urine or saliva), which is why hair drug analysis is considered the most complex technique to perform.

Confirmation of a positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples are cleansed before confirmation if necessary. The complete lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can identify drug usage for up to 90 days, offering a longer window than urine tests.
• Difficult to evade: Cheating such a test is challenging, enhancing the reliability of results.
• Tracks usage trends: It provides insights into drug use patterns over time, not solely recent use.

Limitations:

• Not ideal for recent use detection: Drugs typically take 5-7 days to become traceable in hair.
• Expense: Hair testing is often pricier compared to other drug testing approaches.
• Result variability: Factors like hair color and individual hair growth can influence drug metabolite concentration in hair.

Note: Despite being called "hair follicle tests", the analysis is conducted on the hair strand, not the follicle 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.
