Hair Follicle Drug Testing - Herricks, NY

What it is, How it works

Hair analysis is now recognized as a highly effective approach for identifying drug and alcohol consumption. Hair can offer an extended record of alcohol and drug use by encapsulating biomarkers within the hair strand as it grows. When sourced near the scalp, hair can provide up to about a three-month detection timeframe for alcohol and other substances. Hair is straightforward to collect, relatively hard to tamper with, and convenient to send.

A 1.5-inch sample consisting of roughly 200 hair strands (similar in size to a #2 pencil) closest to the scalp provides 100mg of hair, the optimal amount for screening and verification. For EtG, additional tests, and/or panels beyond 10, a 150mg specimen is suggested. It is advisable to weigh the sample using a jeweler’s scale. If scalp hair is not available, a comparable quantity of body hair can be gathered. When mentioning head hair, we refer solely to scalp hair, while body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The four essential stages in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the preliminary handling of a sample into a laboratory’s framework. This step entails confirming that the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not included by an electronic chain of custody system.

Screening is a preliminary rapid assessment for substances of abuse. Although Screening is an economical method to exclude drug use in the majority of samples, confirming a positive screen is required for court admissibility. Any samples with presumptive positive results in Screening necessitate a secondary validation.

If a sample presents a presumptive positive in the Screening phase, more hair is extracted from the original specimen and set up for Extraction. During this step, drugs are isolated from hair at a significantly lower concentration than in other techniques (e.g., urine or oral fluid), making hair drug screening the most challenging technique to perform.

Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. From Accessioning to Confirmation, the complete laboratory procedure is assessed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug use spanning up to 90 days, unlike urine tests that provide a shorter detection window.
• Challenging to falsify: Tampering with a hair drug test is very challenging, resulting in more precise outcomes.
• Exhibits historical data: It can demonstrate a drug use pattern over time, beyond just recent activity.

Limitations:

• Inability to detect recent usage: It generally takes around 5-7 days for drugs to become noticeable in hair.
• Expense: Hair drug assessments are generally pricier than alternate drug testing techniques.
• Result variations: Attributes such as hair pigmentation and individual differences in hair growth can influence the concentration of drug metabolites within the hair.

Note: Although frequently termed "hair follicle tests", the analysis itself examines the hair strand and not the follicle beneath 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. 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.
