Hair Follicle Drug Testing - Max, MN

What it is, How it works

Hair testing is recognized as an effective means for detecting the use of drugs and alcohol. Hair strands provide an extended record of alcohol and drug exposure by capturing biomarkers within the fibers of growing hair. When hair is taken near the scalp, it can offer roughly a 90-day detection period for alcohol and drugs. Hair is easy to collect, challenging to tamper with, and straightforward to transport.

A sample measuring 1.5 inches, comprising roughly 200 strands of hair (comparable in thickness to a #2 pencil) nearest to the scalp, yields 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, 150mg of specimen is advised. It's advisable to assess the specimen’s weight using a jeweler’s scale. If scalp hair is inaccessible, an equivalent quantity of body hair can be gathered. References to head hair pertain solely to scalp hair. Body hair includes all other types of hair (e.g., facial, axillary).

Process Overview

The lab testing process for drug testing comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a sample within a lab's framework. This step verifies correct sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary data entry absent from an electronic chain of custody system.

Screening is a preliminary rapid assessment for drugs of abuse. While Screening is an economical method to exclude drug usage in most samples, a positive screen must be confirmed for court admissibility. Samples with presumptive positives in Screening necessitate secondary confirmation.

If Screening yields a presumptive positive sample, additional hair is extracted from the initial specimen for preparation in Extraction. During Extraction, drugs are isolated from hair at concentrations much lower than those in other methods (e.g., urine or oral fluid), making hair drug screening the most complex methodology to execute.

Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation as required. The laboratory process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair accreditation and aligned with ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, unlike urine tests which have a shorter detection span.
• Hard to manipulate: Cheating on a hair drug test is notably tough, enhancing result accuracy.
• Reveals usage patterns: Provides a trend of drug use over time, rather than immediate usage.

Limitations:

• Incapable of detecting recent use: Drugs typically become detectable in hair after 5-7 days.
• Expense: Hair drug tests tend to be costlier than alternative testing methods.
• Result disparities: Elements like hair color and individual hair growth differences can impact drug metabolite concentrations in hair.

Note: Commonly known as "hair follicle tests", these tests actually analyze the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

When comparing drug testing methods in Max, MN, hair follicle testing typically outperforms urine testing. The benefits of hair testing are evident as they deliver a higher detection accuracy.

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.
