Radioimmunoassay
Radioimmunoassay is a very fancy way of checking if certain tiny things are inside your body, but they are too small to see with your eyes. Scientists use a special kind of machine to help them find these tiny things.
First, they take a little bit of your blood and mix it with something special called an antibody. This is like a special magnet that only sticks to the tiny things they want to find. The antibody is like a special key that can recognize the tiny things and stick to them.
Next, they add a tiny bit of a radioactive substance to the mixture. This is like adding little stickers that can light up when someone shines a special light on them. The radioactive substance sticks to the antibody, which is already holding onto the tiny things they want to find.
Then they put the blood mixture into the machine and shine a special light on it. The radioactive stickers light up and the machine can find where all the sticker magnets are. This helps scientists find the tiny things they are looking for, even though they are too small to see with their eyes.
This process can help doctors find out if you have certain diseases or conditions that are caused by the tiny things they are looking for. They might also use it to check if you are taking the right amount of medicine to treat your condition. It helps them make sure you are healthy and that your medicine is working the way it should.
