Covid-19, a private lab's chief has urged people to undergo an RT-PCR if they are symptomatic. “We should keep in mind the timing of the RT-PCR test and the type of the test.
The sensitivity of the Rapid Antigen test is far lower than the traditional RT-PCR. So, if there are symptoms, a negative Rapid Antigen test should be followed with an RT-PCR," said Dr Arjun Dang, the CEO of Dr Dangs Lab.
This comes in the backdrop of doctors warning that there are chances of false-negative reports in Rapid Antigen home testing kits even after having Covid symptoms and people should self-isolate themselves as a precaution. “There are two kinds of tests that are being done.
One is the home tests, which are the rapid antigen tests and these have quite a limited sensitivity. These are about 505 as sensitive as the gold standard RT-PCR test, so you may get a false negative test on these testing kits," Dr Harsh Mahajan, the founder and chief radiologist of Mahajan Imaging, was quoted as saying by news agency ANI.
