PATNA: As the number of Covid cases is inching towards 20,000-mark in Patna, the state health department is likely to conduct serological survey to ascertain the extent of virus spread in both rural and urban areas of the district.
A sero survey helps assess the population exposed to SARS-CoV-2 infection using IgG Elisa Test (antibody test). It detects the presence of specific antibodies against the virus.
Rajendra Memorial Research Institute of Medical Sciences (RMRI) at Patna will volunteer the exercise, from collecting blood samples from people to IgG Enzyme-Linked Immunosorbent Assay (ELISA) test to estimate the proportion of population exposed to the virus. The institute has recently installed the CLEA machine for the analysis of IgG antibody in blood samples.
RMRI director Dr Pradeep Das told this newspaper on Monday that the machine was installed on Saturday and the trial run was conducted on 30 blood samples collected. “The IgG antibody were found raised in nine samples while there was no change in the IgG level in the other 21 samples,” he said.
“With the help of this machine, the team will be able to conduct testing of 100 blood samples at a time. It takes only one hour to test 100 samples,” he said.
Dr Das said the state government was planning to conduct the sero survey in Patna, but it had yet to decide how many people would be covered in the survey.
In addition, the blood samples of 6,000 health workers would also be collected for the sero survey in Patna. For the exercise, the RMRI-Patna and the IGIMS will volunteer.
According to sources, the IGIMS team will test around 1,600 samples while 4,400 samples will be tested by the RMRI. The IGIMS has also recently installed the machine to check the IgG antibody in blood samples.
