Hair Follicle Drug Testing - Captains Cove, VA

What it is, How it works

Hair testing is perceived as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and drug use by incorporating biomarkers into the fibers of the growing hair strand. When gathered near the scalp, hair can offer approximately a 3-month detection period for alcohol and other drugs. It is simple to collect, somewhat challenging to tamper with, and easy to ship.

A 1.5-inch section of about 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal amount for both screening and confirmation. For EtG, additional tests, and/or more than 10-panel tests, 150mg of the sample is advised. Utilizing a jeweler's scale to weigh the sample is recommended. If scalp hair is unavailable, a comparable amount of body hair can be collected. Reference to head hair implies scalp hair specifically, whereas body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory procedures for processing a drug test result include four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial integration of a sample into the laboratory's system. This process includes ensuring the sample is properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry absent in an electronic chain of custody system.

Screening consists of a preliminary rapid analysis for drugs of abuse. Although Screening is an economical method to exclude drug consumption in the majority of samples, a positive outcome requires confirmation to be deemed valid in legal scenarios. Any samples with a presumptively positive result from Screening necessitate a secondary confirmation.

If a sample exhibits a presumptive positive outcome during Screening, additional hair is extracted from the initial sample and prepared for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations than other methods (ex. urine or oral fluid), making hair drug screening the most challenging method to execute.

Confirmation of any positive Screening results is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation if necessary. The whole laboratory procedure from Accessioning to Confirmation undergoes review under the CAP (College of American Pathologists) Hair designation as well as accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests which have a shorter detection period.
• Hard to falsify: It is exceedingly difficult to cheat a hair drug test, thus enhancing result accuracy.
• Provides historical insight: It reveals a pattern of drug use over time, not merely recent consumption.

Limitations:

• Unable to detect recent usage: Drugs become detectable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug tests are typically pricier than other testing methods.
• Result variations: Elements like hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: Although often termed as "hair follicle tests", the analysis is conducted on the hair strand, not the hair 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.
