PCR Test: Difference Between PCR and Antibody Test

An increasing number of people are being diagnosed with COVID. Numerous individuals have lost loved ones, and this trend continues. The Centers for Disease Control and Prevention (CDC) puts the death toll from this virus at over a million. Health officials are making efforts to encourage people to get vaccinated. 

Patients with coronavirus symptoms can have their saliva tested to diagnose active infection with COVID-19, just like a nasal swab. Although nose swabs are more routinely used, saliva tests are just as accurate. 

What is PCR? 

For checking the presence of coronavirus, the PCR method amplifies a predetermined region of the virus's DNA. For a qualitative evaluation of the virus's presence, PCR test Huntsville uses a procedure that involves producing hundreds of copies of this genetic material. While the test can identify a present infection, it cannot predict the course of future disease. 

The precision of PCR Tests 

Know that your PCR can return a false negative result, despite the fact that it may infect you with the active coronavirus strain. It happens if the sample was taken inappropriately or someone performed the test too soon after exposure. Therefore, it is impossible to dismiss the possibility of having COVID-19 even if the results of your swab test are negative. 

Healthcare providers recommend being tested about seven days after exposure, or around 3-4 days after symptom onset, for the most reliable findings. If you want to know how reliable your provider's particular test is, ask them. 

However, I can recommend to you the US Travel and COVID Testing Lab in Huntsville. They offer same-day results with high accuracy and efficiency. 

What is an antibody test?

Those curious about their potential exposure to the COVID-19 virus can take an antibody test to see if they have ever been exposed to the virus before.  

Small proteins called antibodies are an integral element of our immune system. In the case of COVID-19, they are manufactured to protect the body from that particular virus. 

This blood test is designed to detect coronavirus-specific antibodies. A person with COVID-19 often develops antibodies within a week to two of being ill. 

How It Works?

By taking this test, US Travel and COVID Testing Lab can determine if you are immune to COVID-19. Although the test can tell us whether or not you have ever been exposed to the virus, this test is not routinely utilized for rapid diagnosis in the same way as PCR and antigen testing are. Testing for viral antibodies can confirm a patient's prior illness long after they've made a full recovery. 

In Conclusion 

There are benefits and drawbacks to each COVID test option. Armed with this knowledge, you can pick the test that will give you the most accurate results. The PCR test, for instance, may not be your best option if you require timely findings. 

Everybody wants this pandemic to end; therefore, we all must take measures (like getting your COVID status checked often). The fact that COVID is often symptomless emphasizes the significance of testing for it.
