Hair Follicle Drug Testing - Merrill, MI

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair records long-term alcohol and drug use by embedding biomarkers within the fibres of the developing hair strand. When clipped near the scalp, hair reveals up to roughly a 3-month detection span for alcohol and drugs. It's easy to gather, hard to alter, and straightforward to send.

An inch and a half sample containing about 200 hairs (roughly the width of a #2 pencil) nearest to the scalp weighs about 100mg, the perfect quantity for analysis and confirmation. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advisable. Utilizing a jeweler's scale to measure the specimen is recommended. If scalp hair is absent, an equivalent portion of body hair is viable. References to head hair denote strictly scalp hair. Body hair relates to every other type (facial, axillary, etc.).

Process Overview

The lab handling of a drug test result is characterized by four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning concerns the initial intake of a sample into a laboratory's database. This step involves confirming that the sample was properly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and filling in any extra data gaps absent from an electronic chain of custody system.

Screening offers a preliminary quick assessment for illicit drug presence. While screening is a budget-friendly means to dismiss drug use in most samples, a positive preliminary result requires confirmation to stand in legal proceedings. All samples flagged as presumptively positive in Screening necessitate further confirmation.

If Screening suggests a positive outcome, additional hair is extracted from the primary sample and set for Extraction. Drugs are retrieved from hair at significantly lower concentrations than other methods (such as urine or oral fluid), rendering hair drug screening exceptionally challenging to execute.

Confirmation for any positive screen results is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptively positive are cleansed before confirmation, as necessary. The full laboratory sequence from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 credential standards.

Advantages of hair drug testing:

• Extended detection span: Hair drug evaluations can reveal drug consumption for up to 90 days, unlike urine tests with a shorter detection timeline.
• Hard to evade: Evading a hair drug test is very challenging, thus offering more precise results.
• Historical insight: It reflects a drug use pattern over time instead of merely recent use.

Limitations:

• Cannot identify recent usage: Drugs require about 5-7 days to become noticeable in hair.
• Expense: Hair drug evaluations typically cost more than other drug testing techniques.
• Result disparities: Elements like hair pigmentation and individual hair growth variations can influence drug metabolite levels in hair.

Note: Although frequently termed as "hair follicle tests", this assessment analyzes the hair strand, not the root under the scalp.

Why Hair Follicle Testing Beats Urine Testing

Choosing hair follicle testing over traditional urine tests in Merrill, MI offers clear advantages. Hair testing provides superior detection accuracy and reliability. Unlike urine tests, which have a shorter detection window, hair follicle tests can identify substance use over a prolonged period, giving employers a clearer substance use history of an individual.

Extended Detection Window

In Merrill, MI, the extended detection window of hair follicle testing provides a broader view of drug usage. While urine tests are limited in their scope, hair testing can identify substance use over up to 90 days. This long-term detection offers employers comprehensive insight into an individual’s substance history, fostering informed decisions.

Tamper-Resistant Testing Method

Hair follicle testing in Merrill, MI is a tamper-resistant solution for drug testing. Unlike urine samples, which can be more easily adulterated, hair samples minimize the risk of contamination or manipulation. This provides results that are both trustworthy and difficult to dispute, ensuring test integrity.

Convenient Nationwide Locations

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.
