Hair Follicle Drug Testing - Wilmington, MA

What it is, How it works

Hair testing is regarded as an effective method for detecting drug and alcohol consumption. Hair captures a long-term record of substances by embedding biomarkers within the fibers of the growing strand. When hair is collected close to the scalp, it can indicate substance use history up to roughly a 3-month period. Hair sample collection is straightforward, challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches, consisting of about 200 strands (comparable to the thickness of a #2 pencil) near the scalp, provides approximately 100mg of hair, the preferred amount for initial screening and verification. For tests such as EtG, add-ons, and those exceeding 10 panels, a specimen of 150mg is advised. We suggest using a jeweler’s scale for accurate specimen measurement. In the absence of scalp hair, an equivalent amount of body hair is acceptable. References to head hair specifically mean scalp hair. Body hair encompasses all other hair areas (e.g., facial, axillary).

Process Overview

The laboratory processing of a drug test involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase, where a sample is processed into the laboratory’s documentation system. This process confirms the proper sealing and transportation of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any needed data input not covered by an electronic chain of custody system.

Screening is a preliminary, efficient check for drug presence. Though Screening is cost-effective for excluding drug use in most samples, a confirmation is necessary for court-admissible evidence. Samples with a presumptive positive in Screening require secondary confirmation.

With a presumptive positive result during Screening, additional hair from the original sample is set aside for Extraction. Drugs are extracted from hair at a lower concentration than other samples like urine or oral fluid, underscoring hair testing’s complexity.

Positive screening confirmations are carried out using techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing prior to confirmation if needed. The full laboratory procedure, from Accessioning to Confirmation, adheres to both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extensive detection period: Hair drug testing can trace drug use up to 90 days, unlike urine tests with shorter detection spans.
• Low risk of tampering: Cheating on a hair drug test is notably difficult, ensuring more reliable results.
• Historical usage patterns: Offers insights into drug consumption over time rather than only recent use.

Limitations:

• No recent use detection: Drugs take around 5-7 days to become detectable in hair.
• Higher expense: Hair drug tests tend to be pricier than other testing methods.
• Result variations: Factors like hair color and unique growth differences can influence drug metabolite concentrations in hair.

Note: Commonly misnamed as "hair follicle tests", it is the hair strand that undergoes analysis, not the follicle itself under 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. 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.
