Hair Follicle Drug Testing - Hyde Park, NY

What it is, How it works

Hair analysis is recognized as a valuable method for detecting drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug use by embedding biomarkers within its growing fibers. When collected near the scalp, hair can offer a detection period of up to about three months for alcohol and drugs. It is easy to gather, relatively hard to tamper with, and convenient to transport.

A 1.5-inch sample consisting of approximately 200 hair strands (equivalent to a #2 pencil's size) closest to the scalp will yield 100mg of hair, ideal for both screening and confirmation. For EtG, additional tests, or analyses exceeding 10 panels, 150mg of the specimen is advisable. We suggest weighing the sample on a jeweler’s scale. In cases where scalp hair isn't available, an equivalent amount of body hair can be collected. By head hair, we mean exclusively scalp hair. Body hair pertains to all other hair varieties (facial, axillary, etc.).

Process Overview

The key steps in laboratory processing of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial processing of a sample into a laboratory’s system. This includes verifying the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not included in an electronic chain of custody system.

Screening performs a preliminary quick scan for drugs of abuse. While Screening is an economical method to rule out drug use in most samples, a positive outcome must be confirmed for court admissibility. Any samples that test presumptively positive in Screening necessitate secondary confirmation.

If a sample tests presumptively positive during the Screening phase, additional hair is extracted from the initial 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 accounts for why hair drug screening is the most challenging methodology to perform.

Confirmation of any positive screening result is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. Every step from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use over a period of up to 90 days, whereas urine tests have a shorter detection timeframe.
• Resistance to tampering: It is highly challenging to manipulate a hair drug test, thus enhancing result accuracy.
• Historical usage insight: It can reveal a history of drug use across a duration, not just recent consumption.

Limitations:

• Inability to detect recent use: It requires about 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests are typically more costly than other drug testing approaches.
• Result variability: Factors such as hair pigmentation and individual hair growth differences can impact the concentration of drug metabolites in the hair.

Note: Despite the term "hair follicle tests" being used, the analysis focuses on the hair strand rather than the hair follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Traditional urine tests fall short compared to hair follicle testing, especially in Hyde Park, NY. Hair drug tests deliver superior detection accuracy and reliability.

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.
