Health experts say a negative coronavirus test result does not mean you are in the clear especially if you have symptoms associated with the disease.
There are many cases where South Africans had to take two tests to confirm that they are Covid-positive.
That is because the first test returned a negative
result despite the patients experiencing severe symptoms related to the Coronavirus.
Acting Executive Director at the Institute for Communicable Diseases Professor Adrian Pur en says one of the reasons for false negative results is the inferior quality of the specimen that's submitted.
He says, "When we use PCR, we all say it's the gold standard or the reference standard.
However, when you taking a specimen, that needs to be done properly.
If you not taking a proper specimen, if it's stored incorrectly, delays in testing, that could lead to a false negative.
There is the antigen test, it will perform fairly well even though they are less sensitive than PCR.
There may be certain conditions where it may well be missed." "https://scontent-jnb1-1.xx.fbcdn.net/v/t1.0-9/138846683_3884011218317900_8847758360235513746_n.jpg?_nc_cat=105&ccb=2&_nc_sid=8024bb&_nc_ohc=54hXh7IryG4AX9n7xYk&_nc_ht=scontent-jnb1-1.xx&oh=32b78feaa6b8b140f20e57549c038031&oe=60283554"
