Hair Follicle Drug Testing - Monroe City, MO

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair serves as a record keeper of alcohol and drug markers by embedding them within the strands' fibers. When sourced near the scalp, hair offers a detection window of approximately three months for alcohol and drugs. Hair is easy to collect, relatively resistant to tampering, and simple to transport.

A 1.5-inch section consisting of roughly 200 hair strands (akin to the thickness of a #2 pencil) closest to the scalp supplies 100mg of hair, which is the standard amount for analysis and verification. For EtG, supplementary tests, and tests exceeding 10 panels, a 150mg hair sample is suggested. It is advisable to weigh the hair sample using a jeweler’s scale. If head hair isn’t obtainable, an equivalent quantity of body hair can be sourced. When we mention head hair, it specifically refers to scalp hair. Body hair encompasses all other types (including facial, axillary, etc.).

Process Overview

The primary steps in the laboratory evaluation of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the initial handling of a sample within a lab's system. This involves checking that the sample was sealed and shipped correctly, generating a random LAN (Laboratory Accessioning Number), and completing any manual data input not handled by an electronic chain of custody system.

Screening incorporates an initial rapid assessment for substance abuse. Although Screening offers a cost-efficient method to negate drug use in most samples, a screen result that is positive requires confirmation for legal credibility. Any sample with a presumptively positive result during Screening demands additional confirmation.

If Screening suggests positivity, more hair is extracted from the initial sample for further Examination. During this phase, substances are extracted from hair at much lower concentrations than other techniques (such as urine or oral fluid), which explains why hair drug assessment is the most complex method to conduct.

Confirming any positive Screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumptively positive undergo washing before confirmation as needed. The comprehensive lab process from Accessioning to Confirmation is assessed following the CAP (College of American Pathologists) Hair criteria and aligned to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can detect substance use for up to 90 days, unlike urine tests, which have a shorter detection timeframe.
• Hard to falsify: Counterfeiting results on a hair drug test is very challenging, making the findings more reliable.
• Delivers historical insights: It can reveal a usage trend over time, rather than just recent consumption.

Limitations:

• Cannot identify recent consumption: It takes about 5-7 days for hair to register drug traces.
• Expense: Hair drug assessments often cost more than other testing methods.
• Result variability: Factors such as hair color and personal hair growth differences can influence the concentration of drug residues in the hair.

Note: Although frequently termed "hair follicle tests", the exam actually analyzes the hair strand, not the underlying hair follicle beneath the scalp

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.
