What kind of tests are available?

There are two main methods for detecting COVID-19 infection.

The first type is a very sensitive test that uses a technique called RT-PCR to identify viral RNA. Test sample is taken from the mouth or nose. Even a single virus particle can be detected in this test.

The second type measures the response of antibodies in the serum to the virus. Various antibodies are produced by our bodies after virus infection. Some antibodies are very useful in killing the virus and avoiding virus infection, while others are less useful. Although it can combine with the virus, it cannot help to fight against the virus.

How good is the current COVID-19 test?

The RT-PCR test is very sensitive. Once the patient recovers, the RT-PCR test can no longer detect whether the patient has infected or not as the body will clear the virus. The RT-PCR test can be completed in a few hours and you will receive the report within a few working days.

It usually takes several weeks for our bodies to genereate antibodies against new infections. The antibodies can remain longer in the blood than those of the virus, providing a record of past infections. However, no existing coronavirus antibodies tests have been examined comprehensively to ensure its reliability. This is the reason why WHO guideline and Hong Kong public healthcare sector recommend people to use RT-PCR test. 。

The principles of blood test and RT-PCR test are different and cannot be directly compared, but the two tests can be complementary to each other.

Pros and cons

Get results in as fast as 15 minutes

Limitation

The samples need to be tested in a laboratory. The report will take 1 to 2 days to obtain.

It takes 7 to 10 days for the body to produce antibodies to the coronavirus. During this window period, the virus may not be detected and a false-negative result will be obtained.

Please consult your family doctor if you have any questions about the tests.
