No because samples are only collected from places where Keela alerted to. AFAIK. You can test for cadaver odour. In Eddie's case if there isn't a chunk of flesh in sight there is nothing to test for.
Keela had to have her nose very close to the source before she would alert. However, Grime stated that Eddie had alerted to the floor tiles , whereas his nose appears to be directed at the sofa fabric right before the barking.
Was Keela given the opportunity to examine the sofa at close quarters?
Was the cellular material beneath the floor tiles a chance finding rather than what Eddie actually alerted to?
Could realisation of a sofa alert have been useful to the investigation?
There is a method of testing for some elements of cadaver odour contaminant, not dissimilar to the methods used for his scent transfer pads as a training aid. It was used in the Casey Anthony case.

There are still outstanding motions the judge must rule on. They include plant root growth where Caylee’s remains were found, plus chloroform levels and air samples from the trunk of Casey’s car. State witness Dr. Arpad Vass is a research scientist and forensic anthropologist at Oak Ridge (Tenn.) National Laboratory who is well known in the field of decomposition odor analysis. He ran gas chromatograph/mass spectrometer tests on air and carpet samples from Casey’s trunk and found evidence of human decomposition and a high level of chloroform. The defense claims the chloroform was from Caylee’s bathing suit. If Judge Perry allows this evidence at trial, he will be the first judge in the U.S. to do so.
