Medical options include the use of a PCR Travel test and antibody checks. This article compares the two. Doctors and care professionals are in a struggle to track and recognize the pandemic. However, the accelerated spread of Covid-19 has prompted a series of experimental testing. This involves screening for an extremely infectious virus. But for most of March and April, Illinois — like most states — lagged in research. On the same note, more development has been ramping up throughout the state.

What are the available solutions?

PCR and antibodies. Here’s a breakdown of both — and some of the obstacles.

A PCR test relates to hospitals. Doctors use these kits to check whether an active infection is present in a patient. At present, the most reliable way to do that is through this method. This screening detects the virus’s trace elements in samples from the nose, throat, or saliva.


Although scientists and medical experts agree these methods are vital to discovering who has the infection, none of these is foolproof strategies. For example, if the saliva or nasal / throat sample doesn’t contain enough of the virus, it can be a false negative. The CDC also warns that having a negative result doesn’t mean the person will not get sick. The nation has been dealing with a shortage of equipment, swabs, chemical reagents, and other materials. We need them to conduct and process these for weeks. Some of these samples need to be done by laboratories.

Furthermore, others have documented a lack of laboratory workers. This results in a backlog of screening and lengthy waits for results.

The other solution

The other solution is an antibody test, sometimes called serology testing. This examination looks for blood proteins. At the same time, the body fights an infection, instead of detecting the actual pathogen. Researchers say large-scale experiments can provide critical information about the virus. For example, how prevalent the disease is, how many people contract it without symptoms, and whether survivors are immune.


Some doctors express concerns about the accuracy of certain types of this method. Top physicians in the country are working to confirm the serology process. It may take days to two weeks after the Covid-19 infection for a patient to develop antibodies. Thus, according to the CDC, this may not antibodies even in an infected patient. An antibody screening does not represent a complete method to treat those with the infection as being ill.

Which is better?

Both the PCR Travel test and serological kits are ideal. Still, they are better than not checking for Covid-19 at all. So, they provide useful knowledge to medical practitioners on diseases. The public health authorities and researchers may also use these kits.
Even with the current uncertainties, our primary challenge is not the accuracy of these. Rather, it involves the fact that there are not enough people having access to them.
