Hair Follicle Drug Testing - Loma Linda, CA

What it is, How it works

Hair analysis is now recognized as an effective method for identifying substance use, including drugs and alcohol. Hair captures a long-term record of these substances by storing biomarkers within the fibers of the growing strands. Collecting hair close to the scalp allows for a detection window of up to three months for alcohol and drugs. The collection of hair is straightforward, relatively resistant to tampering, and easy to transport.

A sample of 1.5 inches consisting of about 200 hair strands (roughly the width of a #2 pencil) nearest to the scalp yields 100mg of hair, perfect for both screening and verifying. For EtG, additional tests, or screenings beyond 10 panels, a 150mg sample is advised. We advise using a jeweler’s scale for weighing the sample. If scalp hair is unavailable, a comparable amount of body hair may be used. When mentioning head hair, we refer exclusively to scalp hair. Other body hairs include facial, axillary, and more.

Process Overview

The drug test lab process involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves integrating a sample into the laboratory system. This step ensures the sample was properly sealed and shipped, a random LAN (Laboratory Accessioning Number) is assigned, and any supplementary data not included in an electronic chain of custody system is completed.

Screening performs an initial review for drugs of abuse. Although Screening is a cost-effective method to exclude drug use in most samples, a positive result needs confirmation to be usable in legal contexts. Samples presumed positive in Screening must undergo secondary confirmation.

If a sample shows presumptive positivity in Screening, additional hair is extracted from the initial sample for the Extraction process. In this stage, drugs are extracted from hair at concentrations much lower than those in other methods (e.g., urine or oral fluid), which accounts for the complexity of hair drug screening.

Confirmation of any positive screen result is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptively positive samples undergo washing before confirmation as necessary. The comprehensive laboratory process from Accessioning through Confirmation meets both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, whereas urine tests offer a shorter timeframe.
• Difficult to tamper: Tampering with a hair drug test is challenging, thereby enhancing result accuracy.
• Provides historical patterns: It can show a drug usage pattern over time, not just recent consumption.

Limitations:

• Inability to detect recent use: It takes around 5-7 days for drugs to become recognizable in hair.
• Expense: Hair drug tests tend to be more costly than other testing techniques.
• Result variations: Elements like hair color and individual hair growth differences can impact drug metabolite concentration in hair.

Note: Commonly termed "hair follicle tests", the analysis actually evaluates the hair strand, not the follicle under the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing eclipses urine testing with superior detection accuracy in Loma Linda, CA. With a longer lookback window, it captures a more complete substance use history, making it harder to evade. The certainty of results gives peace of mind unmatched by standard urine tests.

Employers and legal professionals opt for hair tests due to their robustness and reliability. Unlike urine tests, which can be influenced by recent activities, hair tests provide a comprehensive view of an individual's long-term drug use patterns.

Extended Detection Window

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.
