Corona infected but why test report negative? Know what to do in this situation

There are two types of tests to check for corona infection: RT-PCR and antigen test.

But complaints are coming from many places that despite all the symptoms, the results are coming negative in the test.

Now the question arises that what are the reasons behind this?

RT-PCR means real time reverse transcription polymerase chain reaction. In this test, a sample (swab) is taken from the nose or throat.

According to experts, RT-PCR can confirm whether a person is infected with the corona virus.

Once the swab is taken from the patient's nose or throat, it is put into a fluid. The virus on the cotton mixes with that substance and remains active in it.

This sample is then sent to the lab for testing.

What is 'false negative'?
Mumbai-based Namrata Gaur (name changed) had a fever for five days, but test results came back negative.

According to him, "When symptoms started appearing in my body, the doctor suggested me to do the RT-PCR test. The result came negative. But the fever and cough persisted. The doctors started treatment. After a few days another test It turned out that I was corona infected. "

Experts say that the RT PCR test gives reliable results regarding corona-infection. But, sometimes it also gives 'false negatives'.

Dr. Farah Ingale, director of the Department of Internal Medicine at Fortis-Hiranandani Hospital in Vashi, Mumbai, says, "Some patients show all the primary symptoms of Kovid but, the results are negative. In medical parlance, it is called a negative negative."

"It can be dangerous because it allows patients to move freely and spread the infection."

What are the reasons behind the negative report even after having all the symptoms?
According to Dr. Farah Ingley, omissions while taking the swab, wrong way of taking the swab, low amount of fluid required to keep the virus active, improper transportation of swab samples can be the reason for falls negative.

Sometimes the viral load in the patient's body is very low, so a negative report comes despite the symptoms.

A microbiologist in the Navi Mumbai metropolitan municipality, on the condition of anonymity, said, "Corona is a type of ribonucleic acid (RNA) virus. It is a very sensitive virus that can lose vitality at any time. So, The cold-chain needs to be managed properly. If the virus is exposed to normal temperature during transport, it loses its vitality and the report becomes negative. "

Experts say that sometimes people taking swab samples are not properly trained. They do not take swabs properly, which leads to wrong results.

Does drinking or eating water affect test results?
Dr. Ingley says, "If the patient has drank water or eaten something before the Kovid-19 test, it may affect the RT-PCR results.

She says, "Many elements of the body affect the test."
