Hair Follicle Drug Testing - Gladstone, MI

What it is, How it works

Hair analysis has gained recognition as an effective method for identifying drug and alcohol usage. Hair captures a prolonged history of substance use by embedding biomarkers during hair growth. A sample taken near the scalp can offer an alcohol and drug detection period of approximately 3 months. Collecting hair is straightforward, has a low risk of tampering, and is simple to transport.

A 1.5-inch portion of about 200 hair strands (roughly the size of a #2 pencil) situated close to the scalp provides 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional tests, or examinations exceeding 10 panels, a specimen of 150mg is advised. We suggest using a jeweler's scale to measure the specimen. If scalp hair is scarce, an equal volume of body hair may be utilized. When mentioning head hair, we specifically mean scalp hair, while body hair encompasses all other types (such as facial and axillary hair).

Process Overview

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

Accessioning is the initial stage where a sample is brought into the laboratory system. This step ensures the sample was properly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry required outside of an electronic chain of custody system.

Screening is the preliminary rapid assessment for drug substances. While it is a cost-efficient way to eliminate most samples for drug use, positive findings must be confirmed to hold up in court. Presumptive positive samples from Screening necessitate an additional confirmation.

When a sample tests positive during the Screening phase, extra hair is extracted from the original sample for the Extraction process. Drugs are extracted at lower concentrations from hair than with other methods (e.g., urine or oral fluid), which is why hair drug screening is notably challenging to execute.

Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample undergoes a washing process before confirmation if necessary. The complete laboratory process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can recognize drug use for up to 90 days, unlike urine tests that have shorter detection periods.
• Challenging to manipulate: The difficulty in deceiving a hair drug test leads to more reliable results.
• Provides insight into drug habits: The test can reveal usage patterns over time, beyond just recent consumption.

Limitations:

• Cannot pinpoint recent use: It typically takes about 5-7 days for drugs to be evident in hair.
• Expense: Hair drug tests generally cost more than other drug testing techniques.
• Result variability: Factors like hair color and personal hair growth variations can influence the concentration of drug metabolites in the hair.

Note: Although often called "hair follicle tests", the test examines the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Gladstone, MI, surpasses urine testing by providing a longer and more reliable detection period for substance use. Whereas urine tests are limited to recent use, hair tests offer a clearer overview of an individual's history. This makes hair testing a superior choice for accurate results.

Extended Detection Window

Hair follicle testing offers a comprehensive view of drug use extending up to 90 days, unlike traditional methods. Employers in Gladstone, MI, benefit from this extended detection window, gaining insight into a candidate's substance history to make informed decisions.

Tamper-Resistant Testing Method

In Gladstone, MI, hair follicle tests stand out for their resilience against tampering. The method significantly reduces the risk of adulteration, ensuring that results remain reliable and beyond question. This makes hair tests the preferred choice for accuracy and trustworthiness.

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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
