Hair Follicle Drug Testing - Mountain View, CA

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drug use by embedding biomarkers within the strands of hair as they grow. When sampled near the scalp, hair can reveal a detection window of up to roughly three months for alcohol and drug substances. It is straightforward to gather hair samples, somewhat resistant to tampering, and convenient to transport.

A sample measuring 1.5 inches of around 200 hair strands (similar in thickness to a #2 pencil) closest to the scalp provides 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a specimen of 150mg is suggested. Using a jeweler’s scale is advisable for weighing the specimen. If scalp hair cannot be obtained, the same amount of body hair can be collected. In reference to head hair, only scalp hair is considered. Body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a sample within a lab's system. This process verifies that the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry not covered by an electronic chain of custody system.

Screening comprises an initial inspection for drugs of abuse. Although Screening is a cost-efficient method to eliminate drug usage from most samples, any positive screen necessitates confirmation to be legally admissible. Samples that screen positive require secondary confirmation.

If a sample yields a presumptive positive during Screening, additional hair is extracted from the initial sample and prepped for Extraction. During this phase, drugs are extracted from the hair at significantly lower concentrations than in other methods (such as urine or oral fluid), which accounts for the complexity of hair drug screening.

Confirmation for any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that yield presumptive positive results are cleansed before confirmation as needed. The entire laboratory procedure, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation and compliance with ISO/IEC 17025 standards.

Benefits of hair drug testing:

• Extended detection window: Hair drug tests can identify drug usage for up to 90 days, whereas urine tests have a shorter detection timeframe.
• Hard to deceive: Cheating a hair drug test is highly challenging, enhancing result accuracy.
• Historical usage data: It offers insights into drug usage patterns over time, not merely recent use.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair only after approximately 5-7 days.
• Expense: Hair drug tests generally incur higher costs than other testing methods.
• Result variations: Factors including hair color and individual hair growth rates may influence drug metabolite concentrations in hair.

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

Why Hair Follicle Testing Beats Urine Testing

In Mountain View, CA, hair follicle testing surpasses urine testing with its superior detection accuracy. While urine tests detect recent drug use, hair tests provide a more reliable and comprehensive assessment of one's substance 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.
