Hair Follicle Drug Testing - Sainte Genevieve, MO

What it is, How it works

Hair analysis has been recognized as an effective instrument for identifying drug and alcohol consumption. Hair captures a long-term record of substance use by encapsulating biomarkers within the strands of hair as it grows. When sourced near the scalp, hair can reveal up to an estimated three-month detection period for alcohol and drugs. Collecting hair is straightforward, relatively resistant to tampering, and convenient for transport.

A sample measuring 1.5 inches, consisting of approximately 200 hair strands (similar in width to a #2 pencil) nearest to the scalp, yields 100mg of hair, which is the optimal quantity for screening and verification. For tests like EtG, add-ons, and those surpassing ten panels, a specimen amounting to 150mg is advisable. We suggest measuring the specimen with a jeweler’s scale. In the absence of scalp hair, a comparable volume of body hair can be used. When mentioning head hair, we are specifically referring to scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).

Process Overview

The laboratory procedure for processing drug test results consists of four essential steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a sample into the laboratory's system. This procedure includes ensuring the sample was properly sealed and shipped, assigning it a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.

Screening involves an initial rapid evaluation for potential drug misuse. Although Screening is a cost-efficient method to exclude drug usage in most samples, any positive screening needs confirmation for legal admissibility. Samples flagged as presumptively positive during Screening require further confirmation.

If a sample is deemed presumptively positive at the Screening stage, additional hair is extracted from the original specimen and prepared for Extraction. This phase involves extracting drugs from hair at concentrations markedly lower than other methods (e.g., urine or saliva), underscoring the complexity of hair drug screening.

Any positive screening outcome is confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are washed as necessary. The complete laboratory process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair certification and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection period: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests which have a reduced detection period.
• Challenging to manipulate: Altering the outcome of a hair drug test is challenging, ensuring more reliable results.
• Provides usage patterns: It offers insights into the pattern of drug use over a timeline, not limited to recent usage.

Limitations:

• Cannot identify recent use: Detection of drugs in hair takes approximately 5-7 days.
• Expense: Hair drug tests are typically costlier compared to other testing techniques.
• Result variations: Elements such as hair color and individual differences in hair growth can influence the drug metabolite levels in hair.

Note: Even though referred to as "hair follicle tests", it is the hair strand that is analyzed, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Sainte Genevieve, MO. While traditional urine tests are common, hair follicle tests offer superior detection accuracy and reliability. Hair testing detects drug use long after substances have left the bloodstream, unlike urine tests.

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.
