COVID-19
MOLECULAR PCR TESTING
Currently, PCR is used in the majority of the Covid-19 tests from which all of the reports are derived. Besides, it aids medical professionals in identifying the RNA that contains the virus’ genetic code. That said, only if the virus is present and someone is infected actively, this kind of phenomena is possible.
Also, instead of detecting the presence of the body’s immune response, or antibodies, PCR tests are used to straightaway detect the antigen presence. Besides, the tests can determine whether or not someone has the virus very early on with the detection viral RNA, which will mark its presence in the body before the formation of antibodies or the presence of any symptoms.
At RR Labs US, We can tell who is infected by using PCR. Moreover, they are able to communicate with those they have been in contact with while being quarantined, just in case. Also, the ability to break the transmission chain and gain a clearer understanding of what’s going on is the real benefit of the current major diagnostic tests.
On the other hand, Public health officials can gain a better understanding of the spread of a disease like Covid-19 within a population by scaling PCR testing to screen sizable portions of nasopharyngeal swab samples from within a population.
Collection Type: Nasopharyngeal
SEROLOGIC ANTIBODY TESTING
We can determine the population’s infection rate through an antibody test. Because the antibodies are produced a week or two after the virus should have been eliminated from the body, it won’t be possible to determine who is infected. But it also lets you know who has been exposed to the virus and who should be immune to it.
Moreover, the length of any immunity period following a Covid-19 infection is not yet known. Besides, historical research has shown that individuals who survived the SARS outbreak in 2003-2003 had antibodies in their blood for years after they had recovered. Although coronaviruses are the cause of both SARS and Covid-19, it is still too early to predict whether Covid-19 will elicit a similar immune response. According to reports, some individuals have contracted the virus twice, meaning that they never developed any immunity at all.
All things considered, the knowledge could assist in removing the social isolation-related restrictions on movement if public health officials can determine what percentage of the population is theoretically immune to the virus.
In contrast to PCR tests, which frequently use swabs to detect Covid-19, antibody tests typically require blood samples. This is due to a significant and detectable antibody presence, despite a very small amount of the coronavirus circulating in the blood compared to the respiratory tract.
Collection Type: Blood
