Hair Follicle Drug Testing - Foster, NE

What it is, How it works

Hair analysis has emerged as a highly effective means for identifying present or past drug and alcohol consumption. Hair strands maintain a prolonged record of substance intake by capturing relevant biomarkers within the strands' fibers. Obtaining hair close to the scalp offers nearly a 3-month retrospective detection period for substances. Hair is straightforward in collection, challenging to alter, and convenient for transportation.

A 1.5-inch segment consisting of approximately 200 strands near the scalp equates to 100mg, forming the optimal amount for testing and results validation. For EtG, additional tests, or those involving over 10 panels, 150mg is advised. Utilizing a jeweler’s scale to measure the hair is suggested. In cases where scalp hair isn’t available, a comparable quantity of body hair can be used. References to head hair imply solely scalp hair, while body hair encompasses all other types, including facial and axillary.

Process Overview

The laboratory processing of drug tests is segmented into four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning constitutes the initial incorporation of a sample into the lab system. This involves confirming proper sealing and shipment, generating a LAN (Laboratory Accessioning Number), and executing any auxiliary data entry beyond what is provided through an electronic custody chain.

Screening provides a preliminary assessment for substance abuse indicators. While cost-efficient and generally effective at excluding positive tests in most samples, any positive screening outcome must gain verification for judicial acceptance. Samples exhibiting potential positivity during Screening undergo secondary confirmation.

Presumptive positives from Screening see additional hair allocated from the original sample for Extraction. Here, substances are isolated from hair at reduced concentrations versus other methodologies (e.g., urine, saliva), thus rendering hair drug tests as one of the most intricate methodologies for execution.

GC/MS, GC/MS/MS, or LC/MS/MS methods validate any Screening positives. Presumptive positive samples receive washing prior to confirmation as required. All processes from Accessioning through Confirmation undergo audit compliance under CAP (College of American Pathologists) and adhere to ISO / IEC 17025 standard accreditation.

Advantages of hair drug testing:

• Extended detection span: Capable of identifying substance use up to 90 days, as opposed to urine analyses with reduced detection durations.
• Immunity to tampering: Hair drug analyses are notably tamper-resistant, enhancing accuracy.
• Longitudinal data: It offers a consumption pattern over time, unlike isolated recent usage detections.

Limitations:

• Inability to detect immediate usage: Drugs require approximately 5-7 days to become identifiable in hair.
• Higher cost: Hair testing usually incurs greater expenses than alternative methods.
• Result disparities: Variables such as hair color and personal hair growth differences may alter metabolite concentrations.

Note: Though frequently termed "hair follicle tests", the actual analysis is performed on the hair shaft rather than 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented.
