Have you ever heard of the word "poop"? Yes? Well, when we do a "fecal pH test," we test our poop to see if it is too acidic or too basic.
When we eat food, it goes through our stomach and comes out as poop. Our poop has different chemicals in it that make it either more acid or more basic. We test our poop to see if it has too much acid or too much base.
Why is this important? Because sometimes if our poop is too acidic or too basic, it can mean that we have something wrong with our body. Doctors can use the results of the test to figure out what's wrong, and then they can help us get better!
So, in short, a fecal pH test is a test that helps doctors see if there's something wrong with our poop and our body. It's like checking to make sure everything in our body is working properly.
