The Antibody test is all the rage right now across the globe. Many countries are now starting to imply mass implementation with the use of Covid-19 kits. So, they can safely isolate those infected and decrease the further risk of spread to healthy individuals. For example, in South Korea, a mass examination was held to tackle this problem early on. Therefore, it resulted in a very vast and countrywide success when battling the disease.

Types and their Mechanisms

There are generally two main types of Covid-19 tests available. Each is having its pros and cons.

Laboratory Services

This is highly sensitive and uses a technique called PCR test in which it locates the RNA of the virus. It has the capability of detecting even one viral particle in a sample. The sensitivity of this is unmatched when compared with other methods. It sure comes at a price, though.

Serum Antibody 

The second one relies on measuring serum in one’s blood. Our body creates many different pathogens in response to the viral particles. Some of these are very useful in our defense. While others being less useful. In this, the scientist coat the tube with purified components of the Covid-19. Then the scientist mixed a blood sample from the patient. After the development, if antibodies are present in the blood, they will bind to the viral particles.

Pros and Cons

It is fast, and many countries are using it as a primary means of testing. But, the analysis only shows positive as long as the virus is in the bloodstream. Not to mention a laboratory and qualified staff required to handle. However, there are portable machines, but these are just recently becoming available for them. And even the fastest ones take around 2 hours. So we still have to wait for them.

Other Method

An antibody test, on the other hand, require weeks to develop. And it also doesn’t detect the virus itself. But, since the pathogen tends to last much longer in blood. It becomes useful to examine if a vaccine works or if a person had any previous contact with the virus. There is a quicker, much cheaper method that works similarly to pregnancy checks. But of course, they are less accurate than the labs. They work by detecting pathogens in your bloodstream.

A modified paper is used instead of a tube. The blood from a patient is taken and poured on the paper. Which then provides a positive or negative sign for the presence of the disease.  Methods like these are still a topic of debate and, therefore, not officially available right now. You may come out positive even if you don’t have a disease. You may have pathogens against something resembling the virus. Or you can come out as negative and carry the Covid-19 virus around and infect other people. Some of these have an accuracy of 80%. So it is a 1/5 chance of the results being inaccurate.

Things to look forward to in the future

Whether you prefer the Antibody test or the other method, there are still many factors to consider. Many different laboratories and teams across the world are looking to develop small, portable devices that are fast, simple, and affordable for everyone to use. By this, there will be an ease in mass implementation of this disease. Medicines Online has a service available for you, where you can book an appointment.
