5. Name one common method used in virology service delivery to detect the presence of viral genetic material.
Polymerase Chain Reaction (PCR) is a common method used to detect viral genetic material in virology service delivery.
6. How do serological tests differ from molecular tests in virology service delivery?
Serological tests detect antibodies produced by the immune system in response to a viral infection, while molecular tests directly detect the virus's genetic material.
7. In virology service delivery, what does the term “viral load” refer to?
Viral load measures the quantity of virus present in a patient's blood or other bodily luids. It is often used to monitor the progression of viral infections and the effectiveness of antiviral treatments.
8. What safety measures should be in place for the packaging and transport of infectious viral specimens in virology service delivery?
Specimens should be properly packaged, labelled, and transported in accordance with international guidelines to prevent contamination and ensure the safety of laboratory personnel and the public.
