Hair Follicle Drug Testing - Spring Ridge, MD

What it is, How it works

Hair testing is increasingly recognized as an effective method for detecting drug and alcohol usage. Hair captures a long-term record of drugs and alcohol by embedding biomarkers within the fibers of the growing strand. When taken near the scalp, it can offer approximately a three-month detection period for substances. Hair is easy to collect, relatively tough to tamper with, and simple to transport.

A sample of about 1.5 inches, consisting of roughly 200 strands (comparable to the thickness of a #2 pencil) near the scalp, provides around 100mg of hair, the preferred quantity for screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg is advised. We suggest using a jeweler’s scale for weighing. If scalp hair is not available, an equivalent amount of body hair can be used. By head hair, we mean scalp hair exclusively. Body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

There are four primary stages in processing a drug test result in the lab: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the sample's initial processing into the lab's system. This step confirms the sample's proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data input not included in an electronic chain of custody system.

Screening is a preliminary check for abuse substances. While cost-effective for ruling out positive drug use in most samples, a positive screen requires confirmation to be valid in court. Samples testing presumptively positive during Screening need further confirmation.

When a sample tests presumptively positive in Screening, additional hair is extracted from the original sample and prepared for Extraction. At this stage, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology.

Confirmation of a positive screening outcome is done using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a wash before confirmation as required. The full laboratory procedure from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests with a shorter detection span.
• Hard to falsify: Hair drug tests are challenging to cheat, enhancing result reliability.
• Shows historical trends: Provides insight into drug usage over time, rather than recent consumption only.

Limitations:

• Inability to detect recent consumption: It requires approximately 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests generally incur higher costs compared to alternative drug testing approaches.
• Result variations: Drug metabolite concentrations in hair can vary due to factors like hair color and individual hair growth differences.

Note: Although commonly known as "hair follicle tests", the analysis targets 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.
