IQLS will be participating at the International Symposium of the World Association of Veterinary Laboratories Diagnosticians (ISWAVLD) taking place in Lyon, France, from June 29 to July 1. ISWAVLD is a renowned meeting place for all veterinary diagnostic laboratories, biologists, veterinarians and other scientists involved in laboratory diagnostics, bringing together more than 500 participants biannually. In addition to presenting the latest innovations around diagnostics in all areas of animal and environmental health, ISWAVLD 2023 will also focus on the One Health concept in the 2023 edition, and showcase the best work of the veterinary laboratory sector.
As a One Health actor aiming at strengthening public health laboratories, IQLS international One Health laboratory expert, Dr. Arsen Zakaryan will be presenting the important results of a study on “Dried tube specimen (DTS) preparation and stability validation for brucellosis serological external quality assessment and quality control materials in resource-limited settings”
Brucellosis remains one of the major zoonotic diseases worldwide and requires a One Health approach for early detection and control. One of the crucial components for brucellosis control and spread is timely and reliable laboratory diagnosis. External quality assessment is a key component of laboratory quality assurance to evaluate performance and identify possible insufficiencies in laboratory practices. Implementation of brucellosis external quality assessment in resource-limited countries is rare and challenging due to logistical and financial constraints.
The aim of this study, conducted with the Armenian Veterinary Reference Laboratory for Especially Dangerous Pathogens, was to evaluate the preparation and stability of dried tube specimens for external quality assessment of brucellosis serological testing that could be used in resource-limited countries to avoid logistical and financial limitations associated with use of sera.
In conclusion, DTS maintains integrity of serum samples for serological testing of brucella infection and can be a powerful tool for external quality assessment providers, as it decreases shipping costs and avoids challenges in maintaining cold chain shipments between the provider and the recipient laboratories. Moreover, it has great prospects for enabling expansion of external quality assessment programs within One Health to involve human health laboratories, as well as to include lower tier labs in resource-limited countries to monitor and improve the quality and accuracy of brucellosis testing. The DTS method could be used for preparation and transportation of clinical samples from remote areas without cold chain logistics.
