A rapid diagnostic test is like a special test that doctors use to quickly find out if someone is sick. It is kind of like a magic puzzle that can tell us if there are dangerous germs in your body, like when you have a cough, fever, or other signs of being sick.
The test works by taking a little bit of a person's blood, urine, saliva or other body fluids (like from the nose or throat) and putting it on a special strip of paper or a small device. This paper or device has special chemicals on it that can stick to the germs in your body and show us if you are sick or not.
Some rapid diagnostic tests can give results in just a few minutes, while others may take a little longer. Once we have the results, we can use them to figure out what kind of medicine you might need to help you feel better.
Overall, rapid diagnostic tests are super helpful tools that doctors use to figure out what's wrong with their patients so they can get better quickly!
