Hi I Recently Got 2 Bottles One Is For My

Hi i recently got 2 bottles one is for my urine and the other is for stool I believe. One has a green cap and pink fluid and the other has a yellow cap and clear fluid. The green one says fecal and the yellow says stool. So now I'm confused. I was given them to bring to a lab for testing. So which one is for urine and which one is for stool? Thank you
