What did you do regarding the sink drain?

Holly Ryszek (4:38)

For the sink drain, we tested it with a chemical called tetramethylbenzidine. We call it TMB for short, and essentially, it's a presumptive test for blood.

So you have a swab and you'll swab the area that you're interested in. And if either your swab turns a blue-green color, that means that it is possibly suspected blood. If the swab does not change color, that means that it is not suspected blood.
