If speed, low cost and constraints of molecular testing capacity are the reasons why many States have embraced rapid antigen testing, the test has low sensitivity. Yale University’s saliva test,…
A rapid, inexpensive saliva test developed by Yale School of Public Health in partnership with NBA has high sensitivity. The testing protocol has been made available through “open source”. The…
With over 60,000 daily fresh cases, India has been reporting the highest numbers in the world for the last few days. Yet, the high test positivity rate strongly suggests that…
A low-cost, probe-free RT-PCR COVID-19 detection assay developed by IIT Delhi will be launched tomorrow (July 15). The assay does not require a probe as it uses a fluorescent dye.…
A systematic review and meta-analysis of 40 studies of antibody testing for novel coronavirus (SARS-CoV-2) has found “major weaknesses” in the evidence base for serological tests. The evidence does not…
Researchers at the Mumbai-based Tata Memorial Centre have used Raman Spectroscopy to detect RNA viruses present in saliva samples. It is a proof-of-concept study to analyse non-infectious RNA viruses using…
After displaying extreme reluctance to admit community transmission despite having over 67,000 cases and the nature of the virus spread, India has finally decided to confirm community spread by testing 30,000…
In a first, NIV Pune has developed an ELISA test to detect IgG antibodies that are developed in response to infection by novel coronavirus. The ELISA test, to be manufactured…
