Hair Follicle Drug Testing - Melrose, MA

What it is, How it works

Hair testing is recognized as a robust method for identifying the use of drugs and alcohol. Hair captures a long-term record of alcohol and drug consumption by embedding biomarkers within the fibers of the growing hair. By collecting hair near the scalp, it offers about a 3-month detection period for alcohol and drugs. Hair is easy to collect, challenging to tamper with, and simple to transport.

A 1.5-inch section of roughly 200 hair strands (comparable to the width of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal quantity for both screening and confirmation. For tests like EtG additions and panels exceeding 10, a specimen of 150mg is preferred. It is advised to measure the sample on a jeweler’s scale. If scalp hair is absent, a corresponding measure of body hair may be used. When discussing head hair, it pertains exclusively to scalp hair. Body hair refers to all other forms, including facial and axillary hair.

Process Overview

There are four essential steps in processing a drug test in the lab: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the first processing phase where a sample enters the laboratory system. This step ensures the sample was appropriately sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data entry absent from an electronic chain of custody system.

Screening provides a preliminary assessment for the presence of drugs. While a cost-efficient method to eliminate drug use in most specimens, a positive result must be verified to be legally acceptable. All samples with an initial positive screen require further confirmation.

Should a sample test positive in the Screening phase, additional hair is taken from the original sample to prepare for Extraction. Here, drugs are drawn from hair at a significantly lower concentration compared to other methods (such as urine or oral fluids), which accounts for the complexity of hair drug screening.

Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumed positive samples undergo washing before confirmation if necessary. The full laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can reveal drug consumption up to 90 days, whereas urine tests have a shorter detection span.
• Hard to manipulate: Cheating a hair drug test is quite difficult, enhancing result accuracy.
• Historical usage data: It offers an accumulated pattern of drug usage over time, beyond just recent consumption.

Limitations:

• Not indicative of recent use: Drugs require roughly 5-7 days to be detectable in hair.
• Expense: Generally, hair drug tests incur higher costs than other drug testing alternatives.
• Result variability: Elements like hair color and personal hair growth differences can influence drug metabolite levels in the hair.

Note: Frequently called "hair follicle tests", this testing method analyzes the hair strand itself, and not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Melrose, MA, provides numerous benefits over traditional urine tests. One notable advantage is the superior detection period, allowing for the identification of drug use over an extended timeframe.

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.
