Solution
The statement "PCR is commonly used to determine if a patient is infectious" is true about diagnostic testing for viruses.
PCR, or Polymerase Chain Reaction, is a technique used to amplify small segments of DNA. In the context of viral testing, it's used to detect the presence of viral RNA, which would indicate that a patient is currently infected and potentially infectious.
Serology tests, on the other hand, detect antibodies in the blood when the body is responding to a specific infection, like a virus. This can be used to determine both exposure
