Hair Follicle Drug Testing - Elkton, MD

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair offers an extensive history of alcohol and other substances by embedding biomarkers within the fibers of the hair as it grows. When extracted near the scalp, hair can reveal up to a roughly 90-day detection period for alcohol and drugs. Hair is straightforward to collect, relatively hard to tamper with, and simple to transport.

A 1.5-inch sample comprising about 200 hair strands (approximately a #2 pencil's diameter) closest to the scalp equates to 100mg of hair, the preferred sample size for screening and verification. For EtG, additional tests, and/or over 10-panel screenings, 150mg of the sample is advised. We suggest weighing the sample with a jeweler’s balance. If scalp hair is absent, an equivalent amount of body hair can be gathered. Referring to head hair indicates only scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

The primary steps in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails initial sample input into a lab’s system. This involves confirming the sample was sealed and transported correctly, assigning a unique LAN (Laboratory Accessioning Number), and finalizing any missing data entry not available through an electronic chain of custody system.

Screening is a preliminary quick assessment for drugs of abuse. Although Screening is an economical method to exclude drug usage in most samples, a positive screen requires confirmation to be legally acceptable. Samples presumptively positive in Screening need further confirmation.

If a sample is presumed positive during Screening, further hair is taken from the initial sample and prepared for Extraction. Here, drugs are extracted from hair at significantly lower concentrations than other techniques (e.g., urine or oral fluid), making hair drug testing more complex.

Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed before confirmation as necessary. The comprehensive lab process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests which have limited detection periods.
• Hard to falsify: Tampering with a hair drug test is challenging, ensuring more reliable results.
• Reveals usage patterns: It provides data on drug use over time, not just recent consumption.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair after roughly 5-7 days.
• Price: Hair drug tests typically cost more than other testing methods.
• Result variability: Elements like hair color and personal variances in hair growth can influence drug metabolite concentration within hair.

Note: While commonly termed "hair follicle tests", the analysis evaluates the hair strand and not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

Hair follicle tests in Elkton, MD offer better detection and reliability over urine tests. They detect drug use for up to 90 days, providing a more comprehensive usage history.

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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing.
