18. The method of claim 17 , wherein the pathogen RNA is from bacteria, virus, or parasite.
19. The method of claim 1 , wherein the at least one characteristic is a level of the at least one tissue RNA in the collected sample.
20. The method of claim 19 , further comprising comparing the level of the at least one tissue RNA in the collected sample from the animal to a level of the at least one tissue RNA in a collected sample of an animal in a reference state.
21. The method of claim 19 , further comprising determining the presence of a disease in the animal by comparing the level of the at least one tissue RNA in the collected sample from the animal to a level of the at least one tissue RNA in a collected sample of an animal in a non-diseased state.
22. The method of claim 21 , wherein the disease is cancer or infectious disease.
23. The method of claim 21 , wherein the disease is atherosclerotic disease.
24. The method of claim 1 , wherein the at least one characteristic is an identity of the at least one tissue RNA.
25. The method of claim 1 , wherein the at least one characteristic is an identity of the at least one tissue RNA associated with a disease state.
26. The method of claim 25 , wherein the disease state is infectious disease, cancer, or atherosclerosis.
27. The method of claim 1 , wherein the at least one characteristic is a relative level of at least two different RNAs.
