Okay kiddo, imagine you have a string that you use to measure things like how tall you are or how long your toy car is. The estermann measure is like that string, but instead of measuring things, it measures how well your body is working.
You know how when you go to the doctor, they use a thermometer to check if you have a fever? Well, the estermann measure is another tool that doctors use to check if your body is fighting infections and doing all the things it should be doing to keep you healthy.
The estermann measure looks at things in your blood called cytokines, which are like little messengers that help your body communicate and fight off germs. By measuring the levels of cytokines in your blood, doctors can get an idea of how well your immune system is working.
It's kind of like when you're playing a team sport like soccer or basketball, and your coach wants to see how well the team is working together. They might watch to see how often you're passing the ball to each other or how well you're communicating on the field. The estermann measure works the same way by looking at how well different parts of your body are working together to fight off infections.
So, in summary, the estermann measure is like a special string that doctors use to measure how well your body is fighting off germs and staying healthy, by looking at little messengers in your blood called cytokines.
