Hair Follicle Drug Testing - Maquoketa, IA

What it is, How it works

The utilization of hair testing has gained recognition as an effective means for identifying drug and alcohol consumption. Hair functions as a repository, capturing biomarkers within its fibers, thereby offering a prolonged timeline of alcohol and drug usage. Collected near the scalp, hair can provide a detection timeframe of approximately three months for alcohol and drugs. Collection is straightforward, tampering is relatively challenging, and shipping is convenient.

To obtain 100mg of hair, a sample measuring 1.5 inches with approximately 200 strands (similar in size to a #2 pencil) should be collected near the scalp, considered an ideal specimen for both screening and confirmation. For tests involving EtG, additional substances, or panels exceeding 10, a specimen of 150mg is advisable. Utilizing a jeweler's scale is recommended for weighing the sample. Should scalp hair be unavailable, an equivalent amount of body hair may be used. References to head hair specifically denote scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The key stages in processing a drug test result within a laboratory are Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial processing into the laboratory's system. This step ensures the sample was appropriately sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and completes any further data input absent in an electronic chain of custody system.

Screening constitutes an initial cursory examination for substance abuse. While cost-effective for dismissing drug use in most samples, a positive Screening result necessitates confirmation for legal admissibility. Any samples yielding a presumptive positive result in Screening must undergo a secondary confirmation.

In instances of presumptive positivity in Screening, additional hair is extracted from the original specimen for Extraction. This stage involves drug extraction from hair, which occurs at a lower concentration compared to other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.

Confirmation of any positive Screening outcome is carried out utilizing GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation if needed. The comprehensive process from Accessioning to Confirmation receives scrutiny under the CAP (College of American Pathologists) Hair designation and accreditation in compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Capable of identifying drug use up to 90 days, unlike urine tests with a shorter detection span.
• Resistance to fraud: Hair drug tests resist cheating, enhancing result validity.
• Offers historical insight: Provides a pattern of drug use over time, beyond immediate consumption.

Limitations:

• Inability to detect recent consumption: Drugs become detectable in hair roughly 5-7 days post-use.
• Expense: Hair drug tests usually incur higher costs compared to other testing methods.
• Result variability: Factors like hair color and individual hair growth rates can influence metabolite concentrations in hair.

Note: While often termed as "hair follicle tests", the analysis is conducted on the hair strand, not the 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.
