You are a nurse and you suspect that you may have been exposed to a particular virus. You and your health care provider decide to perform a hemagglutinin assay. A sample of your serum is taken and added to a sample of virus. Next, the virus and serum sample are added to erythrocytes. Upon examination, you do not see any agglutination occurring. Which can you conclude from these results?
The test result suggests you may have been exposed to the virus, and your serum contains antibodies against the virus.*
EXPLANATION: you can have the virus and the cells don't have to clump, if serum is involved, this and the antibodies themselves can prevent clumping despite having the virus
