Hair Follicle Drug Testing - East Sierra, CA

What it is, How it works

Hair analysis is now regarded as an effective method for identifying drug and alcohol intake. Hair captures a prolonged record of alcohol and drug use by encapsulating biomarkers within the hair's growing strands. When gathered near the scalp, hair can provide a detection window for drugs and alcohol of up to around 3 months. Hair is easy to gather, challenging to tamper with, and simple to transport.

A 1.5-inch segment of approximately 200 hairs (comparable in size to a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal sample size for both screening and confirmation. For EtG, supplementary tests, or when requiring tests beyond 10 panels, a 150mg sample is advised. We suggest weighing the sample on a jeweler's scale. If scalp hair isn't available, an equivalent amount of body hair can be used. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other types (like facial hair, axillary hair, etc.).

Process Overview

The four principal stages in the laboratory processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the first phase of integrating a specimen into a laboratory's system. This process ensures the sample was properly sealed and transported, assigns a random Laboratory Accessioning Number (LAN), and completes any further data entry required beyond what an electronic chain of custody system provides.

Screening involves an initial, rapid assessment for substances of abuse. While Screening offers a cost-effective means to eliminate drug use in most samples, any positive finding must be validated to be accountable in a legal setting. Samples that appear positive in Screening need further confirmation.

If a sample tests positive in the Screening phase, additional hair is extracted from the original specimen for preparation in Extraction. This stage extracts drugs from hair at concentrations significantly lower than other methods (such as urine or oral fluid), making hair drug screening one of the most challenging methodologies.

Confirmation of any positive screening findings is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples indicating a positive result in Screening are washed before confirmation as necessary. The laboratory process from Accessioning through Confirmation undergoes review in accordance with both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests which have a shorter detection span.
• Hard to manipulate: It's extremely challenging to interfere with a hair drug test, enhancing result accuracy.
• Provides usage history: It can illustrate a usage pattern over time rather than only recent use.

Limitations:

• Cannot identify recent usage: Drugs are typically detectable in hair after about 5-7 days.
• Expense: Hair drug tests are often pricier compared to other drug testing methods.
• Result variability: Factors such as hair color and individual hair growth differences can influence how drug metabolites concentrate in the hair.

Note: Although often referred to as "hair follicle tests," the analysis is performed on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In East Sierra, CA, hair follicle testing offers a strategic advantage over traditional urine tests. Unmatched Detection Accuracy makes it the preferred choice for those seeking reliable results. Unlike urine tests that, at times, fail to detect long-term substance use, hair testing delivers consistent and dependable outcomes, reducing the risk of misleading results and ensuring that individuals are accurately screened for potential drug use.

Extended Detection Window

The hair follicle test in East Sierra, CA, provides an Extended Detection Window, capable of identifying drug use for an extensive duration—up to 90 days. This thorough evaluation grants employers a substantial view into an individual’s substance use over time, rather than offering a limited perspective. Such a comprehensive analysis is particularly vital for pre-employment screenings, ensuring a drug-free workplace by understanding the applicant's or employee's substance history.

Tamper-Resistant Testing Method

Hair follicle tests conducted in East Sierra, CA, are integral due to their inherently Tamper-Resistant quality. Unlike other testing methods that may be susceptible to tampering or manipulation, the hair follicle is a reliable source that significantly minimizes the risk of adulteration. This reliability enhances the trustworthiness of the results, ensuring that the outcomes are beyond question, which is crucial for maintaining informed and fair evaluation policies.

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.
