COVID-19 Testing in North Bergen, NJ : FAQs

What are emergency signs for COVID-19?

After two to fourteen days of exposure to Covid-19, people can experience a various number of symptoms. Some of these are fatigue, muscle or body aches, cough, fever, difficulty in breathing, loss of taste or smell, vomiting, sore throat, diarrhea, and congestion.

Who may be advised to get tested for COVID-19 in North Bergen, NJ?

Those who have been in close contact with a person who tested positive for Covid-19 or those who are experiencing symptoms of the virus are advised to get tested for Covid-19. For documentation or travel purposes, you can also avail of a test for Covid-19.

What is the difference between a diagnostic test and an antibody test?

A serology test, also known as an antibody test, is used to examine your results to show if you were infected with the virus prior. A viral test, or a diagnostic test, is used to search for indications that would tell that you are currently infected.

Do antibodies provide immunity to reinfection?

According to the Center for Disease Control and Prevention (CDC), there is still no answer yet to this question. Research is currently still ongoing on the matter. No answer has come up yet on the level of antibodies required for immunity from reinfection. Studies also have yet to show if those people with antibodies, although themselves immune to the virus, can still have the capacity to spread it to other people.

How does an antibody test for COVID-19 work?

Through the examination of the antibodies specifically targeted to fight SARS-CoV-2, a blood test called an antibody test, can show if you have been infected previously by the virus.

How accurate is the antibody test in Union City, NJ?

Except when there is a delay in viral testing, it is discouraged to use antibody tests to diagnose a current COVID-19 infection. This is because it takes one to three weeks after infection to generate antibodies, so the tendency is that the antibody test may end up not showing if you have an existing COVID-19 infection. The test’s accuracy will be largely dependent on the percentage of the population who have been exposed to the virus.

When is the rapid antigen test for COVID-19 most effective?

When tested during the early stages of viral infection when the viral load is at its peak, rapid antigen tests are at its most effective. These tests may also be helpful in diagnostic tests on a person who has come into contact with a confirmed COVID-19 case.

What influences the likelihood of false-positive or false-negative diagnostic test results?

A number of factors can influence the likelihood of a false-positive or a false-negative diagnostic test result. The specimen collection’s quality and timing, the patient’s biology, as well as a laboratory’s usage of chemicals and instruments in performing a test, are some of these factors. When testing for accuracy, laboratory tests are characterized by their sensitivity, which is the ability to perceive a positive case; and specificity, which on the opposite, determines a negative case. A false-negative result is thus less likely to be provided by a sensitive test. A false-positive test is less likely to be yielded by a specific test.
