Hair Follicle Drug Testing - Glastonbury Center, CT

What it is, How it works

Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. The hair strand encapsulates long-term markers of substances by embedding them within its fibers as it grows. When taken near the scalp, hair offers a detection range for alcohol and drugs of nearly up to three months. It's effortless to collect, relatively tamper-resistant, and simple to transport.

A hair sample measuring 1.5 inches consisting of approximately 200 strands (around the diameter of a number two pencil) next to the scalp provides 100mg, the optimal quantity for both screening and verification. For EtG, additional tests, and evaluations exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale for weighing the sample. Should scalp hair be lacking, a comparable quantity of body hair can be utilized. When citing head hair, we specifically mean scalp hair. Body hair encompasses all other varieties (such as facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result comprises four principal steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial integration into a lab’s database. This step includes verifying the proper sealing and shipping of the sample, assigning it a random LAN (Laboratory Accessioning Number), and performing any supplemental data input absent from an electronic chain of custody protocol.

The Screening phase involves an initial rapid evaluation for controlled substances. Although Screening is a budget-friendly method to eliminate drug presence in the majority of samples, any positive indicator demands confirmation for legal admissibility. Samples considered presumptively positive in Screening necessitate a follow-up confirmation.

Should a sample indicate a presumptive positive during Screening, additional hair is taken from the original sample and readied for Extraction. This phase entails extracting drugs from hair at notably lower concentrations than alternative methods (such as urine or oral fluid), illustrating why hair drug testing stands as a challenging approach.

Positive screening outcomes undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples receive requisite washing prior to Confirmation. The complete laboratory procedure, from Accessioning to Confirmation, is scrutinized under CAP (College of American Pathologists) Hair category and accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection span: Hair tests identify drug use up to 90 days, while urine tests have limited detection spans.
• Hard to manipulate: Hair drug tests are challenging to deceive, ensuring greater accuracy.
• Chronological data: Provides a historical record of drug usage over time rather than capturing recent consumption alone.

Limitations:

• Inability to detect recent intake: Drugs appear in hair about 5-7 days post-consumption.
• Expense: Hair drug testing typically carries a higher cost relative to other testing modalities.
• Result variability: Elements like hair color and distinctive growth rates can influence the drug metabolite concentration in hair.

Note: Commonly termed as "hair follicle tests", the analysis is conducted on the hair strand instead of the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Glastonbury Center, CT, hair follicle testing surpasses traditional urine testing effortlessly.

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.
