WE CAN KEEP CURB OVER CORONA VIRUS CASES THROUGH COVID-19 TESTING:

KEYWORD: COVID-19 TESTING

Covid -19 testing is the one of the greatest initiative to overcome the rapid situation of novel corona. Covid-19 testing is the method in which patient is deducted that whether he is the patient of corona virus or not.

Through this covid-19 testing we keep curb on the rampant cases of corona virus. 

TYPES OF COVID-19 TSETING:

There are different types of covid-19 testing which are mentioned below:

• Polymerase chain reaction (PCR) tests are sent away to a lab to diagnose disease

• Lateral flow tests (LFTs) can diagnose Covid-19 on the spot, but aren’t as accurate as PCR tests

• Antibody (or serology) tests can’t diagnose active infection, but they can help to tell if a person has immunity to Covid-19

PSR TESING:

PCR tests are used to directly screen for the presence of viral RNA, which will be detectable in the body before antibodies form or symptoms of the disease are present. This means the tests can tell whether or not someone has the virus very early on in their illness. During Covid-19 testing PSR, substances known as reverse transcriptase or DNA polymerase are added to a nasopharyngeal sample in a lab.

ANTI-BODY TESTING:

Antibodies are generated after a week or two, after which time the virus should have been cleared from the system. But it tells you who’s been infected and who should be immune to the virus.”

A study published in the journal Immunity has found that people who recover from even mild cases of Covid-19 produce antibodies for at least five to seven months, and could do so for much longer.

LATERAL FLOW TEST:

LFTs are similar to PCR tests, in that they’re both types of antigen test, designed to pick up active Covid-19 testing infection rather than antibodies to the disease. With a Covid-19 LFT, a nasopharyngeal sample is placed on a small absorbent pad, which is then drawn along the pad via a capillary line to a strip coated in antibodies, which bind to SARS-Cov-2 proteins.
