Virus Identification 9 Cytopathic effects: Detectable changes in the host cell due to viral infection (p. 441) Blood serum (serology) tests Detect antibodies against viruses in a patient Use antibodies to identify viruses in neutralization tests, viral hemagglutination, and Western blot Nucleic acids: Studies of the DNA/RNA
