Hair Follicle Drug Testing - Le Roy, MI

What it is, How it works

Hair testing is recognized as an effective technique for identifying drug and alcohol use. Hair offers a prolonged record of substances by capturing biomarkers within the fibers of the growing strand. When obtained near the scalp, hair can present a detection period of up to about 3 months for alcohol and other drugs. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.

A sample measuring 1.5 inches, composed of approximately 200 hair strands (around the thickness of a #2 pencil) nearest to the scalp, will yield 100mg, which is ideal for screening and confirmation. For EtG, add-ons, and tests beyond 10 panels, 150mg of hair is advisable. It's best to weigh the specimen using a jeweler’s scale. If scalp hair isn't available, an equivalent quantity of body hair may be gathered. When mentioning head hair, we're specifically indicating scalp hair. Body hair represents all other hair varieties (facial, axillary, etc.).

Process Overview

The four primary stages in the lab analysis of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

The Accessioning phase entails the initial integration of a sample into a laboratory’s system. This step ensures the sample was sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and finalizes any supplementary data entry not covered by an electronic chain of custody system.

Screening is a preliminary assessment for the presence of drugs. While a cost-efficient method to exclude drug use in most samples, a positive screen necessitates confirmation for court acceptance. Samples indicating a presumptive positive in Screening require additional confirmation.

For samples that test presumptive positive during Screening, additional hair is extracted from the initial specimen for preparation in the Extraction stage. Here, drugs are logged from hair at significantly lower concentrations compared to other methodologies (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing prior to confirmation as required. The comprehensive lab process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests can reveal drug consumption over a 90-day span, unlike urine tests which have shorter detection periods.
• Hard to manipulate: Cheating a hair drug test is quite challenging, resulting in more precise outcomes.
• Historical insight: It provides a pattern of drug use over time, not solely recent use.

Limitations:

• Lack of immediate detection: It requires about 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests generally cost more than other testing methods.
• Result deviations: Variables such as hair color and individual hair growth differences can impact metabolite concentration in hair.

Note: Although often termed "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why does hair follicle testing surpass urine tests in Le Roy, MI? The benefits of hair testing include its superior detection acuity and certified reliability. Hair tests offer a more extensive window for identifying drug usage, making them more effective and difficult to manipulate compared to urine tests.

Employers and professionals often prefer hair testing due to these advantages. While urine tests offer accuracy within shorter periods, hair follicle tests provide an all-encompassing review over longer durations, thus offering more thorough insights.

Extended Detection Window

In Le Roy, MI, hair follicle tests can detect drug use for up to 90 days, offering a comprehensive view of a person’s substance history. This extended detection window makes the method valuable for employers seeking detailed information on an applicant or current employee’s drug usage over extended durations.

Tamper-Resistant Testing Method

Hair follicle testing in Le Roy, MI, offers a tamper-resistant solution to drug testing. Unlike other methods, it minimizes sample manipulation risks, ensuring dependable and indisputable results. This integrity fortifies the trust in the testing process among both employers and individuals.

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.
