The forensics team did not test the bloody towels because of microbial contamination, IIRC. The forensics team may have only tested the door handle and not the door to Meredith's room, and we know that Raffaele touched the door. These are merely examples; the principle is that individuals deposit DNA in various ways at various times, but that does not mean that every scrap of DNA is found and tested.
The decomposition only affected one towel. They tested it, but the results were negative.
I don't believe they tested the outside door handle.
Here is a summary of some of the DNA results, including the ones from Meredith's room:
