Hair Follicle Drug Testing - Millersville, MD

What it is, How it works

Hair testing is recognized as an effective approach for identifying drug and alcohol consumption. Hair accumulates a long-term history of alcohol and other drugs by embedding biomarkers within the fibers of the hair as it grows. When acquired near the scalp, hair can provide a detection period for alcohol and other substances of up to roughly three months. Hair is straightforward to gather, relatively hard to alter, and simple to transport.

A 1.5-inch portion consisting of around 200 hair strands (approximately equivalent in size to a #2 pencil) nearest to the scalp offers 100mg of hair, the ideal specimen quantity for both screening and validation. For EtG, additional tests, and/or panels exceeding ten, a sample of 150mg is advised. We suggest using a jeweler’s scale to weigh the specimen. Should scalp hair be absent, a similar amount of body hair may be collected. When referring to head hair, we denote this as scalp hair exclusively. Body hair pertains to all other types of hair (facial, axillary, etc.).

Process Overview

The laboratory procedure for drug test results includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning constitutes the initial integration of a sample into a laboratory’s framework. This encompasses confirming that the sample was appropriately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not available through an electronic chain of custody system.

Screening represents an initial rapid inspection for substance abuse. Although Screening is an economical way to exclude drug usage for most samples, a positive screen requires confirmation to be valid in legal proceedings. Any samples with presumptive positives in Screening necessitate a secondary validation.

If a sample is potentially positive during the Screening phase, additional hair is retrieved from the original specimen and prepared for Extraction. At this stage, drugs are extracted from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), which is why hair drug screening is the most challenging technique to execute.

Verification of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed before confirmation as necessary. The entire laboratory workflow from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug assessments can reveal drug usage for up to 90 days, in contrast to urine tests which offer a briefer detection period.
• High resistance to tampering: It is remarkably difficult to manipulate a hair drug test, thus achieving more precise results.
• Offers a chronological profile: It is capable of providing a usage pattern over time, beyond just recent consumption.

Limitations:

• Cannot identify recent consumption: It requires roughly 5-7 days for substances to become detectable in hair.
• Expense: Hair drug tests are typically more costly compared to other testing methods.
• Outcome variability: Elements such as hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Commonly labeled as "hair follicle tests", the assessment actually scrutinizes the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
