Viral Tests

Why It Is Done

A viral test is done to:

  • Find a viral infection that is causing symptoms.
  • Check a person after exposure to a virus. For example, a viral test may be done after a health professional is accidentally stuck with a needle to see if he or she became infected with the virus.
  • Find a viral infection in a potential blood donor to prevent the donation of infected blood.
  • Find a viral infection in an organ to be transplanted.
  • Test a pregnant woman who has a high risk of passing a serious viral infection on to her baby.
  • Check if a person has immunity to a specific virus.
