With economic activities resuming gradually, corporate houses are increasingly opting for rapid antigen and antibody tests to screen and protect their employees from coronavirus, several diagnostics labs and hospitals in the NCR have said. The Rapid Antigen Test was introduced in the national capital last month and is a quicker and cheaper alternative to the "gold standard" RT-PCR test, which is considered more reliable.
"We are getting antigen test queries mostly through the government. We are also getting queries from corporates that have large employee population who want to get it done for their employees since one or two of their employees have tested positive," said Chetan Kohli, COO of the Seeds of Innocence and Genestrings Lab.

Standard Q COVID-19 Ag detection kit (rapid antigen test kits) is a quick chromatographic immunoassay for qualitative detection of specific antigens to SARS-CoV-2 or the novel coronavirus. The Standard Q COVID-19 Ag detection can be interpreted as positive or negative within 15 minutes of putting the sample into the well by the appearance of test and control lines, which can be read with a naked eye, requiring no specialised equipment.
