A medical student was hospitalized into the infectious diseases unit on the 2nd day after the disease onset. The patient is suspected to have infectious mononucleosis. What results of laboratory analysis can confirm this diagnosis immediately on the day of the hospitalization?
- A. Cytomegalovirus antibodies were detected
- B. Herpesvirus was isolated
- C. Fourfold increase in number of antibodies to Epstein-Barr virus was detected
- D. IgM antibodies to Epstein-Barr virus were detected
- E. IgM antibodies to herpes simplex virus were detected
Hint
On the second day of illness a rising antibody level cannot yet be shown; think of the immunoglobulin class that appears first and is detectable in a single sample.
