Q: How does the rapid test work?
A:
1. Obtain DNA sample from a patient
2. Introduce primer to synthesise DNA; this will amplify DNA material in sample to detectable quantities
3. Detect the presence of coronavirus DNA using the virus-specific probe

Q: Why does the rapid test take so long?
A: DNA sequence of coronavirus wasn't known initially, hence requiring multiple tests, and increasing wait time. Now with its sequencing known, @HKUMed was able to develop a test that led to speedier results.

Q: What is a “false negative”?
A: The incubation period of #SARS-CoV-2 can be long, and viral shedding may only occur after 3 to 4 days of infection. Rapid tests carried out during a time when viral concentrations are low may not detect the virus. #KnowTheFacts #COVID19

Q: Are CT scans a possible alternative?
A: Yes, but with limitations. Many factors are considered during diagnosis including medical history, testing results, and clinical observations. CT scans alone may not be accurate.
