Yes, a blood test can tell if you are at the risk of
coronavirus disease or not. Scientists say that a simple blood test can reveal which people are at greater risk of coronavirus infection. Researchers have identified a specific molecule indicator in the blood that increases the risk of hospitalization by five to 10 times in those infected with the coronavirus.
According to scientists at Helsinki-based biotechnology company Nightingale Health, Finland, this test can be used to find out which people need to take special precautions to avoid infection and who should be given the Covid-19 vaccine first would be required.
Researchers have explored whether blood indicators can predict which people are at greater risk of hospitalization due to diseases such as pneumonia and COVID-19. They analyzed more than one million blood samples from the UK biobank and identified a particular molecule indicator in the blood that could indicate which people are at greater risk of getting infected with the coronavirus. Scientists said that the risk of hospitalization increases by five to ten times for those whose blood contains this molecule indicator.
