Frequently Asked Questions:

1. Q:

Who is eligible for the COVID-19 test?

A: Everyone is eligible for the COVID-19 test, especially for suspected case, e.g. those arriving in Hong Kong in the past 14 days, having direct or indirect contact with confirmed case, with symptoms of acute upper respiratory illness, fever or pneumonia.
   
2. Q:

What can be tested in this test?

A: Virus nucleic acid in deep-throat saliva specimen.
   
3. Q:

Are there any other test methods apart from the deep-throat saliva test?

A: The most accurate methods are nasopharyngeal swab and throat swab, other method includes blood test, which measures the amount of antibodies present in the blood.
   
4. Q:

Is blood test accurate for testing antibodies against COVID-19?

A:

Generally speaking, level of IgM antibodies in patients’ immune system will start to rise after day 7, while IgG antibodies will start to rise between day 10 and day 14. If people with symptoms presented with IgM antibodies, it can be confirmed that he/she is in acute infection. However, in the first 7 days (window period) of an infection, antibodies may not be detected and resulted in false negative.

   
5. Q:

Is it more accurate to use nasopharyngeal swab and throat swab to test virus nucleic acid?

A: Yes. However, the procedure for the nasopharyngeal swab or throat swab test is in a relatively high-risk one, requiring healthcare professionals to wear a full set of personal protective equipment (PPE) which is not suitable to perform in our clinic.
   
6. Q:

What should I do if I would like to do the test?

A:

Please refer to the Information Sheet for Tele Medical Consultation during COVID-19 outbreak and do the online registration in our website.

   
7. Q:

Why the tester should not visit the clinic to go through procedures or submit specimen to laboratory in person?

A: Under the consideration of public health and avoidance in spreading the virus, the tester needs to quarantine at home and not recommended to go to crowded places or clinics before the report is available. Therefore, we have asked tester to send an authorised person to our clinic to perform procedures, collect specimen bottle, send specimen to laboratory and collect test reports at clinics. (Specimen bottle delivery/specimen pick-up service will be available)
   
8. Q:

Will the authorised person get infected with COVID-19 by sending specimen bottle to tester or sending specimen to laboratory?

A: The authorised person will not be infected If instructions are strictly followed: Both the authorised person and the tester should wear a mask, hand over the specimen bottle and related documents in the shortest period of time and perform hand hygiene with 70% alcohol-based handrub before and after contact.
   
9. Q:

What if the tester is unclear with the test procedure?

A:

To ensure the tester clearly understood relevant procedures, our clinic doctors will explain the entire procedure and details before testing. Infographics and video will also be provided for reference.

   
10. Q:

What if patient decided not to perform the test after doctor has explained the entire test procedure?

A: The test is an agreed decision between doctor and tester. Tester may undergo observation for few days first if there is low risk of infection. However, it is recommended to do the test if situation changes or any symptoms arise, or has close contact with confirmed case.
   
11. Q:

When will be the appropriate time to conduct the test if the tester has just returned to Hong Kong or just had contact with confirmed or suspected case, or just started to have mild symptoms?

A:

Generally speaking, the test should be conducted as soon as possible if the tester did not wear a mask before returning to Hong Kong, or has been in contact with confirmed case for a long time, or has serious/obvious symptoms of respiratory tract infection such as fever, cough, shortness of breath.

If the tester has been wearing a mask and the person contacted with has not been diagnosed with pneumonia, or only involved in indirect contact, or tester presented with no symptoms, he/she may consider conducting the test after observation for few days.

Regardless of whether the test is performed or not, it is necessary to wear a mask within 14 days and maintain hand hygiene by using alcohol-based hand ru b to prevent the spread of infection to others.

   
12. Q:

Why is it necessary to collect specimen immediately after getting up?

A: The principle of deep-throat saliva test is to collect secretions from the upper respiratory tract or deeper parts of the throat. Saliva concentration is the highest right after getting up in the morning and before brushing your teeth, so there will be enough amount to ensure the accuracy.
   
13. Q:

Will collecting deep-throat saliva at home spread COVID-19 virus to other family members?

A: It is recommended to carry out the procedure of collecting deep-throat saliva sample in a separate room or toilet. First, clean your hands with liquid soap or alcohol-based hand rub, make sure you wear a surgical mask properly before clearing your sputum. Then, remove the mask and spit the sputum into the specimen bottle. Cap and tightly seal the specimen bottle, wipe dry the surface, and put the bottle into the specimen bag straight. Next, wash your hands and put this specimen bag into another specimen bag.
   
14. Q:

Will it affect the deep-throat saliva test result if there is no sputum and only saliva, or vice versa?

A:

Tester may rest assure that either sputum or saliva is fine, he/she only needs to spit out the deep-throat saliva right after getting up. Remember not to force too hard as it may easily hurt his/her throat or trachea and cause bleeding. Please follow the instructions and spit out saliva or sputum from deep-throat.

   
15. Q:

How much saliva is required for the test?

A: Only 1 ml of deep-throat saliva will be enough. In general, the tester will see a liquid volume of the size of a ten cents coin.
   
16. Q:

Why is it necessary to seal the specimen with two specimen bags?

A:

This can reduce the risk of infecting COVID-19 caused by the inadvertent contact of deep-throat saliva specimen.

   
17. Q:

Why is it necessary to send the specimen to laboratory within four hours?

A: To ensure the accuracy of the test result, specimen should be sent to the laboratory as soon as possible.
   
18. Q:

When will the tester receive test report?

A: The report will be sent to the clinic in about 1-2 working day, and our staff will call or send a SMS to notify the result. Original report can be collected at clinic by the authorised person.
   
19. Q:

What does a positive or negative test result mean?

A: If test positive for COVID-19, it indicates that the tester’s deep-throat saliva contains the virus nucleic acid, should immediately notify the Department of Health and send to the hospital for medical treatment. The specimen will be sent to the government laboratory for further testing. If test negative for COVID-19, it means that there is no virus nucleic acid in deep-throat saliva.
   
20. Q:

Is it necessary to re-test after several days, such as 7 to 14 days if the test result is negative?

A: It depends on the situation. (1) If the tester experienced with symptoms after the first test, he/she needs to notify the clinic and the clinic doctor will consider arranging a second test for the tester. (2) If the tester remains asymptomatic, the chance of receiving the second test is low.
   
21. Q:

Is a negative test result equals to not being infected with COVID-19 and the tester can go to work, return home, and does not need to wear a mask?

A: No, if the test result is negative, it means that there is no COVID-19 virus nucleic acid in deep-throat saliva. However, under the consideration of public health, it is necessary to wear masks in crowded area and maintain good hand hygiene.

If a friend who dine together is infected with COVID-19, there is a risk that you will be infected.
