Hair Follicle Drug Testing - Zion, MO

What it is, How it works

Hair tests have emerged as an effective instrument for identifying drug and alcohol usage. Hair retains a longitudinal record of alcohol and drugs by embedding biomarkers within the strands' fibers. When taken near the scalp, hair testing offers up to roughly a three-month period of detection for substances. Collecting hair is straightforward, challenging to tamper with, and convenient for transit.

A sample measuring 1.5 inches comprising around 200 hair strands (comparable to a #2 pencil) taken nearest to the scalp provides 100mg of hair, the optimal amount for both screening and confirmation. For EtG, additional tests, or those exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale for weighing is recommended. Should scalp hair be unavailable, the same quantity of body hair may be used. When discussing head hair, we mean scalp hair specifically. Body hair encompasses all other types (facial, underarm, etc.).

Procedure Summary

The laboratory processing of drug test results comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary integration of a sample into the laboratory’s system. This process includes ensuring the sample was sealed and transported accurately, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody.

Screening acts as an introductory check for substances of abuse. Although Screening is a sensible way to indicate non-usage in most samples, any positive screen must be validated to be permissible in legal proceedings. Samples that test positively during Screening need a confirmatory follow-up.

If a sample registers positive in the Screening phase, additional hair is sourced from the original sample to prepare for Extraction. In this phase, drugs are drawn from hair at significantly reduced concentrations compared to other techniques (such as urine or oral fluid), which is why hair drug testing is notably complex.

Positive screening stand confirmed through methods like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed ahead of confirmation when necessary. The overall laboratory journey from Accessioning to Confirmation undergoes a thorough review in compliance with both the CAP (College of American Pathologists) Hair category and the ISO / IEC 17025 accreditation standards.

Benefits of hair drug testing:

• Extended detection window: Hair drug tests identify drug use for up to 90 days, unlike urine tests, which have a narrower detection period.
• Hard to tamper with: Cheating a hair drug test is extremely challenging, enhancing result accuracy.
• Provides usage history: It reveals a drug use trend over a time span, as opposed to only recent consumption.

Drawbacks:

• Unable to detect recent consumption: Drugs become detectable in hair after approximately 5-7 days.
• Higher expense: Hair drug tests generally cost more than alternative drug screening techniques.
• Result variability: Aspects like hair color and personal differences in hair growth may affect drug metabolite levels in hair.

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

Why Hair Follicle Testing Beats Urine Testing

The benefits of hair follicle tests over urine tests in Zion, MO are substantial. Hair tests can detect long-term usage far better than urine tests, which are primarily limited to recent consumption.

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.
