Laboratory optimization of the production of guanidium-based inactivated transport media to support SARS-CoV-2 PCR testing in Indonesia
Published:  Jun 12, 2022
The availability of a viral transport medium (VTM) is often an obstacle to COVID-19 testing, especially for countries that are not VTM producers, including Indonesia. Therefore, the Parasitology Laboratory of Medicinal Faculty, Universitas Padjadjaran, Indonesia, developed an inactivation transport medium called “VITPAD®” that uses a guanidium-based buffer solution. This study evaluated VITPAD® as a transport medium for swab samples and scaled-up production from 2,000 tubes per month to 60,000 per month to support COVID-19 testing in Indonesia. VITPAD® has good stability and sterility, with a lifespan of over 2 years, and it performs well as a transport medium for COVID-19 samples. The production capacity was successfully scaled-up by implementing scheduling and capacity management, with the first large-scale production of VITPAD® distributed to 26 teaching hospitals in Indonesia.
