Hair Follicle Drug Testing - East Johnston, OK

What it is, How it works

With time, hair testing has emerged as a significant method for identifying drug and alcohol use. By capturing biomarkers in the strands of growing hair, it provides a prolonged record of substance usage. Hair collected close to the scalp offers nearly a 3-month detection period for various substances. It's straightforward to gather, quite resistant to tampering, and convenient to transport.

A 1.5-inch hair sample containing about 200 strands (comparable to a #2 pencil thickness) near the scalp yields 100mg, which is the optimal amount for analysis. For EtG, additional tests, and screenings beyond 10 panels, 150mg of hair is preferred. Utilization of a jeweler’s scale is advised for measuring the specimen. If scalp hair cannot be obtained, a similar amount of body hair is acceptable. 'Head hair' refers exclusively to scalp hair while 'body hair' encompasses all other types (facial, axillary, etc.).

Process Overview

The lab processing of a drug test follows four main steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial integration of a sample into a lab’s system, ensuring proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any missing data entry not covered by an electronic chain of custody system.

Screening acts as an initial assessment for substance presence. Though cost-effective, a positive screen requires confirmation for court admissibility. All samples that show presumptive positivity need secondary verification.

If Screening indicates positivity, additional hair from the original sample is utilized for Extraction. During this phase, drugs are isolated from hair at lower concentrations compared to other methods (e.g., urine or oral fluid), contributing to the complexity of hair drug testing.

Confirmation of a positive screen result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptively positive undergo washing before confirmation as required. The full laboratory workflow, from Accessioning to Confirmation, is overseen under both the CAP (College of American Pathologists) Hair guidelines and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use over 90 days, unlike urine tests which have a more limited detection window.
• High resistance to tampering: Cheating a hair drug test is notably challenging, leading to more reliable outcomes.
• Yields longitudinal data: It illustrates usage patterns, offering insight into long-term substance intake.

Limitations:

• Inability to detect recent intake: It requires around 5-7 days for drugs to be traceable in hair.
• Higher expenses: Hair drug tests typically cost more than other testing alternatives.
• Inconsistent results: Variables like hair color and individual hair growth differences can influence drug metabolite concentrations within hair.

Note: Although commonly termed as "hair follicle tests", the test examines the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in East Johnston, OK Hair drug tests offer a reliable and thorough advantage over 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. 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.
