Hair Follicle Drug Testing - Valley City, IL

What it is, How it works

Hair analyses are acknowledged as an effective means for identifying drug and alcohol use. By capturing biomarkers within the fibers of the hair as it grows, hair retains a record of drug and alcohol exposure. A sample taken near the scalp can detect substances for up to about three months. The collection process is straightforward, with hair being tough to tamper with and convenient for shipping.

A sample consisting of 1.5 inches of approximately 200 hair strands (comparable to the girth of a #2 pencil) near the scalp equates to 100mg, which is the optimal amount for evaluation and confirmation. For extended testing such as EtG, add-ons, or panels exceeding 10, 150mg of the sample is suggested. It is advisable to weigh the sample with a jeweler's scale. If scalp hair is unavailable, an equivalent quantity of body hair is acceptable. References to head hair specifically pertain to scalp hair only, whereas body hair encompasses all other such as facial and axillary hair.

Process Overview

The key steps in lab processing of drug tests include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is where a sample is initially processed into the lab’s system. This step ensures the sample was properly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any further data entry that isn't covered by an electronic custody system.

Screening is an initial low-cost method to detect drug presence. Although effective for most samples, a positive screen must be validated for legal proceedings. Any samples with presumed positive screens need further confirmation.

Should a Screening phase suggest a positive result, additional hair from the sample is used for Extraction. Extraction involves isolating drugs from the hair, requiring much lower concentrations than other methods (such as urine or saliva), making hair screening notably challenging.

Confirmatory tests for any positive screenings are conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation, if necessary. Every phase of processing from Accessioning to Confirmation is subjected to inspection under CAP (College of American Pathologists) Hair designation and accreditation per ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can trace substance use back 90 days, unlike urine tests which cover a shorter span.
• Challenge to falsify: The reliability of hair tests is heightened as they are tough to fool.
• Reveals usage history: It can show drug use patterns over time, beyond merely recent usage.

Limitations:

• Not suitable for recent consumption: Detectability in hair takes about 5-7 days post-drug use.
• Expense: Hair tests generally cost more than alternate drug testing methods.
• Result variability: Variances such as hair color and individual growth rates might influence drug metabolite concentration in hair.

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

Why Hair Follicle Testing Beats Urine Testing

In Valley City, IL, hair follicle testing holds a notable advantage over traditional urine tests. With superior sensitivity, hair tests provide a wider detection scope and accurate results.

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.
