Hair Follicle Drug Testing - Tilghman Island, MD

What it is, How it works

Hair testing is now viewed as a robust means for identifying drug and alcohol consumption. Hair retains a comprehensive record of alcohol and other substances by embedding biomarkers within the strands as they grow. When taken near the scalp, hair can offer a detection window for substances spanning up to about 3 months. It is straightforward to collect, fairly resilient to tampering, and simple to transport.

A sample measuring 1.5 inches, consisting of around 200 hairs (approximate thickness of a #2 pencil), when taken closest to the scalp, yields about 100 mg, which is the preferred sample size for screening and confirmation. For EtG, additional tests, and tests exceeding 10 panels, 150 mg of the sample is advisable. It is suggested to weigh the sample using a jeweler’s scale. If scalp hair is scarce, equivalent body hair can be utilized. The term "head hair" exclusively refers to scalp hair, while "body hair" includes all other hair types (like facial or axillary).

Process Overview

The drug test laboratory process consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where a sample is incorporated into the lab’s system. This step ensures the sample was correctly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any missing information outside an electronic chain of custody mechanism.

Screening provides a preliminary general check for drug abuse. Although cost-effective for excluding drug use in the bulk of samples, a confirmed screen is needed for legal acceptability. Samples testing positive in Screening require subsequent confirmation.

In cases where Screening suggests positivity, additional hair is retrieved from the original sample for Extraction. During Extraction, drugs are segregated from the hair at significantly lower concentrations than alternate methods (such as urine or oral fluid), making hair drug analysis the most challenging to execute.

Positive screen results are validated via GC/MS, GC/MS/MS, or LC/MS/MS. Samples appearing presumptively positive are cleansed prior to confirmation as necessary. The entire procedure from Accessioning to Confirmation is scrutinized under the auspices of both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Prolonged detection span: Hair tests reveal substance usage up to 90 days, unlike urine tests with a shorter detection period.
• Resistance to manipulation: Fraudulent hair drug tests are difficult to achieve, enhancing result accuracy.
• Shows usage trends: It provides insights into drug use patterns over time, not merely recent ingestion.

Limitations:

• Inability to identify recent use: Drugs only become visible in hair approximately 5-7 days post-consumption.
• Expense: Hair drug tests tend to be pricier compared to other drug testing techniques.
• Result variability: Elements such as hair color and personal hair growth rates can impact drug metabolite concentrations in the hair.

Note: Though frequently called "hair follicle tests," the assessment targets the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why choose hair follicle testing over urine tests in Tilghman Island, MD? Hair tests offer superior drug detection, known for their precision in identifying long-term substance use compared to urine tests. With an extended detection period, hair tests present a more comprehensive view of an individual's drug history.

While urine tests often miss long-term patterns, hair testing reliably reports consistent use, aiding employers and agencies in thorough evaluations. Hair tests win in accuracy and reliability, ensuring greater confidence in 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.
