Hair Follicle Drug Testing - Ferndale, WA

What it is, How it works

Hair analysis presents itself as an effective method for identifying the consumption of drugs and alcohol. The composition of hair archives a timeline of alcohol and substance intake by embedding biomarkers within the strands as they grow. A sample taken near the scalp can reveal alcohol and drug usage over an estimate of 90 days. The collection process is straightforward, challenging to tamper with, and facilitates effortless transportation.

A preferred sample consists of a 1.5-inch section containing roughly 200 strands positioned close to the scalp, yielding 100mg of hair suitable for both preliminary and definitive testing. For EtG, supplementary analyses, and/or tests exceeding 10 panels, 150mg of the sample is advised. It is optimal to measure the sample's weight using a jeweler’s scale. In the absence of scalp hair, a comparable quantity of body hair may be used. When mentioning head hair, we specifically mean scalp hair exclusively. Body hair encompasses all other types of hair (e.g., facial, axillary).

Process Overview

The key procedures in the laboratory management of drug testing results are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a specimen into the laboratory’s system. This step involves ensuring the sample is correctly sealed and transported, assigning it a random LAN (Laboratory Accessioning Number), and completing any absent details not covered by an electronic chain of custody system.

Screening conducts a preliminary assessment for drug misuse. While Screening offers a cost-efficient method to exclude drug use in most samples, positive findings require confirmation to be legally accepted. All samples with a preliminary positive in Screening necessitate additional validation.

If a sample indicates a presumptive positive during Screening, extra hair is extracted from the original sample for the Extraction process. At this juncture, drugs are isolated from the hair at a notably reduced concentration compared to other techniques (e.g., urine or oral fluid), contributing to the complexity of hair drug screening.

The Confirmation of any positive Screening outcome utilizes GC/MS, GC/MS/MS or LC/MS/MS technologies. All samples with preliminary positive results undergo cleansing prior to confirmation if needed. The full laboratory sequence from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and is authorized by the ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair analysis can identify drug consumption for up to 90 days, unlike urine tests which offer a shorter detection span.
• Resistant to manipulation: Cheating a hair drug analysis is extremely challenging, enhancing the accuracy of results.
• Offers historical insight: It can present a timeline of substance use over an extended period, not limited to recent intake.

Limitations:

• Inability to identify recent consumption: Drugs generally become detectable in hair approximately 5-7 days post-use.
• Expense: Hair drug testing tends to be more costly compared to alternative drug testing methods.
• Result variability: Elements like hair color and individual hair growth rates can influence the level of drug metabolites present in the hair.

Note: Although commonly termed "hair follicle tests", this analysis examines the strands of hair rather than the follicles beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Ferndale, WA, hair follicle testing offers clear advantages over urine tests. Hair tests provide more accurate and reliable detection, largely due to their longer detection windows.

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.
