Hair analysis has emerged as a robust method for identifying the use of drugs and alcohol. The hair captures a prolonged timeline of drug consumption, including alcohol, by embedding biomarkers in its growing strand structure. When sourced near the scalp, this method can reveal drug or alcohol use for up to three months. The collection process for hair is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch section consisting of roughly 200 hair strands (about the thickness of a #2 pencil) from near the scalp can yield 100mg of hair, which is optimal for initial and confirmatory testing. For EtG, additional testing, or more than 10-panel tests, a 150mg sample is suggested. It is advisable to weigh the hair sample using a jeweler’s scale. If head hair is not an option, an equivalent quantity of body hair might be used. The term "head hair" specifically denotes scalp hair, whereas "body hair" covers all other types (facial, axillary, etc.).
Process Overview
The primary steps in processing a drug test result in a lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the step where a sample is first integrated into the lab’s system. This step involves confirming that the sample is correctly sealed and shipped, assigning it a random LAB (Laboratory Accessioning Number), and completing any further data entries not fulfilled by an electronic chain of custody system.
Screening is a preliminary review for signs of drug use. Although Screening is a cost-effective option for excluding drug usage in most samples, any positive findings must be confirmed for admissibility in legal settings. Presumptively positive samples in Screening require further Confirmation.
For samples that are presumptively positive at the Screening level, more hair is extracted from the initial batch for Extraction. Here, drugs are extracted from the hair at notably lower concentrations compared to other methods like urine or oral fluid, making hair drug screening particularly challenging to execute.
The Confirmation of any screening positives is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing as necessary before confirmation. The complete lab process, from Accessioning to Confirmation, is subject to review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly called "hair follicle tests", the analysis is conducted on the hair strands, not the follicles beneath the scalp.
Why is hair follicle testing superior to urine testing in Nokomis, FL? Primarily, hair tests offer a longer detection window, ensuring more comprehensive insight into drug use patterns. Compared to traditional urine tests, which detect recent use, hair tests are more reliable and harder to manipulate, reducing risks of improper results.
Employers in Nokomis, FL benefit from the extended detection window of hair follicle testing. Capturing drug use history up to 90 days, it provides detailed information on an individual's substance use, giving a broader picture compared to short-term detection methods, thereby aiding in better-informed employment decisions.
In Nokomis, FL, the tamper-resistant nature of hair follicle testing offers a significant advantage over other methods. The difficulty in tampering with hair samples ensures the authenticity of results, providing employers and legal entities with the assurance of accuracy and validity in drug testing outcomes.
The presence of convenient testing locations nationwide, including Nokomis, FL, ensures hassle-free access to drug testing services. With numerous local centers, obtaining a test is quick and straightforward, facilitating prompt and efficient service for both individuals and companies.
In Nokomis, FL, the process of ordering and completing a hair follicle test is designed to be simple and confidential. From placing the order to receiving results, the procedure ensures privacy and ease, addressing concerns regarding confidentiality and providing assurance to test-takers.
In terms of cost efficiency, Nokomis, FL offers affordable pricing and swift service for hair follicle testing. Companies of all sizes benefit from competitive rates and rapid turnaround times, guaranteeing excellent value while maintaining the integrity and reliability of testing results.
In Nokomis, FL, hair follicle drug tests provide fast, accurate, and reliable results, making them a top choice for detecting substance use. These tests deliver precise outcomes swiftly, allowing for quick decision-making. Hair tests ensure high accuracy levels in identifying past drug use, contributing to their popularity.
