Hair Follicle Drug Testing - Landover, MD

What it is, How it works

Hair testing has emerged as a significant method for identifying drug and alcohol consumption. Hair captures a historical profile of alcohol and drug use by encasing biomarkers within the strands of developing hair. If collected near the scalp, it can yield a detection period of up to roughly 3 months for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and convenient to transport.

A sample measuring 1.5 inches of around 200 hair strands (approximately the width of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the preferred sample size for screening and confirmation. For EtG, additional analysis, and/or panels exceeding 10, 150mg of hair is advisable. We suggest utilizing a jeweler’s scale to weigh the specimen. Should scalp hair be inaccessible, a comparable quantity of body hair is acceptable. When citing head hair, we specifically mean scalp hair. Body hair includes all other hair types (facial, axillary, etc.).

Process Overview

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

Accessioning covers the initial step of integrating a sample into a laboratory’s framework. This ensures the sample was appropriately sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and completes data entry absent from an electronic chain of custody system.

Screening is a preliminary rapid assessment for drug use. Though a cost-effective method to dismiss drug use in most samples, a positive screen requires confirmation to be valid in a legal context. Samples appearing positive in Screening must undergo a subsequent validation.

When a sample yields a presumptive positive result during Screening, additional hair from the original sample is prepared for Extraction. Drugs are extracted from hair at lower concentrations compared to other methods like urine or oral fluids, which makes hair drug screening uniquely challenging.

Any positive screening results must be confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed prior to confirmation as needed. The complete lab process — from Accessioning to Confirmation — is assessed under CAP (College of American Pathologists) Hair designation and meets the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection window: Hair drug tests identify drug usage for up to 90 days, whereas urine tests have a briefer window.
• High resistance to tampering: Manipulating a hair drug test is notably hard, enhancing result reliability.
• Historical use data: It reveals a pattern of usage over time, rather than only recent activity.

Limitations:

• Limited recent use detection: Drugs take approximately 5-7 days to appear in hair.
• Expense: Hair drug tests are typically pricier compared to alternative testing methods.
• Result variability: Differences in factors like hair color and individual growth rates influence drug metabolite concentrations in hair.

Note: Although commonly termed "hair follicle tests," this examination assesses the hair strand, not the follicle below 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.
