DU's economic RT-LAMP kit to detect coronavirus in 40 minutes

Jun 08, 2020

Dhaka (Bangladesh) June 8: Dhaka University (DU) claims to have detected the SARS-Cov-2 coronavirus with Rapid colorimetric detection, also known as the RT-LAMP kit.
A press release signed by DU Public Relations Officer Mahmood Alam said the university's biochemistry and molecular biology department, led by its Chairperson Prof Zeba Islam Seraj, successfully detected Covid-19 using the RT-LAMP kit.
"We used samples which were tested at the DU laboratory earlier and pronounced positive and negative using real-time polymerase chain reaction (RT-PCR) kits," Prof Zeba said.
"The samples that came positive earlier showed yellow colour and earlier negatives are showing pink after running it through the RT-LAMP kit. The new economical system gave accurate results," she added.
Prof Zeba also said: "It is a kit to identify any RNA or DNA. It was first used to identify Covid-19 in Wuhan, China, and later in a laboratory in the USA and in Canada."
She added: "The advantage of this test is that it can be conducted in 40 minutes, and requires a simple incubator, meaning it does not require a complex device like a PCR machine. It will cost Tk600 maximum for a test, while it costs around Tk3,000 to test in a hospital with RT-PCR, which is also more time consuming."
The Biochemistry and Molecular Biology department of the university and Biotech Concern - the sole distributor of the new kit in Bangladesh - have jointly applied for effectiveness testing with Bangabandhu Sheikh Mujib Medical University Hospital (BSMMU) and will send it up to the drug administration board later for permission, the press release said.
USA based molecular biology reagent and kit manufacturer New England Biolabs produces the RT-LAMP kits.
