According to the university, the test kit is one of the very first in the world that uses RT-LAMP to detect SARS-CoV-2 that causes Covid-19.
Led by Dr Le Quang Hoa, a lecturer of the university’s School of Biotechnology and Food Technology, and Dr Nguyen Le Thu Ha from Innogenex International Science and Technology Ltd Company, the research team found the reverse transcription loop-mediated isothermal amplification (RT-LAMP) technique could be used to detect the novel coronavirus.
Testing results could be seen with the naked eye thanks to the changes in colour of the indicator chemicals.
The RT-LAMP technique can produce results within 30 minutes while the RT-PCR test kits which are also developed by Vietnamese researchers require about 120 minutes.Moreover, the kit does not give out false positives for other types of coronavirus such as SARS-CoV, MERS-CoV, HKU4, HKU1, OC43 or 229E which cause other diseases.
Dr Hoa said that under the framework of a study by Vietnam’s Health Ministry, his team and Sao Thai Duong Joint-stock Company produced two versions of the biological products RT-LAMP COVID-19.
The first version of the test kit was licensed by the Health Minister for temporary circulation so that it could be used for testing at the Institute of Hygiene and Epidemiology. The test kits work in all cases and produce exact results.
Dr Hoa said that the second version was developed with reduced imported materials and used domestic equivalents.
He added that the second version had received CE-IVD certification (European CE Marking for In Vitro Diagnostic devices), which allows distribution across Europe, on May 25. — Vietnam News/ANN
