False test for COVID19

Their are lot of cases of coronavirus , where people come with no symptoms 

So what's false positive COVID 19 or what is reality of no symptoms in covid 19 

First keep in mind .

Yaa , there are two types of coronavirus infectant 

1) patients showing symptoms

2) patients without symptoms 

In this is article we are going deep in false test result covid 19 ( patient shown positive to covid 19 although not positive ) 

Before getting deeply dived into reasone behind false result we should get how the sample is tested for covid 19 virus 

Their is famous technique known as RTPCR 

Well We have discussed it before 

Click here to get known to RTPCR or Reverse transcription polymerase chain reaction

This is sensitive technique to detect presence of virus in sample of patient .

Many times people are reported positive claiming no symptoms , but due to positive shown in test , they are kept in hospital for treatment ( well good , this should be done , we don't want to rescue the life of patient )

While the process of RT PCR is going on for sample , if any single drop of another sample ( positive for covid 19) came in contact with sample on testing then their is high probability of this sample to show positive although sample may not be 

Number of cases are reported positive by this RT PCR although they were not ! 

Hence if having chance then going through the test again will best insure the presence of virus .

Keep in mind this is not only reasone for false result of covid 19 test 

Their are several reasone too ..

That we will discuss later on..
