Hair Follicle Drug Testing - Rancho San Diego, CA

What it is, How it works

Hair testing is considered a significant method for identifying drug and alcohol consumption. The hair traps biomarkers within its strands during growth, offering a long-term record of substance use. When collected from near the scalp, hair can reveal drug and alcohol use history for up to 3 months. The collection process for hair is straightforward, somewhat resistant to tampering, and convenient for shipping.

A sample of approximately 1.5 inches, containing about 200 hair strands (similar in width to a #2 pencil) from the scalp, provides 100mg of hair—ideal for both screening and confirmation testing. For EtG, additional checks, and tests exceeding 10 panels, 150mg of sample is suggested. It's advisable to use a jeweler’s scale for weighing the sample. If scalp hair isn't available, a similar quantity of body hair can be collected. "Head hair" refers strictly to scalp hair, while "body hair" encompasses all other types (including facial, axillary, etc.).

Process Overview

Lab processing of a drug test result includes four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is about entering a sample into a lab’s system, ensuring the sample's proper sealing and shipment, assigning a LAN (Laboratory Accessioning Number), and completing necessary data entry not covered by an electronic chain of custody system.

Screening performs a quick, preliminary test for drug presence. It's a cost-efficient strategy to rule out drug use in most samples; however, a positive screening outcome requires confirmation to be valid for legal proceedings. Samples that test presumptively positive during Screening must undergo secondary confirmation.

For any presumptive positive in Screening, additional hair is extracted from the original sample and prepared for Extraction. Drugs in hair are extracted at lower concentrations compared to other methods (such as urine or oral fluid), making hair drug testing the most complex methodology.

Confirmation for any positive Screening result employs GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples marked as presumptive positives are cleaned as necessary. The complete lab process, from Accessioning to Confirmation, is audited under the CAP (College of American Pathologists) Hair designation and according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can detect drugs for as long as 90 days, superior to urine tests with shorter detection spans.
• Challenge to falsify: Hair drug tests are hard to manipulate, enhancing result integrity.
• Historical insights: They offer a drug use pattern over time, not just recent consumption.

Limitations:

• Lacks immediate use detection: Drugs only become detectable in hair after about 5-7 days.
• Higher cost: Hair drug tests tend to be pricier compared to other methods.
• Result variability: Factors like hair color and personal hair growth rhythms can impact drug metabolite concentrations.

Note: The term "hair follicle tests" is often misused as the test analyzes the strand rather than 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.
