COVID Antibody: Zydus Cadila gets nod for ICMR-NIV developed ELISA kit
New Delhi: In a major breakthrough, drugmaker Zydus Cadila has received validation from the National Institute of Virology (NIV), Pune for the first batch of indigenous anti-SARS-CoV-2A (Covid-19) human IgG ELISA test kit for antibody detection of the lethal virus.
As per the Indian Council of Medical Research (ICMR), ELISA Kit has a similar sensitivity of 98.7 percent and specificity of 100 percent. The kit is cost-effective, sensitive, rapid and a large number of samples can be tested at any level of a clinical setting, including public health centers and hospitals.
This comes days after the development of the technology at ICMR-NIV. The technology has been transferred to Zydus Cadila for mass production. Union Health Minister, Dr Harsh Vardhan confirmed the same through his social handle as;
#ELISA based testing is easily possible even at district level. The @icmr_niv technology has been transferred to #Zydus #Cadila for mass-scale production.

Rapid antibody tests are not recommended for diagnosis of COVID-19 infection
-
ï‚· Can be done on blood/serum/plasma samples
-
ï‚· The test result is available within 30 minutes
-
ï‚· The test may come positive after 7-10 days of infection
-
ï‚· The test may remain positive for several weeks after infection
-
ï‚· A positive test indicates exposure to SARS-CoV-2
-
ï‚· A negative test does not rule out COVID-19 infection
These rapid antibody test kits have been validated in the laboratory. However, the performance of the kits may be subject to variation under field conditions.
