Hair Follicle Drug Testing - Wheaton, MD

What it is, How it works

Hair analysis is regarded as an effective method for identifying drug and alcohol consumption. Hair strands offer an extended timeline of alcohol and other substance exposure by encapsulating biomarkers within the fibers of the growing strand. When taken from near the scalp, hair can provide roughly a 3-month timeframe for detecting alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and convenient for transportation.

A hair sample of 1.5 inches from approximately 200 strands (similar in size to a #2 pencil) near the scalp yields 100mg, which is the optimal sample amount for both screening and confirmation. For EtG, additives, or tests exceeding 10 panels, a quantity of 150mg is advised. It's suggested to measure the sample using a jeweler's scale. If scalp hair is lacking, a comparable amount of body hair can be utilized. The term "head hair" specifically denotes scalp hair, whereas "body hair" refers to all additional hair types (e.g., facial, axillary).

Process Overview

The core stages in laboratory processing for a drug test result comprise Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into a lab’s system. This step involves confirming the sample was sealed and shipped correctly, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.

Screening entails a preliminary swift evaluation for drug abuse. While this step is an economical means to rule out drug usage in most samples, any positive result from Screening needs verification to be valid in legal settings. Samples indicating a presumptive positive in Screening necessitate a supplementary confirmation.

If Screening indicates a sample as presumptively positive, additional hair is extracted from the original sample for Extraction. During Extraction, drugs are isolated from the hair in significantly lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening the most challenging methodology to execute.

Confirmation of any positive results from screening is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive undergo washing before confirmation if necessary. The entire laboratory procedure from Accessioning through Confirmation is inspected under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug intake up to 90 days, unlike urine tests with a briefer detection span.
• Resistance to tampering: It is extremely challenging to deceive a hair drug test, resulting in more reliable outcomes.
• Historical usage profile: It offers a timeline of drug usage patterns, not solely recent consumption.

Limitations:

• Inability to detect recent use: Drug detectability in hair requires an approximate 5-7 day incubation period.
• Expense: Generally, hair drug tests are costlier than alternative drug testing approaches.
• Result variability: Influences such as hair color and personal differences in hair growth can impact drug metabolite concentrations in hair strands.

Note: Despite commonly being referred to as "hair follicle tests," these tests examine the hair strand rather than 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.
