Hair Follicle Drug Testing - Piney Point, MD

What it is, How it works

The analysis of hair for drug and alcohol use has emerged as an effective method. Hair captures a historical record of substance use by embedding biomarkers within the hair's fibers as it grows. Sampling hair near the scalp can reveal alcohol and drug consumption over roughly a 90-day period. The collection process is straightforward, though tampering is challenging, and transport is simple.

A snippet of 1.5 inches, equivalent to 200 strands (the thickness of a #2 pencil) nearest to the scalp, yields 100mg, the optimal sample size for both screening and confirmation. For EtG, extended tests, or panels exceeding 10, a 150mg sample is advised. Verification of specimen weight is best done with a jeweler’s scale. In the absence of scalp hair, body hair of equal quantity can be collected. Reference to head hair means scalp hair exclusively, while body hair encompasses facial, axillary, and all other hairs.

Process Overview

The laboratory analysis process comprises four major stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary stage wherein the sample is integrated into the lab system. It includes validation of proper sealing and shipping, assigning a LAN (Laboratory Accessioning Number), and finalizing any required data entry that an electronic chain of custody system may omit.

During Screening, a preliminary drug abuse scan is performed. This step is an economical way to exclude drug presence in most samples; however, results must be confirmed to be admissible legally. Samples that return a positive indication at Screening require additional confirmation.

Should a positive result arise during Screening, additional hair from the collected sample is prepped for Extraction. This step extracts drugs present in hair at significantly lower concentrations compared to alternative methodologies (e.g., urine or oral fluid), underscoring the complexity of hair drug testing.

GC/MS, GC/MS/MS, or LC/MS/MS are employed for Confirmation of any positive Screening results. Any sample turning up positive undergoes cleaning prior to confirmation if necessary. The complete lab protocol, from Accessioning to Confirmation, is rigorously evaluated under CAP (College of American Pathologists) standards and in accordance with ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Prolonged detection timeframe: Hair drug evaluations can capture drug use for up to three months, unlike urine tests which have limited durations.
• High resistance to falsification: Attempting to circumvent a hair drug test is notably challenging, enhancing precision.
• Tracks usage patterns: Hair tests reveal trends in drug consumption over periods, not merely immediate use.

Limitations:

• Delayed detection: Drugs generally become evident in hair 5-7 days post-use.
• Expense: Hair drug tests typically cost more than other testing options.
• Variability in outcomes: The results can be influenced by factors like hair color or personal hair growth rates affecting drug metabolite levels in hair.

Note: Referred to colloquially as "hair follicle tests," this examination targets hair strands rather than the follicles 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.
